Believe me when I say I've searched. I have searched simply for "de-cat", and have read every single thread that looks relevant. I also tagged a reply on a different exhaust thread but haven't had any replies, presumably down to the irrelevant title. Or because everyone hates me.
I want to replace my exhaust. I want something stainless (ie light and not rusty) to replace my current non-Pug but standard ten-tonne rustpile. I don't want anything loud, which basically lands me with Jetex according to all the threads I've read.
However, while I'm there I might as well sort the cat as well, again I've got the standard heavy rusty steel one.
I know the deal with the de-cats generally, potentially lost torque but maybe better power up top. Better noise, probably some popping and banging just for fun as well.
However, there are no threads which seem to compare the de-cats. Possibly because no-one's ever owned more than one kind, I don't know. I'd keep the old cat in case it's ever needed (ahem) so no need to go into the emissions issues. Whilst it's basically just a bit of pipe, it does seem there is a bit more science to it than that.
What's best to go for? Or are they all the same? Magnex seem common but I'd guess they're louder as per their exhausts. Devil seem to be pretty well thoughts of; PugSport also do, but they're like hen's teeth.
I do *not* want anything loud, I'm all about saving weight and making a nice noise. I also understand that heat-wrapping the de-cat can help keep the noise sensible.
Does anyone have any experiences? It's a dedi track car so pops and bangs aren't a massive issue, but I don't want to look like a chav on the roads. I do *not* want to fail any noise tests on track days either
If anyone has any input, it would be much appreciated
