i have a 2.5'' tru benz catbak and it seems to have alot of exhaust drone around 2k rpm... this drives my gf crazy and i was wondering if anyone had any idea to make this a little more manageable?

Yep, I know exactly what you mean! I guess you could add a resonator to the front pipe

Just go faster so you are not sitting at 2K. I find my FSWerks Race Exhaust sounds pretty good at 7K.

Has nothing to do with it. My stock piping droned with a muffler on it. Op, et a resonator on the front pipe and it will be better.

I dont think its just 3K i think its when the engine matches the power it needs. If im going down a hill and im on the throttle so the engine matches how fast its going it seems quiet but going up a hill and its pulling hard its super loud.

Mine did the same until I put a resonator on it. Now its not so raspy.
