Description

APR cat-back exhaust systems personalize your vehicle's looks, sound, and performance. Beautifully hand-crafted T304 stainless steel components adorn the system, with stunning TIG welding throughout. The straight-though brushed finish mufflers smooth the exhaust note to a deep growl, without adding restrictions, while the Helmholz resonator reduces unwanted frequencies. Strong high-quality bracketry and OE-style clamps hold the system steadily in place, making the install or removal a snap—and fitment simple, yet precise.

Additional details:

* Low-profile design, suitable for lowered vehicles
* Larger diameter piping and tips, compared to stock
* No increase in weight, compared to stock
* Limited lifetime warranty
