We decided that since we’ve made you guys wait a long time already, we’re just going to skip the whole group buy process and drop the price on our downpipes IMMEDIATELY.
The retail pricing for our JHM 2.5" Stainless Steel Downpipes is $750. But as part of our official release and introduction to the JHM 3.0L program, we’re going to start them off at a limited time introductory price of $695!!! This pricing is LIVE so navigate to our site using the links below to make your purchase!
These downpipes will fit ALL B6-A4 (2002 to 2005) 3.0L V6 cars with Manual or Automatic (Tiptronic) Transmissions.

Why did we go with 2.5" piping diameter? We tested a few different piping sizes (2.25, 2.5, and 2.75) and found that in every configuration - stock ECU calibration with a stock sized (54mm) cat-back, stock ECU calibration with an aftermarket cat-back, JHM Tuned ECU with a stock sized cat-back, and JHM Tuned ECU with a stock cat-back - that 2.5 inch piping diameter provided the best gains in acceleration and high-end power without sacrificing low-end torque.
If you are looking to unlock the potential of your 3.0L V6, these 2.5" downpipes are the key. They are an absolute MUST for anyone looking to get more power out of their car. Our extensive research has proved this point time and time again. When we put our 2.5" downpipes on a stock car, the car was impressive as compared to stock and the increased airflow of the downpipes definitely made the car seem a bit more “peppy”. However, when we put the downpipes on a car with a JHM B6-A4 3.0L V6 ECU Tune on it, the result was amazing. The combination of the increased airflow from the downpipes and the ability of the JHM ECU Tuning to take advantage of that increased airflow completely transformed the power band of the car. The gains in low-end torque were good but the most impressive power increase can be found in the top-end of the RPM range. With the motor breathing more freely and the addition of our ECU Tuning, the 3.0L just keeps accelerating up top!
The biggest gain in power comes from removing the huge catalytic converter complex that Audi has placed right up against the head of the motor, just after the outlet of the exhaust manifold. This inlet is INCREDIBLY SMALL. It’s even smaller than the already tiny diameter of the stock exhaust piping. Look at these photos showing the ID of the OEM downpipe inlet and comparing the JHM Downpipe Inlet to the OEM Downpipe inlet:

This next picture shows both the location and the size of the incredibly restrictive OEM Catalytic Converters. Yes, Audi has actually put two catalytic converters in that small space - the pre-cat and main cat.

Look at the size and location of that cat! This drastically slows down the airflow coming out of the motor and creates heat right at the back of the motor - both of which are bad for making power. By removing the catalytic converter AND increasing the piping diameter to 2.5", we solve both of those issues! Actually, the inner diameter of the JHM Downpipe at the inlet is over 2.5 inches!

Our JHM B6-A4 3.0L downpipes have a reducer at the end of the pipes that will allow you to run these pipes with a few different cat-back setups:
- Stock B6-A4 3.0L V6
- Stock B6-S4 Cat-Back
- ANY Brand X B6-S4 Cat-Back designed to mate up to stock downpipes
In our testing of different exhaust setups and in our experience with cat-backs for the B6-S4, we’ve found that all aftermarket cat-backs neck down to the stock piping size EXCEPT for the JHM-Fast Intentions 2.5 inch cat-back. So, if you have a stock cat-back or pretty much any other aftermarket cat-back, our JHM 2.5" downpipes will bolt right up to your system! Just secure your downpipe to cat-back connection with your OEM downpipe to cat-back clamps. If you need OEM downpipe to cat-back clamps, we sell them in our store. Just search for “clamp 54mm”.
Note: If you are interested in running a full, 2.5 inch exhaust setup, we already have adapters made to connect our B6-A4 3.0L V6 2.5 inch downpipes to most FULL 2.5 inch B6-S4 Cat-Backs (i.e. ones that don’t neck down to stock pipe sizing), including our JHM-Fast Intentions Cat-Back. Call us for details.
We will also be offering a set of 2.5" Stainless Steel Downpipes with High-Flow Cats. These can be found via the link below:

After a lengthy development period, we are excited to finally offer the JHM B6-A4 3.0L ECU Tuning. We went to great lengths to calibrate this tune to get the most out of your 3.0L V6 motor. Our tuning will completely change the performance of your car. You will experience increased and improved throttle response, increases in low end torque, and increases top end power. Our tuning also features our proprietary JHM Launch Assist feature! This is a great assist for those looking to launch their car easily and consistently, without any hassle. NOTE: At this time, we only have a true Launch Assist for manual transmission cars. If you have an automatic/tiptronic car, consider purchasing our TCU tune which features an increased stall to help you get off the line faster.
Our JHM ECU Tuning you will give you noticeable improvements in the performance of your 3.0L. However, if you add our JHM 2.5" Stainless Steel Downpipes ON TOP of the ECU tuning, it will completely transform the power band of your car. If you are looking to unlock the potential of you 3.0L V6, these 2.5" downpipes are the key. Check them out in the Engine and Performance Section. They are an absolute MUST for anyone looking to get more power out of their car. Our extensive research proved this point time and time again. When we put our 2.5" downpipes on a stock car, the car was impressive and the increased airflow of the downpipes definitely made the car seem a bit more “peppy”.

Please click on our product page and read the section “HOW TO GET YOUR ECU JHM TUNED” for information about getting your ECU Tuned by JHM. All ECUs must be sent to JHM at this time. We are working on gaining the ability to flash the B6-A4 3.0L V6.
Our JHM TCU Tuning for Tiptronic Transmissions can be found via the link below:

The JHM TCU Tuning for your Automatic B6-A4 3.0 makes your Tiptronic Transmission shift faster and harder. We firm up the shifts to give a clean and crisp gear change that is faster and firmer than the stock characteristics but still not too abrupt. We feel our JHM TCU Tuning makes the car shift how it should have from the factory. It gets rid of the sloppy and slow slipping of the OEM TCU calibration and replaces it with firm, crisp, shifts. This allows you to get the most out of your Tiptronic B6-A4 3.0L by allowing you to put the power to the ground faster.
Our TCU Tuning not only speeds up the shifting on upshifts JHM also modifies the downshifting characteristics and the behavior in “Tip Mode” to make the car more performance oriented while still being very streetable. We also improve the downshifting as well, we have been told it feels “less clunky”.In our development for the TCU tuning we made a few different calibrations that could make the transmission shift harder, but we found that this made the car feel too much like and old muscle car, and less like an Audi.
When you increase the power of the vehicle, the slipping and sliding of the OEM calibration will prematurely wear out the transmission. While it may be comfortable, the slipping of the transmission means that all of the clutch packs in your transmission are doing more work and slipping more, wearing out faster. The faster and firmer shifts prevent this wear by decreasing or eliminating the slipping.
Similarly to the ECU Tune, the JHM TCU Tune must be completed at JHM. For information on getting your TCU tuned by JHM, go the the product page and read the section titled: “HOW TO GET YOUR TCU JHM TUNED”.

Again, thanks to all of our supporters who have pushed us to release these downpipes, the ECU tuning, and the TCU tuning. We wouldn’t be where we’re at now if it wasn’t for your support online AND your support through purchases of oil change kits, spark plugs, air filters, and short shifters. Thank you for every 3.0L purchase - large or small - it all helps us to continue to release industry leading products for your vehicles.
Please feel free to give us a call if you have any questions!
