Introducing the JHM B8-S5 4.2L FSI V8 2.5" Stainless Steel Race-Pipes!!!

NOTE: Most of the industry refers to this style pipe as a "Test Pipe" we call it a race pipe to further clarify this product is for Racing Competition only and is not legal for use in highway or street vehicles or other non-racing competition off-road vehicles. By purchasing this product you acknowledge its intended use.

After rigorous testing and prototyping since we acquired our in-house 2008 S5, we are pleased to announce the release of our 2.5" Stainless Steel Race-Pipes for the B8-S5 with the 4.2L FSI V8.

As the pictures above show, the OEM cat-pipes are extremely restrictive and limit the amount of power this motor can produce. Our JHM 2.5" race-pipes are a must have item for any S5 4.2L V8 owner looking to make serious power from their vehicle.

These pipes were featured in the record setting runs of our in-house B8-S5 4.2L FSI V8:

J-BUNG FOR SECONDARY OXYGEN SENSORS: Our JHM J-Bungs have been designed to help with installation of the cat-pipes and replacement of the secondary oxygen sensors. They are NOT designed to prevent the fault codes and/or check engine light (CEL) that may show up after installing these pipes. Due to the stricter emissions requirements on the newer cars, the ECUs and oxygen sensors are becoming more sensitive to changes in downpipes. Prevention of the CEL is best handled in properly tuning the ECU, which is a product we offer for the S5 with the 4.2L V8 FSI.

FITMENT: These race-pipes fit ALL B8-S5s with the 4.2L V8 FSI motor, manual or automatic. We have also designed these race-pipes to work with both stock and other "brand-x" aftermarket downpipes. So, our JHM 2.5" Stainless Steel Race-Pipes will work with both your stock downpipes AND your aftermarket downpipes (if the downpipes were built for stock location, OEM cat-pipes.

NOTE: These pipes were designed on a Left Hand Drive vehicle. We have had some Right Hand Drive customers mention that they had to make a slight indentation in the pipe to clear the steering shaft and linkage. Please take this into consideration when ordering.

Note: JHM works hard to make all fitment charts as accurate as possible please read the product description to make sure this is correct for your vehicle.
