Oh okay. Maybe you should get Amuse axle-back with Motordyne mid-section, stock HFC, it not too loud compare to Meisterschaft. I hear it in person on G37 coupe, sound pretty good and a bit louder than Nismo 370Z with factory cat-back with aftermarket HFC.

I couldn't tell how loud my cat-back because I am hard of hearing, I wear a hearing aids in left ear and am deaf in right ear. That why loudness is hard to tell, my hearing buddies tell me my exhaust set up is loud but it do worries me when police creep up behind me or sideway on the quiet empty road at night, but so far, it not a problem for them yet.

What brand of HFC would you get? I like Berks HFC, very strong design.
I would get AAM HFC because nobody is running them yet in my area, I like to take different route to compare with Berks HFC on my buddie's G37 coupe, and we chat for like a hour about HFC lol.

Oddly, for 7AT 280whp is a lot but there were a customer's G37 coupe with 7AT did a UpRev tune PTUNING, his mod is full Tanabe cat-back system, not sure what intake he had, Berk HFC, he push more than 300whp on the dyno.
One thing I know is manual transmission can push more than 7AT.

Yeah, every car is vary in whp on dyno, it depend how aftermarket part perform on each level. I do understand the noise of exhaust is concern for some drivers. I just like it loud.
