So, I SHOULD put secondary cats in? Can I just do two 2" secondaries and that's all, then have it just Y into 2.5" ?? Yeah, I don't want any sort of rasp or anything like that. Wouldn't it be better to go like 1.75" from the manifolds though?? Seems like 2" is a bit large to me... What is the I.D. of the stock exhaust anyways, do you know??

Sorry for the nob questions, but just still exploring the site and trying to find what all is on here!
