Non-NPP exhaust sound compared to NPP

Bumbleboy92 · 02-08-2019, 11:19 PM

So with the few exhaust related threads I've seen on the main forum, I wanted to see if anyone had an in-person experience with my inquiry.

I have a v6 with the standard exhaust (non-NPP), I'm aiming for the quad exhaust look and don't really care to control the NPP valves. I'm trying to see how much of a difference the two exhaust would sound like. Essentially a v6 non-NPP vs a v6 NPP with fuse 51 pulled. I'm not looking to wake the neighbors but want some sort of sound increase if I'm to change the exhaust.

Right now these videos are the best I could find comparison-wise

Love my NPP - 2018RS 1LT- One thing the video is missing on the NPP is mine will "pop" or backfire when I push it to red line and up shift. It will do this in 1st and 2nd (never red lined it into 3rd to see if it does it there as well as I was at/ near 100mph already and not on a track!). I first thought this was something wrong, but quickly Googled and found it was a cool feature.

As my son says, my 18 Camaro sounds the way I wish my 01 Vette sounded. Chevy did this RIGHT!
