thinkng of getting a twin 3" into a set of extractors havent done much research so i better ask before i run out and do it. the question is im going for sound over power although i want to gain aswel will the 3" be too much im not planning on further mods like cam etc. Im guessing u wouldnt have as much back pressure therefore getting less power say to a 2.5 am i right" im not fussed if i loose a couple of KW in gain over a better exhaust note any help appreciated.
