    Help with fitting an exhaust

    Ok I have just (literally) had my new cobra exhaust delivered to my work. From exhausts.co.uk I am going to attempt to fit this tomorrow as I can't afford to pay for a garage to do it.

    It is just a backbox and I have a remus pipe fitted. Can anyone give me advice as to what tools I will need, steps to take etc PS it is for a coupe

    Can anyone help, I have never changed an exhaust so I am worried about messing it up. Although with a bit of guidance I am sure it will be easy. Any help welcome

    Give it a bit longer for people to reply mate.

    Sorry I can't really help because I don't really know much about cars yet!

    I expect people will reply this evening when theyre home from work etc.

    All the best, james

    is it a cat back system?. It should be pretty easy if you have bought a system designed for a Mk4 because it will fit back where your old one came from and with the same connections.
    I would recommend some kind of socket set, a pair of grips and you will need some exhaust jointing compound (available from car shops/halfords) and some WD40 for any rusted/stuff bolts/joints.
    You will find it almost impossible if you cant get under the car though!. I would recommend either a set of ramps or axle stands.... I have never used axle stands but do a quick search and you will find the best place to fit them under the car. MAKE SURE THE CAR IS STABLE BEFORE GOING UNDER!!!. If in doubt take it to a garage. Also you will probably need another pair of hands.

    You may also need some different rubber hooks as the std ones might not hang low enough for your new tailpipe...

    Hope this helps.

    Sorry just read that its only the backbox to be fitted so it shouldnt be any hassle.

    Also make sure the joints are sealed. Otherwise it will prob fail a MOT.

    Will it have to be welded?

    simple really -

    remove the two bolts (save these -along with the springs) - these might need soaking in WD40 before you start
    unhook the 3 hanger rubbers (save these)

    that's the box off the car.

    fit new gasket to end (inlet side) of back box
    refit new box using the rubbers
    line everything up and refit bolts

    job done,

    and if you posted in the correct forum you might have had a quicker reply - Exhausts are bodywork - they are engine related

    No. If you use the gaskets ffoeg mentioned and some jointing compound then it will be fine.

    Some people would say that you dont need compound but im a plumber by trade so i dont trust any seals apart from rubber without a bit of jointing compound on them

    i have known people to use RTV compound due to exhaust paste flakes off when hot and crumbles .. RTV seals and is helped to dry and seal when warmed up
