do you already have an exhaust on your car?

yeah skunk2 catback

you might feel a little difference with a cat and header

are all high flow cats basically the same?

like i know obx isnt that great but do u think their cat would b okay? im lookin on ebay for one and i cant really find much..... u kno any good sites ?

magnaflow makes decent cats

random technolgy makes a decent one
but if you were gonna go for a good header, just stick with the one designed for your car like others on here have recommended

or just buy the header and take it to the muffler shop and let them figure it out. It should only cost around 80 bucks.

my brother had that same header on his 96 gsr with a matching carsound cat and cat back. he dynoed about ~160whp with those mods and a cheapo sri. it sounded nice and pulled hard in the upper rpm range. a word to the wise though, the header hangs kinda low so be careful if you're lowered. my brother bought his header used with a nice size dent on the bottom of one runner.

thanks guys

anyone kno where i can buy a high flow cat besides ebay?
