Please PM an Administrator for clarification or permission BEFORE starting a thread or listing a business in your signature. Audits are randomly done and bans and citations will be given to violators of this rule. Each citation is reviewed on a case-by-case basis by the site administrators and moderators.

    Violating vendors of the rules below may receive a forum ban.

    The technical threads have become much more argumentative lately. Although this forum is relatively new, members have approached me regarding the direction some threads seem to head. As usual, posts will be reviewed on a case by case basis.

    When a thread involves a discussion regarding a particular product or company that you may not be in support of, you are expected to post responsibly/maturely if you choose to comment in such a thread. Failure to do so and you will be subject to infraction and/or ban.

    In regards to the ban: The initial ban might be for two weeks, followed by a chance to come back to the forums with a better attitude. If you choose not to change the intent of your post, then you will be permanently banned.
    Simple as that.

    Take care and enjoy the forum.

Stupid question.
I had my tune recently tweaked by my tuner dealer and they reset my passcode to 0101. How do you input a "0"? I'm assuming you just perform the sequence to register without pressing the Set button as there is no value. However this hasn't worked at all for me. Any idea?

Thanks.

I noticed your specified boost and actual boost are very close values. Are they suppose to be like this? When I logged with APR Mobile, the Specified boost was always 4-8 PSI higher, is this normal?

The Audi R8 red plugs. I believe they go for $80 total. I've had them since I went stage 1 like 4 years ago and never had an issue. Now I'm stage 2 since a year ago and no issues.

Those APR figures imo are showing that WG working a lot harder than it needs to.

Do ya mind expanding a bit? Why would you think the waste gate is working harder?

I can try and post some logs with the waste gate & N75 as well. What would result in the WG working to hard?

I posted a thread not too long ago on WG spring pressures, the stock spring is too weak, and guys who use the aftermarket WGs can run the same boost levels at 40% less. A wastegate spring should be right around half of what your max boost is, that's the general rule of thumb.

Hey all! Apr 2.4 tuned here. 3" downpipe with high flow cat and injen cai. Getting low 9s 9.13 - 9.19s in the 8th official track timeslips using the 93 octane tune.

Question about catch can maintenance. What should I use to clean the can and what should be the frequency that I clean it?
Also it says not to fill it over halfway. What is the liquid capacity of the catch can?

Passed Driver's Ed
Arin@APR could you tell me APR K04 v3.1 software for CAWA motor (06J 906 026 AB) does use data from tiguan lambda sensor? It is not wide sensor if it is important. If yes, how this sensor can be checked or what mileage it should be replaced?
Also readiness code for lambda should be passed or not?

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 muffler smooths the exhaust note to a deep growl, without adding restrictions, rasp or drone. 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. A cast 3” to dual 2.5” rear splitter creates an ultra-smooth transition, steadily feeding exhaust gasses out of the system, while looking tidy from under the rear bumper. Finally, removable 4" polished slash-cut exhaust tips finish the system, adding a classy motorsport-inspired touch to the rear of the vehicle.

System Overview

Our exhaust system uses larger piping compared to the factory exhaust system, yet weights several pounds less. We use 3" OD piping, which then splits to a dual 2.5" design. The factory system uses 2.5" piping, which reduces to 2.25" before splitting and reducing fruther, greatly diminishing the overall diameter of the system. Finally, our system’s 4" exhaust tips dwarf the factory tips, giving the rear of the vehicle a sportier look.



Mufflers

The mufflers are responsible for tuning the exhaust note and do so without adding unnecessary restrictions to the system. The muffler 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.



Axle-Back Components

We cast the axle-back splitter to maximize the system’s performance by keeping exhaust velocity high and back pressure low. This is accomplished by gradually splitting the system from a single 3” pipe to dual 2.5” pipes. The organically shaped casting allows us to make this transition gradually as to not disturb the flow of gasses. Furthermore, as this component is visible from the rear of the vehicle, we made sure form matched function with a beautiful surface finish, TIG welding, unique bracketry and brushed, mandrel bent tubing.



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

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 polished slash-cut 4” exhaust tips upgrade the rear of the vehicle dramatically. The motorsport-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 laser etch a small and discreet APR logo onto the top of each tip, and we use T304 stainless Torca AccuSeal clamps that bolt on with ease with hardware that rotates out of sight. Lastly, since the tips are removable, you can upgrade to any one of our optional tip designs at any tim



Clamps

Our system uses OEM-style low-profile slip clamps and T304 stainless-steel Torca AccuSeal clamps for the exhaust tips. 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 Race DP you may have. The clamps make for easy swapping of the exhaust tips, and slide out of the way to make adding or removing the optional front muffler easy. Each connection point is strategically placed to ensure the system has minimal opportunity to rotate during install or during years of heavy driving.



DP Compatibility


We’ve designed our system to be direct bolt-on with the APR Race DP. The included reducer is for use with the factory dp.



Created In-House

Our exhaust systems are proudly designed, developed, assembled and quality controlled in-house at the APR 78,000 sq.ft performance campus in Opelika, Alabama.
