Anyone with HFC or Test Pipe regrets?

It does make some rasp but it sounds great imo... I think once i couple it with the stillen exhaust the rasp will go away, just as it did in my old 03 g35 coupe with the greddy evo2 i had on it... not a touch of rasp with the greddy but with stock exhaust there was a ton...

but yes one thing I resent, not regret, is cleaning my rear bumper way more than I should have to, esp with a scratch remover because the brownish tint doesnt come off with just a wash. This is with TEST PIPES, i dont think hfc will do that, or atleast not nearly as much
