Looking to improve exhaust flow while still maintaining a refined exhaust note. Our muffler version axleback exhaust system features dual muffler canisters. Each has 2.5" inlet, straight through muffler canister design, and large dual 4.5" double wall tips. The high flow oval style muffler canisters include two types of internal packing to help with sound suppression and give a deep exhaust note. 

If using just the axleback kit, this product is best suited for the 2014-2015 Q50 with the 3.7L NA engine (VQ37VHR).
When using only the axleback kit on a 3.0L twin turbo engine (VR30DDTT), the sound is similar to stock. Using the axleback kit WITH midpipe kit and Y-pipe kit yields a high flow catback system that has a deep and not overly loud exhaust note.
