Look at the size and location of that cat! This drastically slows down the airflow coming out of the motor and creates heat - 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!

These are the same style downpipes that were featured on our record setting, "JHM3LTR", our in-house B6-A4 3.0L V6. See them in action in the video below. It also provides some great sound clips of different exhaust configurations! 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
- Full 2.5" for JHM-FI B6-S4 Cat-back In our testing of different exhaust setups and in our experience with cat-backs for the B6-S4, 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 do not neck down to stock pipe sizing), including our JHM-Fast Intentions Cat-Back. Call us for details.** INCLUDES:
- 1x Pair of JHM 2.5 inch Downpipes NOTE: We recommend replacing your exhaust manifold to downpipe gaskets every time you remove your downpipes from the exhaust manifolds. You can purchase these in the same section as you found this product in or by searching for "3.0 exhaust manifold gasket". FITMENT:
- ALL quattro B6-A4s - 2002 to 2005 - with the 3.0L V6 (Manual or Automatic Transmission) THESE DOWNPIPES ARE FOR OFF-ROAD USE ONLY!!!

Just recently had these installed on my car and I love them. My car now has much more noticeable power and it's sounds amazingly aggressive with my non res Milltek fatback exhaust. It turned heads every time I punch the gas.
I highly recommend these for anyone with a 3.0 as it gives you the long awaited power the 3.0 needs. My car is no longer as what people would call a 3.0 slow (Posted on 4/18/2014)
