In the next couple months I want to 'update' my exhaust system. I've decided on the Magnaflow muffler, I just have to find it in a store here or go online.
I've also read people'* sigs who have "Hi-flow CATS" and others. What do people suggest in terms of CAT converters? Where would I find them, etc. I have little clue about these types of mods yet so bear with me please. I would love to have the manifolds ported, and everything else (headers...) but I honestly don't see all that as being affordable right now. I'm looking for performance, but not a huge hole in my pocket.
Also, is it possible to get straight piping to replace the curving stock piping? Would this help with hp/performance or should I keep the routing stock and just replace the muffler/CAT?
Besides the muffler and exhaust tips, I need help on what I should do. I appreciate any help you guys can offer. Thanks
