hello everyone
i have a NA and im looking to get a single exhaust here.
i currently have an old school hks dual and a PROF 3 " dual, but i want to shed some weight (starting to get in a corner for performance before turbo swap)
does anyone have any ideas as to which is more quiet? the n1 or the hi-power? both look simular, and i just want the more quiet one. thanks alot
russell

 

i like my hks hi power... not to loud... of course i never heard another exhaust on a seven besides mine so sorry.... but i like it

 

i will tell you this having a N1 is allmost like having no mufler at all lol

 

the hks has some kind of resanator(sp???) does the N1 ??
