x2 with Sebba, here in good ole South Carolina we dont have emissions laws so a lot of people just run straight 3' pipe straight back, sounds good, LOUD turbo spool, and better flow. so you can check your stat emissions laws. and if you have to use a cat, don't fret on the HP loss... in an article of Import Tuner a month or so ago there was an article with the difference between a cat, high flow cat and test pipe. . . the difference was 1hp gain each step up, so you won't be losing that much.

yea they had the dyno runs to prove the differnces... from stock cat - high flow cat = 1hp gain and from high flow cat - test pipe = 1hp gain. i want to say it was in the november edition of Import Tuner, i think it had an orange sylvia on the front w/ carbon fiber hood. i sent the magazine and 5 others to a friend of mine in Iraq so i don't have it anymore. i think it was on a turbo'd integra pushing like 8-10 lbs.... i can't be sure though. but yea on the same car running the same boost, it was 2 hp gain.

thats kinda small boost though. IDK i guess it will really depend because to use a stock cat that mean you MUST use a smaller downpipe, so already there is more restriction. And i think the changes in HP is gonna be very boost dependant

I never really thought those high flow cats were all that great anyway. They are pointless.
