I want to get a flowmaster 80 series, but the one i can get for a good price from a guy has is 3" inlet and 2.5" out. Will this fit with my stock pipes? i dont want to get all new pipes. And is it worth getting a high flow cat? thanks I know this might have been answered before but i did a search and couldnt find an answer.

Thats the one I got from summit racing for $87 shipped. 3" in and 2.5" out. My stock piping is 2.25". If you take it to a muffler shop, they will be able to put a coupler in there to make the two compatable... i just had it done last week... sounds awesome. Mine is all stock, but hearsay is that if u ger a high flow cat, u will need an o2 sim... 50/50 chance. because your computer does something funky... maybe someone else could explain this better94 bird 3.4L Racing Green<br />80 series flowmaster<br />3 1/2\" Chrome tips<br />Deck, amp, sub, and upgraded speakers<br />Delphi XM<br />5 spoke 99 Trans Am Rims<br />Clear Corners<br />Sylvania Silverstar Lights -
