Dyno verified gain of 14.2 HP and 14.8 ft-lbs torque corrected to the crank.Developed in-house on the AWD dynamometer, with a critical ear lent to sound volume and tone character. Featuring the distinctive double walled taper tips in a 3.5"" (90mm) diameter, this system looks fantastic on the car.AWE Tuning exhausts have earned praise from owners and the press alike, due to their unique ""Jekyll and Hyde"" personality. They spend considerable time and effort during development to achieve remarkable civility when idling and at part throttle cruising, while also producing a war-cry wail when full throttle is applied. AWE Tuning exhausts are like bespoke suits: each is hand made utilizing only the finest casing and packing materials, and they command respect without calling unwanted attention to themselves. Sophisticated, refined, and powerful, all at once.Each cat back system features an H-Pipe crossover tube at the front to maximize exhaust scavenging for maximum power, as well as to take a harsh edge off the exhaust sounds. Tubing diameter for the entire system is 2.25"". This is a deep bass tone, no matter how you cut it.A natural progression from a cat back exhaust system is the installation of AWE Tuning High Flow Downpipes to really help the engine breathe.Features:View Install Instructions Here304 stainless constructionDouble walled laser etched tipsH-Pipe for balance and toneLifetime WarrantyPerfect Fitment - Guaranteed This product is for Racing Competition only and is not legal for use in highway or street vehicles or other non-racing competition off-road vehicles.
