FAQ
Will this exhaust system work with my factory exhaust?
Yes. Factory 2-3/4" reducers are included for connection to the factory exhaust without any cutting or welding required.
Will this work with the Speed Engineering 3" X-pipe kit?
Yes, but it requires modification. 3" connection pipes are included for use with the Speed Engineering X-pipe kit. To use them, the inlet reducer must be cut off the exhaust system and the 3" connection pipes welded in place for proper installation.
Does this system work with the factory Active Exhaust (NPP)?
Yes. This exhaust system includes mounting locations for the factory active exhaust motors, so NPP-equipped C7s can retain their active exhaust hardware.
What muffler design does this system use?
This system uses a straight-through and baffled oval muffler design for an aggressive exhaust tone with optimized flow.
What tip size does this system use?
Dual 4" double wall tips are included.
What is the difference between this exhaust system and the C7 X-pipe full kit (25-1044 or 25-1068)?
The X-pipe kits connect your longtube headers to the axle-back location. This system IS the axle-back — it mounts at the rear of the car and connects to either the factory exhaust or the X-pipe. These two products complement each other for a complete front-to-tip header and exhaust system.
What material is this exhaust system made from?
304 natural stainless steel with mandrel-bent tubing and TIG-welded construction. 3" stainless band clamps and dual 4" double wall tips are included.
Is this exhaust system street legal?
No. This is a race-only product intended for closed-course competition use only. Installation on a street-driven vehicle may violate the Clean Air Act (42 U.S.C. 7522(a)(3)).
⚠️ Race Use Only: This product is manufactured and sold for installation on vehicles used solely for competition. Once installed, the vehicle may not be used, registered, or licensed for use on a public road or highway. Installation on a street-driven vehicle may violate the Clean Air Act 203(a)(3), 42 U.S.C. 7522(a)(3).
