Ive done it a few times and imo it is a bit of a pig,if your lying on the drive with the front on ramps and very little clearance.
Doing it on a proper lift would be pretty easy though.

Hi Andy B,
             did we not meet before on the Yahoo Senator site? Senators were better in that the down pipes to cats and cats to middle sections were always joined by nuts and bolts, so if they broke off it did not matter.

I have found drilling out the broken bits of bolt tricky. They seem fairly hard, nearly as hard as my drill bits, and if the drill bit breaks off in the bolt I have a real problem. Is there any particular technique of drilling through the bolt?

 

[albitz]

Good quality sharp drill bits and a slow drill speed so they dont get too hot and lose their strength ime. Kills the arms though if you dont have much space to work in.

Hi guys,

As we're on the subject of exhaust removals is it worth trying penetrating oil/fat wrench (or flare wrench even) first if they're rusty or just getting straight on with the heat?

[Gaffers]

Want to bring it over here?  If I can get it on the lift it'll be easy, if not there's a pit and if all else fails I have done it on ramps

Thanks for the advice and comments and thanks Swordfish and Guffer for your offer of help  , unfortunately the cars been parked up for a few weeks and Ive unknowingly let the the MOT expire so its currently sitting on a 'Failed Emissions Cert' since last week and kind of narrows my options a bit and hence why it needs to be local

I'm mobile if you need buddy

Cutting a slot in the flange helps with bolt removal and all you need then is a nut and bolt to replace

Hi Andy B,
             did we not meet before on the Yahoo Senator site?  ......

Hi Terry.
Yes, I'm one & the same Andy B of the Yahoo site 


As Albitz says, use a decent drill & a steady hand with a reasonably powerful drill & take your time. You're right, you don't want to have the task of removing the broken drill from the down pipe.

Hi Andy B,
              great to meet you again in cyberspace! I still miss my Senators, did my most memorable journeys in them, cruising all over Europe at speeds (up to 150mph) that were beyond dreams in my childhood. In the Haynes museum there are Jaguars, Rolls Royces, Bentleys, Duesenbergs, etc, that in my childhood I drooled over. My father bought his first car, a pre-war Morris 8, in 1951, and I thought it was great. It failed to climb the hill from Wookey Hole to Cheddar it was so under powered and lacked a fourth gear. I never dreamed then that one day I should own a vehicle that could cruise all day in the 140s. My last great run was from Hamburg to Le Havre in six hours. Happy Days! And all done in a Vauxhall Senator 24v.

Hi Elite Pete,
                by a slot in the flange do you mean a saw cut radial to the screw hole?

I changed my system on my own just using two axle stands - took just over an hour because I had to drill one of the bolts out. I wish I'd sprayed the bolts a couple of days before with some penetrating spray or something.

You only really need to get the front up for the bolts into the cats I found.

My local tyre place fitted my current exhaust for about £40. Worst case, cut and drill cat to mid pipe bolts. Then if it needs to come off again, it is always nice and easy nuts and bolts

[viper357]

Worth going to one of those places where you can rent a lift/area in garage?

They do that? Where do I find these places?
