i've been searching throughtout the threads and narrowed my decision down to two exhaust systems the hks hyper and the greddy evo2 i want the sound of a v8 beast but i still wanna keep it kinda on the luxury side anybody have/had these two exhaust or any type of input on them

 

the greddy is loud, i think it's one of the loudest for the GS out there. i sat in one and it was nothing but headache compared to my apexi.

i don't know about the hks though
