Exhaust Downpipes for Audi, Volkswagen VW, BMW & Porsche 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

It’s not uncommon for aftermarket down pipes and cat-free pipes – those that lack a catalytic converter, technically speaking for racing applications – to add 20 to 30 horsepower and ft/lbs of torque at the wheels. To remain street legal, you need a catalytic converter, of course, but models with free-flow cats also give noticeable power increases. Software upgrades ensure that a high-flow exhaust can unleash the most untapped power.

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 pipes have pre-drilled and machined holes for oxygen sensor spacers (extenders) so that your check-engine light won’t pop on.

The pipes we sell are less restrictive than stock pipes. 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, free-flow catalytic converters, complete downpipe, high-flow cat, testpipes, cat eliminator test pipe, 2-into-1 pipe with high-flow catalytic converters, downpipe with testpipe, valueline pipe, heat wraps, gaskets for pipes and manifolds, exhaust studs, nuts, bolts, hangers and clamps.
