General De-cat pipe

[JonnyBoy]

I fitted a de-cat pipe to my Punto the other week; best £35 I ever spent!(Cheers spiky_monster ) The pipes are normally £49 on www.fastfiat.com.
It's reckoned to give an extra 5bhp; I'd say that realistically it's more like 2 or 3 but still makes a very noticeable difference to the car's performance. It's a bit noisy as the cat usually acts as the exhaust's primary expansion box before the gases enter the "proper" expansion box, but its not "Gary-boy Nova" loud. It's a mod that's well worth doing if you want a bit more poke from a small motor; just got to remember to bosh the cat back on for MoT!

I was gonna get this done when I had my exhaust fitted, but didnt bother in the end. How easy it is to fit the cat back on??

It was a bit of a whore to fit, as the bolts holding the cat onto the downpipe were rusty as hell and I had to break out the angle grinder to shift them! Other than that its not too bad. Just make sure you've got plenty of ground clearance (I used ramps) and before you take it off, buy a pair of M8 bolts (around 40mm long, with nuts and washers), a new exhaust clamp for the cat-pipe-to-back-section joint (mine was 48mm) and some exhaust sealing paste.

Thanks for the advice. I dont wanna go near the exhaust so it would be the place I got the exhaust from that would do it. Like you said, MOT time would be a problem.........

i must of imagined this but i thought the cat on mk2 punto was in the exhaust manifold part and you couldt get at it??
