HP gains over stock exhaust
I will be changing out to a HFC on my 07 coupe... is it worth spending money on a new exhaust? Im happy with the sound of my stock and have heard that the Cat is were all the resistance is.... So question is HFC + stock exhaust or HFC + aftermarket exhaust and is there any info supporting HP gains with aftermarket exhausts?

No cat, but not quite a straight racing pipe either. Has shown some pretty ridiculous gains, not to mention a bit quieter than HFC's by all accounts. I'd pick them up for myself if they weren't so dang expensive.
