The entire NPP muffler itself is an aero piece, aftermarket exhausts typically create a giant cavity there that causes the rear diffuser to act as a small parachute at higher speeds, the solution to which is this belly pan.
As you suspected, the crushed sections have proven zero effect on power output all the way up to 1000 hp, possibly even higher, they just look butt ugly  |
yeah i have mine set to track all the time. it is loud enough for me lol.
i did not think of when taking the npp off that you would mess up the aero. yeah the air would catch the diffuser, interesting. yeah saw a racerx video the other night where he replaced his LT1 exhaust and he could not believe the crushed parts would not affect it. most of those aftermarket exhausts are quite expensive also. and it is nice to keep the valve options that come with the npp. thanks will look at that belly pan too.
