Product Details

Description

Unitronic is happy to release their Performance Downpipes for the 2020+ C8 RS 6 and RS 7 equipped with the 4.0TFSI EA825 (DJPB) engine. These downpipes are a direct bolt-on upgrade designed to optimally eliminate unwanted restrictions in the factory downpipes, reduce turbo lag and enhance the exhaust note while utilizing a 6” 400cpsi ultra high output catalytic converter, designed in partnership with Unitronic, from our emissions partners at Global Emissions Systems Inc (GESi).

GESi’s GEN2 ultra-high output UHOX catalytic converters were designed in conjunction with Unitronic for several 2017+ Audi and Volkswagen® applications, rated at up to 1200HP by GESi. Paired with Unitronic Stage 2 Performance Software and other supporting bolt-ons, these Performance Downpipes help yield up to 819HP / 760LB-FT.

The large 6" catalytic converters provide exceptional flow and greatly enhance the thunderous sound of the turbocharged 4.0TFSI engine. The smooth post-cat stainless steel transitions lead into dual 4.5" T304 stainless steel tubing, terminating at the factory 3-bolt mid-pipe flanges to ensure a seamless direct bolt-on fitment.

One key development area for Unitronic Engineers was the catalytic converter on these Performance Downpipes. While working closely with GESi through several iterations of their G-Sport Emissions Systems Catalytic Converters over the years, our goal once again was to ensure this product would satisfy our compliance demands while fulfilling Unitronic's performance-related goals. The team quickly opted for dual GESi 6" UHOX converters for these Performance Downpipes, which met the requirements for the C8 4.0TFSI while being rated for a massive 1200HP.

To take full advantage of these all-new Performance Downpipes, Unitronic Stage 2 ECU Software is now available for the C8 RS 6 and RS 7. With testing and validations completed, power outputs are increased by up to +219HP / +166LB-FT with Unitronic Stage 2 93octane/98ron Performance Software for a maximum of 819HP / 760LB-FT. This software upgrade is entirely compatible with our UniCONNECT+ cable, empowering Clients to tune their vehicles directly through the OBD-2 port within minutes from the comfort of their homes or garage.

    Not as direct bolt-on as advertised for the 2017 TT...

    Needed to cut 2.5 inches off of both the supplied reducer and muffler pipe to get this to fit correctly. Other than that it looks great...not sure how I like the sound yet...

  • Review shared from Unitronic Gen 3 3" Downpipe - w/Cat (1.8/2.0 TSI FWD)

    I ordered this Downpipe in a hurry as I had already order my Unitronic Stage 2 tune, and had bought a used downpipe that ended up having a leak. I installed this downpipe in my driveway with hand tools in about 3 hours, by myself. It's a straight forward installation, and the quality of Unitronic's downpipe is excellent! I love my Jetta GLI being at Stage 2 power/torque and this downpipe sounds great at cold start and in upper RPM's; though it tough to hear over the turbo spooling!

    Unitronic threw two extra 3" sealing rings into my box as well, which was nice as they are just thin aluminum. This pipe fit perfectly and did not require any custom modification to install.

    Enthusiast of style and speed

    Let's start with the sound..... Just incredible. Deep and refined.
    Having seen many exhaust options from the aftermarket, I truly believe that the fit and finish of the Unitronic high-flow cat and downpipe are of the highest quality. Being an aircraft mechanic I can appreciate the addition of v-band style connections that are a proven solution for joining piping being both leak free and secure.
    Now I'm ready for APR Stage II

    Vw gti

    Put this on my 2009 gti tsi. I could tell the difference from stock. It's a nice down pipe and was easy to install. Took around 3-4 hrs on installation. Running it with stock muffler. Worth the money.

    12 VW GLI Gen1 2.0T

    Great product from Unitronic, Hardest part was getting the top bolt closest to the block on the factory downpipe. Loosened it from the top side using a 16mm box end wrench and then used a 16mm socket with an extension fend in from the driver side near the master cylinder to finish taking the nut off. I would also recommend picking up a factory turbo gasket, i picked one up at the local parts store for $10 bucks. Unitronic downpipe was easy to install once the factory stuff was out of the way. Have the stage 2 tune so no CEL issues and noticed a big increase in power and smoothness from the stage 1+.

  • Review shared from Unitronic 3" Downpipe - FWD w/Cat (15-21 GTI, 19+ GLI)

    The downpipe arrived and the quality is awesome. Zero fitment issues, OEM cat placement, and v-band clamps make the installation super easy.

  • Review shared from Unitronic 3" Downpipe w/Cat (16-18 Jetta 1.4T)

    2017 Jetta 1.4T

    Great downpipe! I also have a cold air intake installed. After installing the downpipe the intake is now louder. The downpipe did not make much noise difference itself with the stock exhaust but there is a slight difference. However, there is a great difference in power and torque. It does pull a CEL without the stage 2 tune for the O2 sensors but the tune clears that. I would definitely recommend this product.

    Great add on!

    I just installed this on my 2016 last weekend. Install was a pain. I wouldn’t do it again but the finished result is amazing. I had the 1+ tune before and the stage 2 with this pipe is quite a bit quicker. The sound is a lot meaner. Can’t wait to surprise some people at green lights!

    3” Uni Downpipe

    Bought this downpipe/mid pipe kit and love it. Coupled with the Uni intake and stage 2 tune my car feels twice as fast. Cannot believe the torque gains from the tune. But the exhaust I love because it’s not too loud. I’m not one for loud exhausts and I feel this pipe fits right in the middle. Super easy to install

  • Review shared from Unitronic 3" Downpipe - FWD w/Cat (15-21 GTI, 19+ GLI)

    Great gains, great engine response

    Installation was a cinch. Getting the stock downpipe off, however, was not. There was zero room to work with! It helps to have a spotter on top while you work underneath the car. Performance gains are very nice over stage 1. It now pulls all the way to redline, and turbo lag is much less apparent. Also, looks good, but unassuming, with a nice brushed stainless finish. Since there's no Unitronic logo all over the top half, it looks almost stock from the engine bay. Welds are nice. The Unitronic stamp on the subframe mount is a nice touch. The excellent v band system means no exhaust leaks. This is worth the price for the excellent fitment.

  • Review shared from Unitronic 3" Downpipe - FWD w/Cat (15-21 GTI, 19+ GLI)

    Easy install, amazing gains

    Getting the factory downpipe off wasn't easy, but getting this one installed was a piece of cake. The gains were substantial and immediately noticeable. On my 2019 Jetta GLI, the sound isn't much louder than stock, to be honest. I was expecting louder, but I still have the stock catback. Make sure you have a spotter to assist in removing the factory downpipe.

    Unitronic 3” Downpipe

    I couldn’t be happier with the quality and most importantly the fit of the Unitronic Downpipe. The install was about 4 hours from start to finish. I also went from Stage 1+ Unitronic ECU tune to Stage 2 after the Downpipe was installed. The increased performance is the largest difference I’ve seen or felt out of all the modifications I’ve done so for to my 2013 Mk6 GTI. It really is like driving a different car. This Downpipe is without a doubt of the highest quality and, as I previously stated, the fit is “OEM good”. Thank you Unitronic and Moddedeuros!

    Took a while but i got it done

    I purchased the Unitronic Downpipe for my 2013 Volkswagen CC Sport , it took me around 4 hours to install. not that it was hard just my first time doing something of this nature. everything went smooth until i had to connect the down pipe to my stock catback exhaust the adapter it comes with to allow you to do that was to long so i had to cut my exhaust about a inch and a half for it to fit and allow me to use the stcock clamps it came with .

  • Review shared from Unitronic Gen 3 3" Downpipe - w/Cat (1.8/2.0 TSI FWD)

    Very impressed

    Just want to say I am very impressed with this downpipe. It took the shop hour or hour and half to put on. Had enough clearance, and the shop guy said it went very smooth. Also no check engine light so fair, so that made me happy.

    Still great product

    After a few hours of driving and no check engine light, I guess the computer felt something different and has thrown the light 😂😂😂

    Car Enthusiast

    At first It was a little loud, Atleast to my exceptions considering it was Catted, but after tying my car to the stage 2 Unitronic burble tune I fell in love instantly. The car sounds great, burbles likes crazy (which I guess depends on ur preference) but I have zero complaints. Even if you want to run the stage 2 file without burbles you will have very moderate burbles but it’s not to complain about. Would definitely buy again and very happy with the way my A3 sounds. Don’t fall for the catless gimmicks because this sounds just as good but doesn’t case a gas smelly cabin and you can run through state inspection just fine.
