Frequently asked questions
Do C8 RS6 downpipes fit the RS7?
Yes, several do. The IRL MaxFlow, Spool race and STRATEC catless pipes are listed for both the C8 RS6 and RS7, and the Spool pipe also lists the D5 S8. The earlier C7 RS6 4.0T uses different parts with their own STRATEC catted and catless options.
Do Urus downpipes fit the RS Q8?
Some do. The IRL MaxFlow race and Spool downpipes list both cars, and Spool also lists the Porsche Cayenne Turbo. Check the years: the IRL pipes list the Urus 2019-2021 and RS Q8 2020-2021. See our 4.0T V8 downpipe guide.
Are there catted Audi downpipes?
Yes. STRATEC sells catted pipes for cars including the B9 S4/S5, RS5, Q8 3.0T, SQ8/RS Q8 and C7 RS6, plus an OEM-style catted B9 A4/A5/Q5 2.0T pipe. IRL offers its B9 and C8 RS6/RS7 MaxFlow pipes in race, 200-cell or 400-cell.
How do I pick the right pipe for my Audi?
Match the engine and generation, not just the model: B8 and B9 cars, B9 and B9.5 2.0T cars, and 8V and 8Y RS3s are listed separately or together depending on the brand. Read the fitment list on the listing, and we are happy to check your VIN.
Do I need a tune to run an aftermarket downpipe?
Plan on one. Most downpipe listings recommend a supporting tune, several say a check-engine light may occur without one, and the brands quote their gains with proper tuning. Talk to your tuner before you order so the software and hardware match. Our catless vs catted guide covers the details.
Are catless downpipes legal on the street?
Catless and high-flow downpipes and other emissions-related parts are intended for off-road and competition use and may not be legal on the street where you live. A high-flow converter is not the same as a certified replacement part, so check your local laws and inspection rules before you buy or install one.
