I spoke to someone ( can't remember name) at Nameless about their 3" overpipe/midpipe coming soon and related power loss and they didn't expect to see powerloss with this setup. I also know from trolling s2k forums as I had planned to buy one before the snap decision to buy the FRS, that 3" actually lost power in some cases.

Supposedly we loose low end torque but gain hp in the upper rpms with a larger exhaust. Might benefit some but hurt others. Maybe someone can chime in or test this out.

Most of the s2k dyno plots I've seen after a 3" showed higher flow rates but lost tq on the low end.
I just don't want to drop $1k and it be worse off.
