markssupra Posted March 14, 2008 Share Posted March 14, 2008 Called a local custom exhaust fitting garage and they wanted £50 to fit. WTF I'll do myself. If I fit decat myself any little tips that would help. Like having really bendy arms or a long socket extension to reach the top nuts on the cat.

JODY T Posted March 14, 2008 Share Posted March 14, 2008 are you fitting the 1st cat? To be honest for the grief it could give you ide pay it mate.. If the nuts pick up like they usually do and ruin the thread youll be stuck without a car and a much larger bill to get a garage to sort it.. If the studs start spinning youll be in a hole world of poo as you wont be able to see anything unless the cars above your head.. Just my 2p Link to comment Share on other sites More sharing options...

Just my 2p I agree 50 quid is good compared to a few hours lying under the motor gearbox against your nose and fiddling about trying to get the right socket/ext combi without ruining the nut.

MRX Posted March 14, 2008 Share Posted March 14, 2008 Again I have to agree to paying someone changing the 1st cat, mine had seized and they had to use some thing to melt the bolts out... The second is a piece of cake and easy to do yourself. Link to comment Share on other sites More sharing options...
markssupra Posted March 14, 2008 Author Share Posted March 14, 2008 Thanks for the advice everyone, but I will give it a go anyway. If it looks like it will be a problem I'll get someone else to do it Link to comment Share on other sites More sharing options...
RobSheffield Posted March 14, 2008 Share Posted March 14, 2008 £50 is good! However, if they are anything like most places they will sheer/strip a bolt and bodge it up. Iv done several now for local lads, always use a little plusgas (NOT WD40) and a breaker bar to apply pressure gently - NOT shocking it off or using an air ratchet like they will!

markssupra Posted March 14, 2008 Author Share Posted March 14, 2008 Thats why I would rather try myself as I dont want to pay for fitting and they end up bodging it, although skylineloopy has kindly offered to fit it. What a fine bunch we are on here Link to comment Share on other sites More sharing options...
Mike M Posted March 14, 2008 Share Posted March 14, 2008 Hopefully you'll be lucky and they will break free like mine did with a loud crack and run off smoothly. One of the bolts is a right bitch to get at but not impossible. Link to comment Share on other sites More sharing options...

miko_supra Posted March 15, 2008 Share Posted March 15, 2008 i had to get a blow lamp on the nuts for the first cat nearest the engine. Get them red hot and you need about 1 1/2 foot extension to get up to the nuts from underneath and a decent breaker bar (but the breaker bar cant be too long as there isnt allot of room under the car to play with) Link to comment Share on other sites More sharing options...

mr keef Posted March 15, 2008 Share Posted March 15, 2008 its a nightmare when you are on your back and something snaps mate pay the 50 quid because it can end up in tears and a whole day rolling around swearing;) Link to comment Share on other sites More sharing options...
markssupra Posted March 21, 2008 Author Share Posted March 21, 2008 All done today. Lucky enough the nuts came off fairly easy. Only problem I did have was that the decat is shorter than the cat so it wouldn't join back up properly with the exhaust. So I made a thicker spacer at work and now its sorted. Just need to get boost controller setup now. Link to comment Share on other sites More sharing options...
