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.
This is strictly for a partial payment of the pre-order.
Pre-order is fully refundable, no questions asked.
Header only pre-orders will likely ship early December. Header + Ultimate NPP will ship in early January
- 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 chrome (PVD) tips are standard with the Stainless Ultimate NPP. Uprgrade to brushed titanium tips is available
