hiya, how conceivable is it for a reasonably competent DIY mechanic (a.k.a me) to change my stock manifoilds for some ACT stainless items? i have heard horror stories of inaccessible bolts and skin loss etc, but i would have a crack if anyone else has done similar and recommends it...

all the best - shorty

presumably would be fitting a pre-catless pair.

No help I know but I'm in the same situation. One gasket blowing and a desire to take this opportunity to fit some new ones without the precats. I hear it's a long hard knuckle grinding job.

Paul (The Surveyor) did his...i am sure his skin has grown back now!!!

I am going to get some de-pre cat manifolds soon and hopefully persuade paul to undo the awkward bolts while i supply/sip cans of beer!!!

Aparently it is awkward!!!

I haven't changed my manifolds, but I've had them off a few times to replace gaskets and also tightened them up a couple. The bolts are :cendored:s to get to, but time and patience all is fine.

I changed mine on the Griff and it's not too bad as long as you have a good selection of spanners and sockets. Helps to have the car jacked up so you can take the front wheel off the side you are doing, as some bolts are much easier to access from underneath. Only trouble I had was trying to get the manifolds and Y-pipe to line up in order to get a good enough seal. Still not perfect now but good enough for MOT. Anyone in the Sussex area that wants a hand , etc, let me know.

I've had the offside manifold off. If you have hands like shovels or a bunch of bananas it will be pretty awkward: there's not much room. My car didn't have many miles on it and the bolts were still in quite good condition, so they weren't too difficult to remove. But, as someone else suggested, get the front end up on axle stands.

My suggestion is that you have a go at the easiest looking bolt first, on the basis that they are hopefully all in the same sort of condition, so you'll then know what the rest will be like to remove. Then move straight to the most difficult looking one: if you can remove that, you should be able to complete the job. Good luck!

i'm not likeing the way this thread is heading...... Just pick on the guy with the small hands!

But as said before the passenger side is easier than the drives side as the starter motor and upper water pipes seam to get in the way on that one. It is just conventional spannering though, not a great deal of skill needed (otherwise i would have taken it to HHC) but just a job not to be rushed. And yes, the lower bolts are much easier to get at from underneath. More than happy to lend a (small) hand though, just give me a shout....

Cheers guys, i am rapidly going off the idea... any ideas how many hours labour is involved if i take it to a dealer? one would hope its exponentially less than DIY labour time, being as my patience levels are fairly low.

Cheers - Shorty

Just had mine done at Offords

I think the labour was about £200 but I had a number of jobs done so may be wrong

Worth giving them a call (Bill) - I was very pleased with the work they carried out

I would have thought this would pre-stress the exhaust leading to cracking in the not too distant :hehe

In theory both the engine and exhaust are rubber mounted, so no, I don't think so. It will help promote oil leaks if you jack up under the sump though.
