Description Fitment Guide Installation Instructions
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.

  • T304 stainless-steel construction

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.

Clamps

Our system uses OEM-style low-profile slip clamp. Our clamp selection allows the system to sit high in the exhaust tunnel, as is favored by lowered vehicles, with ultimate compatibility no matter what midpipe you may have. Each connection point is strategically placed to ensure the system has minimal opportunity to rotate during install or during years of heavy driving. Finally, because there are no flanges or swedges on the pipe, fitting the system to the factory midpipe or others is a breeze. There’s no cutting, welding, or glaring compatibility issues, and there are no gaskets to replace.

Compatibility

We’ve designed our system to be 100% bolt-on. There’s no cutting, welding, or finagling to get the system to fit. It simply bolts on for use with the factory midpipe.

(Go Fast Bits) diverter valve plus install

Installed this GFB diverter valve to eliminate the OEM plastic one all together that are prone to failing. I also spent the little more instead of rebuilding the bottom of the OEM that GFB offers but doesn’t clear all cars. BOV option (any brand) can cause car to have lights & running rich issues if not tuned asap so this was the best option for me to pair with my neuspeed intake. Plug and play harness & works great ! Can tell has less slop from day to day traffic & daily driving.

Good Intake for the price !

This intake sounds amazing at low rpms ! Definitely using some more gas cause it’s hard to keep foot off the throttle lol. Was a tight fit on an 2014 Audi TT Quattro S Line. Engine cover does touch against the intake tubing but fits overall pretty well.

Some slight modifications to the car and the cold air heat shield was needed but otherwise it fit great. Can really hear her breath now!

Very nice!

Love my new side markers - very clean looking and unique in how they flash when turning left or right. The only suggestion I’d make is provide instructions for both installing them and for being very careful with the wire once you disconnect the old light housing Left side went in ok, but I lost the right side into the fender black hole which required me to remove the tire and unscrew most of the lining so I could find the wire!

2017 GTR - Worked Great and Fast Shipment

Needed the mid-pipe fast and was concerned about it coming from Canada, but it spent less than a day in customs. Ordered Wed afternoon. Got it the following Tuesday mid-day UPS Global. As some told me on a GTR forum, it makes the exhaust sound a little quieter, which is fine with me. Still sounds great at full turbo PSI. Price was less than 50% of other comparable products, so great value all around.

Good upgraded replacement for worm factory part

The bushing fit perfectly and I did notice a firmer feel when I used my car at an Autox event.
I had the whole front subframe out, easy access to the steering rack while I was in there.

New tips, same as the old tips

At 16-years in, the originals had become pitted and scruffy. These new OEM ones look, well, like new! Really tidies up the car's look.

TB Spacer was Great

Ordered a throttle body spacer nearly a year ago from CTS Turbo. TT Stuff reached out once this replacement became available, and I had it in a couple of weeks. Highly recommend working with these guys. Email replies were never more than a day away.
