What's Included
- 1x AWE 3015-42660 Touring Edition axle-back exhaust system
- 4x 4.5" double-walled slash-cut chrome silver tips (individually adjustable, AWE logo stamped)
- Hardware and Accu-Seal clamps for installation
AWE 180 Technology: Drone-Free Sound
The single biggest frustration with high-flow exhaust systems on LS platforms is drone at highway cruise RPM. AWE's patented 180 Technology addresses this at the engineering level, using tuned reflection chambers inside the muffler body to cancel the specific frequency range that causes cabin resonance. The result is an exhaust that is aggressive at wide-open throttle and civilized at cruise, not a compromise between the two. 3015-42660 uses this same technology, making it genuinely daily-driver friendly on your C6.
Performance Gains
AWE 3015-42660 delivers dyno-proven power improvements over the factory exhaust system. Gains vary based on the mid-pipe used:
| Mid-Pipe Configuration |
Peak HP Gain |
Peak Torque Gain |
| Stock factory H-pipe |
Up to +16 HP |
Up to +17 lb-ft |
| AWE X-Pipe (sold separately) |
Up to +21 HP |
Up to +22 lb-ft |
The AWE X-Pipe is a separate purchase. 3015-42660 is compatible with the factory H-pipe out of the box and delivers meaningful gains without any additional modifications.

Construction and Build Quality
AWE hand-builds 3015-42660 in-house at their facility in Pennsylvania, USA, using American-sourced T304L stainless steel tubing at 0.065" wall thickness. CNC mandrel bending ensures tight, consistent bends without flow-restricting kinks. The over-axle pipes feature a 2.5" inlet to mate with the factory C6 mid-pipe, then step up to 3" diameter through the rest of the system, giving you a measurable flow improvement over the stock 2.5" axle-back. Tips are individually adjustable to allow precise centering in the rear bumper cutouts.
Installation Overview
AWE 3015-42660 is a direct bolt-on installation requiring no cutting, welding, or tuning. Installation time is approximately 1.5 hours on a lift with basic hand tools. The system uses Accu-Seal clamps for leak-free connections. Anti-seize is recommended on all clamp bolts. A professional alignment of tips in the rear bumper cutouts is recommended before final torque. All factory hangers are reused. No Check Engine Light is guaranteed with correct installation on the compatible models.
Warranty
AWE backs 3015-42660 with their Lifetime Exhaust Warranty and a Perfect Fitment Guarantee. The Lifetime Warranty covers defects in materials and workmanship for the life of the product on the original vehicle. As an exhaust and performance component, this warranty is also subject to the disclosure requirements of the Magnuson-Moss Warranty Act, which ensures consumers receive clear warranty terms for automotive parts sold in the United States.
