Anyone have NHP headers on stock exhaust
Out of curiosity was googling about NHP headers with the 200 cell cats. Lot of folks running em full exhaust. So was curious if anyone is running them but using stock mid pipes and muffler. Curious on performance effect vs just swapping muffler, sound loudness tone drone. Possible loudness and performance if used with a brombacher exhaust.
So what says our performance experts?
