is that an okay cat bypass pipe to buy for my fiat 55sx? (how doe sit fit on? totally replace the cat?) etc etc.. thanks

front bolts on, back slide fit, same as the cat

Dave.. your a legend..



Do i need to use any sealer? (also.. i tohught the cat goes up into the engine? part of the pipe?) or am i talking jibbirish? and installing this wont make the engine noise really stupidly loud will it? i knwo it amkes it louder.. but i dotn want a loud cheap nova sound if u know what i mean..

Cheers. Steve.

you thinking of a mk2, they have cat more up in the engine its part of down pipe on them, yours is the first box that you see under the car, just after the down pipe, you will need 1 gasket fit it dry
