My plan is to pick up the AAM s line midpipe to go along with the short tails. Now they claim that is pretty much an increase in 20whp and torque, but from reading this thread it seems like I would lose power? Isn't the AAM s line and short tails combo pretty much a straight pipe catback I guess? Thanks fellas

with my regular set-up my only backpressure was my mufflers and it was a monster.....still is
i was tuned at AAM with my original set-up (in sig still) at 324whp and 258wtq.
i feel that now without the mufflers is the only reason i feel the slight loss in tq. and again it's butt dyno and it may be my ears playing tricks on me.
i say this since now with it being so loud so quick my brain may be telling me i should be going faster than i am based on pure sound......if that makes sense?
i have ran the 1/4 in back to back weekends with and without mufflers recently and saw no real differnce in my ET's and other numbers soooo idk.
