Exhaust Downpipes for Audi A4 Vehicles

A free-breathing engine churns out more horsepower and torque, but don’t make the mistake of thinking it depends solely on better air intake. To breathe freely and meet its true potential, an engine also needs to freely expel exhaust gases coming from the combustion chambers. USP Motorsports makes available high-flow downpipes and other exhaust components from top manufacturers to improve exhaust flow.

Below find exhausts from manufacturers including 42 Draft Designs, APR, Assembled by USP, ATP Turbo, APR, B&B Exhaust, Corsa Exhaust, Eurocode, Magnaflow, Milltek, Mishimoto, Neuspeed, OEM Volkswagen/Audi, Racingline, Torque Solution, USP Motorsports and Victor Reinz... more

Installing exhaust downpipes takes no special tools. You can bolt them on yourself, sometimes with help from a bud or two, or hire a mechanic. Pipes ship with proper connectors, including gaskets where needed, nuts and bolts. All are made to match up to stock pipes and connection points. 

Some feature full TIG welding for strength and stainless steel for durability. You’ll get not only more power and response, but also a sweeter exhaust note. Choose from downpipe-catless, downpipe-catted, valueline pipe, heat wraps, gaskets for pipes and manifolds, exhaust studs, nuts, bolts, hangers and clamps.
