i have the stillen header and the nismo exhaust and let me tell u- the header makes our car feel totally different. TOTALLY different.
Def buy both. my bd gt performance test told me i picked up almost 22hp and 25lb/ft tq just after hooking up the header, w/ no bd tune. then tested it w/ dynolicious for the itouch and it said 21/22 to the same respect. after full tune and such, bd tuner said 232hp 238 lb/ft that sounds redonkulously high, but idc. lol. for a N/A 4 cyl, i'll take it. and idc if its wrong, cus my butt dyno is physically saying its right. and thats all i need lol
however- yes- nismo = best sounding. mandrel bent ftw, not squished. kthxbye
