making a custom Catback need help
Ive been debating with myself for a while now...i sold my Injen Ses because i didnt really get any power out of it so i became disapointed now i just ordered a magnaflow muffler for a good price and im going to do the piping next week...My question is im going to go from 2nd cat to muffler but should i go 2.25 piping or 2.5..most of the cat backs that are out are 2.5 but im afraid of losing to much backpresure...what do u all think

don't worry about backpressure - here is a little test of axle backs we did a couple of weeks ago
note the dyno graph of us running no exhaust at all - still picked up everywhere in the power band

here is the graph for the lazy
002 - green - stock axle back
003 - blue - no axle back
