What one do you all reccomend?

Just put some grotts on my car, with a offroad pipe, and not a fan of how it sounds with the corsa i have.

Corsa isn't going to go anywhere, so cats are the next option.

What do you reccomend?

QTP's y-pipe would probably work cuz their headers are based off of the grot design. Call them up and ask to make sure though.

If you get the QTP Y prepare to have a local muffler shop do some work on it to stop all the leaks. From what I read it's damn near impossible to get one bolt it on and have no leaks. I can deffinitly back that up from my experience with mine.

the grotts i have have ball style flanges on them, so it appears the qtp one won't bolt on.

Think i'll just weld some cats into the Y i how now,..... $500 for a y pipe is a bit much imho, seeing as i paid less than that for the headers and catless Y (used)

yeah get some magnaflow cats off of ebay for $50 each. From what I hear they flow just as well as the ones that cost a lot more.

Or else get the TSP Y-pipe which is only like $350 I think. They use good cats too...i forget the brand either carsound or RT. here ya go:

Dynomax powercats are very compact and free flowing with a metalic substraite core.
