If you leave the cat in, you'll be fine, otherwise you'll have an 02 sensor code, which can be tuned out. Speed daddy headers will do you just fine. they are under 200 bucks.

So are they just a bolt in replacement to the factory manifolds? they connect to the downpipe fine?
they replace the manifolds and downpipe, and bolt directly up to the catback exhaust.
Your factory cat will not work with headers, you will have to either cut it out and weld it back into the downpipe or buy a aftermarket cat and install it in the downpipe section for the cat.
Yeah, for now im thinking just leave it in there. If i put headers in but otherwise leave factory exhaust until i can buy the glasspack and mullfers itll flow alright still?
factory catback flows perfect.
A glass pack and mufflers are never needed. Most will sound like poo anyway. Mufflers wont increase flow or horsepower.
I know it wont increase horsepower but i want the very low note of the borla pro mufflers.
