i put a walker 3yr g tee rear box and some 2yr centres. noise level is spot on and sounds good when you want it too.

did do a vid of the noise. will have to dig about.

i have seen back boxes with a small drain hole in them also as standard, good idea just to drill a small hole in it

The trouble is, I don't know what system I should use to give me the same level of refinement I had with the OE one.

I would say an Eternal system might be worth a punt. It's a little noisier than OEM but not in an irritating raspy way .. on a V6 , at any rate. Not too great an outlay to try one either. :-/

The problem with drilling drain holes is that drain holes drilled during manufacture would have been done before the exhaust was galvanised. I suspect drilling one afterwards will provide a nice starting point for the tin worm to get a hold.

I have eternal on the MV6. Yes, noisier than the original OE's, but not noisy like the usual junk the likes of ShitFit and ATS through on.  I believe the external ones are just KT ones?

Certainly doesn't have that annoying, tiring drone that many patterns have when cruising...

Thanks to both TB and Kevin

I'll look at Eternal's site.

My OE system finally became intolerable in January at 100,000 miles & 7 years. Mind you, I had patched it up with a pilchard tin for the MOT in 2010.

Got a secondhand OE system off ebay for £50. Went straight on and looks like it will be good for 18 months at least. That seems like good value to me.

Exhaust systems are made from pre- aluminised(not galvanised) steel, and any welding, fabrication or drilling takes place after the raw material has been aluminised.
Whenever I fit a new exhaust to my own vehicle I paint all the welds, including the machine weld that runs the length of the tube with a zinc rich paint such as Galvafroid.
I also coat the joints and clamps after fitting.
IMHO it would be a good idea to coat the welds on the inside of the tubes at the rear of the middle section as well prior to fitting if you want to really maximise the life of the system.
