The APR Catback Exhaust System personalizes your vehicle's looks, sound and performance. Beautifully hand-crafted T304-stainless-steel components adorn the system with stunning TIG-welding throughout. Our straight-through brushed-finished mufflers smooth the exhaust note to a deep growl, without adding restrictions or rasp. Strong high-quality bracketry and OEM-style clamps hold the system steadily in place, making the install or removal a snap, and fitment simple, yet precise. Dual 2.5" mandrel-bent exhaust paths provide an ultra-smooth path, steadily feeding exhaust gasses out of the quad exit system, while looking tidy from under the rear bumper. Our cast valve housings enable the vehicle to be fitted with the factory electronic valve actuators, retaining OEM valve operation for variable sound levels.   Finally, our 170x112mm ovalized diamond black exhaust tips finish the system, adding a classy RS-inspired touch to the rear of the vehicle.

System Overview

The factory exhaust system starts life as a dual pipe setup but then converges to a single pipe before entering a suitcase style muffler. Our system uses dual 63.5mm piping with no mid mufflers or resonators, and continues all the way to our large sound absorption rear muffler. The cross sectional area of our dual setup is 26% larger than stock! There the system splits to a quad 63.5mm design. Internally the valved path is straight through with no muffling, while the unvalved path is perforated for sound level reduction. This exits the rear into a pair of 170x112mm diamond black exhaust tips that look menacing from the rear of the vehicle.

MUFFLERS

The mufflers are responsible for tuning the exhaust note and do so without adding unnecessary restrictions to the system. Each unit features a straight-through perforated tube that’s tightly wrapped with stainless steel and fiberglass material. The mufflers have a beautiful brushed finish, and are tucked high in the exhaust tunnel, making them perfect for lowered vehicles.

EXHAUST VALVES

Our system features two valves that allow control of the volume of the system via the factory exhaust valve actuators. In doing so, the system can go from tame to aggressive instantly! Unlike pneumatic systems, and other common valves found in the market today, our system maintains identical OEM operation all the way down to the factory valve actuation angles. Furthermore, the system is fully compatible with exhaust remotes, allowing end users to manually open the system at the click of a button. We cast the valve housings out of T304 stainless-steel. Internally the system uses CNC-machined T303 components and brass bushings, which have stood up to our extreme torture testing. All necessary hardware is welded into place and is designed to combat heat and vibration for years to come.

BRACKETS

Our brackets ensure a strong and precise fit, every time. With our design, you’ll never need to worry about the brackets sagging and losing their shape over time, or the post slipping out of the hangers. The brackets are rigid, exact in their position, fit snugly in place and are made to stand the test of time.

TUBING AND WELDS

We use T304 stainless steel tubing throughout. We brush and de-burr all pipes, use mandrel bending techniques to ensure the pipes keep a constant diameter throughout, and use argon-back purged TIG welding for a strong and attractive weld.

TIPS

Our 170x112mm ovalized exhaust tips upgrade the rear of the vehicle. The RS-inspired tips tuck nicely into the factory valance, gently following the valance’s curves and demanding all the right attention in all the right places. We etch a small and discreet APR logo onto the top of each tip, and we tig weld the tips into place.
