Hi all. I'm looking for the least expensive H-pipe or X-pipe that has cats on it. Something like that performance one from Bassani. Also I was wondering how they can actually pass emissions when they have 2 less cats on them than the factory one from my 94 GT. My factory pipe has 4 cats total, that bassani one only has 2. So which one can I get that will be 2.5" and flow better, but still pass emissions? And is less expensive than $500 freakin' dollars.
