<font size="2" face="Verdana, Arial">I'm running a 30" resonator, with an unknown series flowmaster. I got the muffler for free from a coworker who had it on his civic. It was extremely loud on his car so I'd guess its a series 50. All the piping from flex back is 2.25. I still have the stock flexpipe or as I call it the "torque step flex section".Originally posted by bugshack:
Hey Cameroon I see your in Pico Rivera, I went to Pioneer High, too long ago to mention. I see your using a custom Flowmaster system. That may be why your still getting some good lowend power. What series are you using? and what size pipe?
