I couldn't see any system that actually made a difference with the valves other than this one.



As far as fitment, the shop had to create a transition piece since the Flowmaster and Borla pieces were essentially the same size. It was no problem at all and it's all buttoned up.


I really like the black painted system. It tucks underneath and doesn't appear hanging out like a big bling set of wannabe balls. YMMV. I don't like how the the outlets on the exhaust are different, but I may get used to it. The Delta 40s (the quieter ones on the inside) are narrower in inner circumference, but then have an effect to them by having more material inside vs the outlaws. They are the same outer circumference. I'll be happy when they are covered in carbon. Poor me right?


They sound fricking amazing. I finally have an NPP that is useful for my purposes. The stock was rental car quiet with valves closed. And the passenger side rattled like a cheap tin can (epoxied under warranty, then I just gave up). Now I have a mildly, ever so mildly, aggressive exhaust with the valves closed and an absolute blast when the valves are open. In both modes, the sound is deeper, with valves closed just ever so sweet and with valves open, just like an American V8 should sound. I drive a manual and it does get a little boomy around 1,800 with the valves open, but with a manual it works just great for what I want.



I now find myself using the NPP more. I used to be in track mode all of the time. Now I'm able to use tour and sport mode more than ever, and stealth before I turn it off.


Sweet! I’m considering buying flowmaster a scavenger x pipe for mine, to go with the axle-back I already have. Not sure if it would be enough of a difference to be worth it though
