Message	turbo back to 3" turbo back. More top end power, not to mention the exhaust note is soo much meaner sounding. I have seen what some claim about the exhaust velocity slowing down when going with 3", but if it flows more smoothly (bigger pipe dia), then its flowing. Its all opinion i guess. I definitely felt a power increase after swapping to all 3". The sound alone is enough to make up my mind. It would not cause a hp decrease, thats just insane to say that. The exhaust velocity theory makes sense, but heat also plays a big role in moving exhaust gases down a pipe. The hotter, the faster it goes. 3" all the way , IMO! (Others may disagree,but its from my experience, and Dee Ridgeway's (SlowNinja 675R) My.02 cents :) Shawn300zTT AIM:Shawn300zxTT "I just took 45 min and scrubbed the heck out of my rear" teambushido(San Diego, CA) 19:24:51 12/11/04 1991 Stage _ TT 5spd (Turbo Upgrade in process) 1990 2+2 Na Stage 3 Auto 11 Sec Eagle Talon Tsi AWD, Daily Driver. 2004 Honda CBR 600RR (Candy blue)
