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 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". 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!

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 (cut off the 2.125" neck down and adapt as needed)
