Title: Gm exhaust numbers
Post by: laney101 on 19 June 2020, 15:19:08
After gm part numbers for 3.2 saloon exhaust. Centre pipes and back box with twin tips

Anyone recently bought one on trade club prices.
How much for centres and backbox

Not had any luck with aftermarket so thinking just buy GM.

The quality of the GM ones dropped to Timex Bosal (ie, lucky to last the warranty) type standards around 10 years ago. General consensus is they are not recommended any more

IIRC, Trade Club went out of the window a few years ago.
I've had a Eternal one on mine for over 5 years now.
Other then a bit of rust around the welds, its still going strong  :y

GM V6 centre pipe part numbers -
LH 93181157
RH - 93181162
Twin exit back box - 93192230. These have steel straight cut dummy tips, and an oval ish silencer - the 'aftermarket' version.
Original clam shell silencer with the slash cut stainless tips - 24425170 (but you won't have a cat in hells chance of one of those!)

I have fitted Bosal to mine - not had a problem with them at all. Good thick steel and a perfect fit. Fitted some angled stainless snug fitting tips to look like the original spec, but would have Bosal systems again without question.

Not perfect but better then the shitty Bosal / Timex shite.  :)
TBH, I do play my quite music loud so probably wouldn't notice it anyway  :D
Just make sure you get the double skinned boxes because they make a hell of a difference even to my ears

Not to mention that you likely won't be able to get one from Vauxhall in the UK. There might be a remote chance of a special order from Germany, but I would imagine it will cost more then the value of your car.

The best bet is one of these kits (https://www.ebay.co.uk/itm/Opel-Vauxhall-Omega-B-3-0-3-2-V6-Saloon-Silencer-Exhaust-System-351/251165535819?fits=Model%3AOmega+B%7CCars+Type%3A3.2+V6&hash=item3a7aa1ee4b:g:94QAAOSwi1pctco0) @ £112 delivered. Make an offer of £70 (+ delivery), they usually make a counter offer which will get the total outlay closer to £100. The  usually arrive from Germany within a week. Or perhaps Poland where they are made. However the listing says these kits are actually now in the UK, for a change.

Some members have also had success with these Gerlach kits (https://www.ebay.co.uk/itm/Silencer-for-Vauxhall-Omega-B-3-0-3-2-V6-saloon-1994-2003-exhaust-system-031/221565829393?_trkparms=aid%3D1110007%26algo%3DHOMESPLICE.DISC%26ao%3D1%26asc%3D20200423072919%26meid%3D70dc69966db44a47970f687a6f292fe9%26pid%3D101110%26rk%3D1%26rkt%3D1%26mehot%3Dnone%26sd%3D251165535819%26itm%3D221565829393%26pmt%3D1%26noa%3D0%26pg%3D2563228%26algv%3Ddefault&_trksid=p2563228.c101110.m1982) @ £127 delivered from Germany. I think they're also made in Poland.

One issue with all of the aftermarket centre boxes is that the pipes are cut, to shorten the packaging length and reduce freight costs. They give you clamping sleeves to join the pieces back together. Functionally they're fine but it makes the exhaust slightly more awkward to fit.

Post by: laney101 on 19 June 2020, 16:51:18
Cheers for replys..

Yes seen ets ... eternal on ebay now all around 100 quid catback.

Some are clamshell type ... some are just oval centre boxs...any benefit to either or is one quieter??

Tios wise not bothered i have original slash cut gm tips of the original exhaust i keep fitting to whatever i buy.

U had clamshell cheap one last time sounded tinny.. this time i fitted a oval box dont know make engine sounds more growly v6 like however its hums like mad on a cruise and does my head in ....

Ive seen bosal backboxs listed no centre pipes though
Title: Re: Gm exhaust numbers
Post by: Doctor Gollum on 19 June 2020, 17:11:45
You could always get a stainless system made to sound exactly as you want it...

Won't cost any more than a genuine one :-X
Title: Re: Gm exhaust numbers
Post by: laney101 on 19 June 2020, 17:33:00
Dont want it to sound of anything.. the original one was silent.. so boominess of cruise thats mainly what im after qhen on motorway dont want to hear it
Title: Re: Gm exhaust numbers
Post by: Doctor Gollum on 19 June 2020, 17:55:53
That's my point. Get a system tuned to be completely devoid of anything. After all, that's why it's called custom ::)

Kids these days...  :D
Title: Re: Gm exhaust numbers
Post by: laney101 on 19 June 2020, 18:09:15
99% of custom exhaust shops could never do what your on about... they are just welders with premade boxs.

Mostly crap..

All im asking for is what people have bought whos got what and how they find it as standard mine qas silent on motorway but when foot down growled lovely. Bow it just crap as got some cheappy exhaust on it.

Ive heard eternal good as people seem to say theyre quiet. Is theyre any others.

Id buy a jetex except its wrong bore too big for n/a and tips are stupidly big look naff

This forum as usual answering unasked questions and going of on tangent.

All i asked for was part numbers of gm system

Thats it. Not a reply to say theyr sh1t... dear... etc just asked for part numbers.. thats it.

All im after is a good standard replacement that isnt boomy or tinny. Not much to ask. Jist as close to original as possible.

No stainless isnt viable as nearly 600 and the jetex system isnt what im after.

Custom made wont be quiet unless spending a lot of money..past jetex money.. powerflow longlife etc all generic boxs pipes etc nothing special spund nice but wont br good on nvh


Cheers to Enceladus   johnnydog   tigers_gonads actually for a nice bit of information and help.

As usual doctor gollum  just not helpful rather people didnt right anything if not goung to help or just be rude about people

You asked a question on a public forum and once again when a variety of people with significantly more Omega experience than you could only dream off give your several different options, you get all narky because 'it wasn't what you asked'.

My last Elite had custom stainless cats, centre pipes and Irmscher back box and was as refined as any standard Omega that ever rolled out of Russelheim.

The OP doesn't want a custom stainless. And probably understandably.

The OP wants GM, but sadly I think will be disappointed by what GM now supply - I know I was.

For the past 10 years or so*, all mine have had either Eternal or ETS exhausts one, with decent results, far better than the Bosal junk fitted by fast fit places.  And if I needed one tomorrow, thats again my first choice.



* Except TBE, which has Eternal mid sections, but Irmscher backbox

Thank you for a normal good response the boy.

Yes I would like gum however if general consensus is the price isn’t justified and quality as dropped then fair enuf..

Eternal and ets again think I’m gonna go with one of them a few people now have said them two and all seem to say have good results.

Cheers again  theboy. Helpful and constructive advice.

Doctor Gollum once again  not helpful useful or needed.  Yes public forum supposed to be full of people sharing knowledge advice etc etc.

And also how the hell do u know what knowledge I do or don’t have .. more knowledge than I could dream of jog on mate keep of my posts as to be your just not helpful in the slightest.

The whole point of 'custom' is that you get, within reason, what you ask (and pay) for... Applies to exhuausts just as much as kitchens or landscaping.

People assume, wrongly, that a custom exhaust means four inch beanz canz on the end of a scaffold pole.

No attitude how about you leave useful comments to people who can give them :)

Me in my Omega

This one 40k
2.6 elite 25k
2.5 mini facelift 15k

How long been around Omega 13years current Omega was dads before mine dad bought 4 years old had it for long time till passed to me.

All work been carried out by ourselves

Cam belt changes suspension repairs body welding electrical issues

I know my way around them quite well thankyou  :) as much as I need to know anyways always be someone knows more. As as people know far more than you.

and what you said about knowledge is irrelevant as to what part number are gym exhaust haha or what exhaust is quiet. Simple questions simple answers as said the boy has helped in one reply. You haven’t helped at all with any of the posts you put in this

Once again I know but unfortunately (from experience) most outfitters ie power flow long life etc just franchises they know very little of exhaust design. How a system scavenges weather a x pipe is needed to balance pulses etc so never end up great.

I true custom shop yes that design it well would be amazing but as you said be very very expensive to get it as I be had quotes for a proper designed system in past looking at 1200 to 1400 for cat back. Just can’t justify it

I do agree with you there. Before I fitted my Jetex system, which I never had any issues with noise wise, my car was booked in to Long Life at Weston-on-the-Green near Bicester. I'd told them that I wanted a complete duplicate of my original GM system on my 3.2 and they agreed that they could do it. I arrived for my appointment, my car went on the ramps and I just managed to stop the guy from cutting the Cat flange off. I asked what the hell he was doing and he said the easiest way was to weld the new pipe over the old pipe. I then noticed that they were going to run a single pipe instead of dual pipe so I got them to remove my car off the ramps and I left without having anything done. Some people have had good results elsewhere but I wouldn't use them or Powerflow personally. Jetex are a matter of choice but too expensive this late in the game for an older car. I have heard good reports of Eternal/ETS but have no personal experience of them. The reviews on here for them are good sound wise, they appear good value and if you've kept your original exhaust tips you could make it look as it was when it left the factory.  :y
Title: Re: Gm exhaust numbers
Post by: laney101 on 19 June 2020, 22:13:07
Cheers for great insight. I don’t mind spending 500 ish on the Jetex just didn’t want to and find out on a motorway it boomy or can hear while sitting at 70 droning away.  I’d have to have tips removed though just not a fan but as you say personal preference.

Yes consensus seems eternal and ets seem good replacements

Yer I’ve had power flow in past they work but that’s it.

Both cats are part of the down pipe and 2.5/3.0 are different to 2.6/3.2 (for the purpose of this exercise)  ;)

Ideally need to be type rated to avoid MoT issues...

Starter for 10...

Obviously that one doesn't mention being type rated, so caveat emptor etc...
Title: Re: Gm exhaust numbers
Post by: Enceladus on 20 June 2020, 04:15:06
Almost certainly it's not type approved. It has the earlier BM Catalysts part code BM91119. Strictly speaking intended for cars registered prior to 1st March 2001 and not legal to sell or fit or use in a car registered on or after that date in the UK.

The BM Catalysts R103 type approved cat is BM91119H. All BM made type approved versions have the H suffix.
The nearside cat is BM91118H or GM 24456830.

In general R103 type approved cats have to be made to a standard of fit, performance and lifespan that's at least as good or better than the factory part. In general that means more platinum, iridium and palladium in the cats. So they should last longer than non type approved versions.

Whether the MOT tester cares to notice is a different question.

I have fitted an eternal system to my 3.2 in 2009 with clamshell center sections and it was just as good as the original FACTORY GM and lasted until 2019 when it went in the usual places on the twin pipes behing the back box.Subsequently fitted 5 more of these to other 3.2's and all good.

Probably 'cos the old one had a hole in it and was blowing...!! ;D ;D ;D :y
Nope, was newly fitted to the car before I bought it and leak free (although it had been fitted wrongly ;D). Still didn't blow after fettling :P

Yeah, its noticeably louder, though not as offensive as most stainless backbones.

I meant the exhaust as a whole (on my black Irmscher Elite) rather than the Irmscher box on its own  ;)

That said, the estates weren't as refined as the saloons, so perhaps that's why. The Barge is double glazed so you can't hear much of anything  ;D

Having had all sorts of Cat back exhausts (Genuine GM from factory, Bosal, no name Kwik Fit type, full stainless single pipe, Full stainless twin pipe) over a number of Omega's I can honestly say the £75 (probably more now) ETS / Eternal twin wall with clamshell silencers is the closest to the original GM (ie refined at all rpm) and best exhaust I have ever put on a V6 Omega, Needless to say all three of mine have the ETS / Eternal exhausts on them currently.
