Overview
The factory Downpipe on the B8/B8.5 S4/S5 3.0T carries a restrictive pre-catalyst at the front of the exhaust system. This catless Downpipe removes that restriction entirely — opening up the exhaust path and giving the supercharged V6 a sharper, more immediate response under load.
- Removes the primary restriction in the factory exhaust path
- Sharper supercharger response under load
- More defined exhaust character on tuned applications
- Stainless Steel construction for longevity
Driving Experience
The B8/B8.5's supercharged V6 doesn't rely on spool the way a turbo does, but exhaust restriction still costs it — every bit of back pressure removed from the front pipe shows up as a sharper, more immediate response under load. This is the foundation piece for everything that follows on a tuned build. Note: verify your specific model, year and build variant before ordering, or message us your rego/VIN and we'll confirm it for you. What's.
