Couldn't agree more. A quality HFC(F.I.) will provide a cleaner note, if you like loud and ballsy, RTPs are for you. Power wise is pretty moot. I will say, whole cruising or digging into it, the RTPs do have a bit more of a fun factor with that nasty note coming through.

Or **** it, go TT and get the best of everything,

Just a note, some exhausts turn to complete *** on test pipes. MY old HKS and ARK GRiPs responded like hell to berk TPs(maybe the Helmholtz dont like TPs|?). MEanwhile my F.I. CF CBE was just amazing with my RTPs.

After doing a lot of research of dyno charts and comparisons of HFCs vs TPs, the #'s are right around 1-2 hp higher at the peak for the TPs, but slightly higher in the midrange of the TQ levels of the HFCs, so basically nothing unless you're looking for "bragging rights" on a dyno chart.

IF you're planning to remain NA, I'd recommend HFCs>TPs. Keeps your exhaust sexy sounding with no rasp, and will give you the gains you're looking for.
