After a sucessful run, we decided we could do better for you. We have taken everything we learned with this design and decided to reset the bar.
Goals:
No price increase
Weigh the same or less than the original full titanium system
Quieter with valves closed
Louder with valves open
Larger tips (4.5")
Fitment for every C6 variant
Follow our IG or development e-mail list for updates on the Ultimate NPP V2
Having tried multple mufflers and listening to customer feedback led us to develop our own valved muffler. Straight pipes sound incredible, but were too crazy for regulary driven cars. Absorption type mufflers muted alot of the exotic sounds, the "drone killing" mufflers resulted in more 4-cylinder sounds, and the OEM NPP just didn't let the headers sing.
Designed to best compliment our 8-4-1 headers
The next best thing to running straight pipes
Larger diameter than OEM ZO6/ZR1
Full size vacuum valves (will retain OEM control or a standalone control will be offered)
On our 440ci C6Z idle with valves: open 105db closed 85db
Titanium Ultimate NPP Weight: 24 lbs
OEM NPP Weight: 52 lbs
Black (PVD) tips are standard with the Stainless Ultimate NPP. Uprgrade to brushed titanium tips is available
