Here's a quick vid of my non-NPP exhaust with short bursts of gas while reversing off the transporter... it's better to hear it live in person but at least this is better than nothing.

Thanks for the vid, still sounds kinda nasty with those spurts of gas! What exactly is the dual mode feature you're talking about. Is it just when you switch to sport or track and it opens up more?
Doesn't the standard exhaust have valves, or does it not activate in those modes and is only used in Eco?
