Sup. I'm putting a b18b in my '99 civic lx 4dr. My old engine has a hole in its block after sucking water into the AEM CAI from when I drove through a puddle (USE THE BYPASS VALVE!!!). Anyways I was wondering what the best exhaust would be. Most likely all the mods i will be doing are intake, headers and exhaust even though i've heard that the b18b is a great turbo. Where to find the cheapest prices would also be appreciated. Thanks.
