ok here is what i got 4-2-1 race header, 2.5 in flex and stock exhaust i am getting rid of the first resonator (the one right after the flex) and maybe the lunchbox (the one at the und where the tip it the big box) you can go to youtube and look up lunch box removal or do it on this forum and it sounds good. a catback only gives 2-3 hp on and n/a car and 4-5 on a f/i in my opinion you pay 300+ for some sound. btw my intake is loud too i have a AEM type by factory tuning it is a CAI
ok sir...you are SOOOOOOOOOOO wrong.
catbacks yield more then 2-3hp. quite a bit more actually. they are a good gain for a NON svt car. a 2.5 is a good set up. a borla or magnaflow is always a good option. however to say its for some sound is just ignorant and foolish.
if you did a race header, 2.5 flexpipe, 2.5 exhaust it would wake the car up big time and would make driving a lot more fun.
oh and to badass3...id be willing to bet you 100 bux that you have an exhaust leak where the flexpipe meets the stock exhaust, unless you had it welded on...the size differenze is too much for it not to.
now do yourself a favor and do it right the first time, from the head back.
