APR Tuned Stainless Steel Catback Sport Exhaust Audi A4 B8 1.8T 6spd Quattro 04-05

APR's B6 A4 Exhaust is a complete stainless steel, mandrel bent, cat-back exhaust. On an A4, the catalytic converter is bolted to the turbocharger and then the exhaust begins with the downpipe. Unlike most other aftermarket exhausts, the APR exhaust includes a 2.5" downpipe. APR has two different exhaust systems available for the B6 A4, the Stealth and the Sport. These systems are a complete package replacing all of the tubing from the OEM catalyst to the polished stainless tips that are acid etched with the APR logo.

The APR Sport exhaust is for the no-compromise enthusiast that wants maximum gains and doesn't mind a little extra exhaust note. This system is similar in construction to the Stealth exhaust, but deletes the center muffler.

With TIG welding, fully stainless construction, and CNC'ed hangers, you will not find a higher quality system on the market. APR is so confident in the construction of the B6 A4 exhaust it comes with a full lifetime warranty.

APR’s B6 A4 exhaust systems have been designed to have flow rates more then sufficient for even the highest levels of performance.
