If I didn't know any better,I was getting on the interstate for a test ride to listen to the sound and it sure felt like it had improved acceleration.It got up there quick.Im impressed with these mufflers.I really wanted the trident tips but these pipes look better in person and I really like them.Im going for a ride today and we'll see how they do.Im running these pipes and the V&H naked v02 intake and it has made a difference.Maybe a FP3 next year.
I believe you are feeling sop correctly Not sure you should be running without more fuel considering you did a/c and pipes. You may want to confirm that to be safe. Also, imo reconsider the FP3, save a little more and get TTS or PV.
The FP3 seemed to be the easiest to use.Thats why I stuck with crusher or V&H products.It seemed to run very well.Ran good with the night sticks also.Decel pop once in awhile.Ive never experienced discoloration of any muffler and the crushers will be my third pair.
