Expierience with the NPP

To all out there with the performance dual mode exhaust, what is the difference between this one and magnaflow or flowmaster. The NPP sounds like crazy and if I get backfire even when I turn the key....i´m happy! Not pretty sure abou performance but it sounds aweeeeeeee.... just release the gas and the beast talks to you its getting better as more you drive it (just has to break in a while)

your talking about two aftermarket muffler manufacturers while the on is stock and has a activator that redirects the exhaust flow to allow for free flow versus muffled. I am not sure they offer that option with their products to be able to have the dual mode ..............

+2 for LTs with highflow cats and M2W switch. Mild = quiet cruise = makes the wife happy. Wild = Amazing and turns heads.

I pulled the fuse on my NPP so that the active exhaust flap stays open all the time. All I can say is that, for my needs, I'm plenty happy with the NPP so much that I'm not considering an aftermarket exhaust. I love the sound. Obviously haven't done a side by side comparison with others so I'm not making any claims re. performance, etc.
