Rev9 Exhaust for Audi R8 Type 42 4.2L V8 / V10 (2008-2015) 2.75" or 3" Catback Valved Controlled Titanium

The Rev9 Titanium Valved Exhaust lineup for the Audi R8 Type 42 transforms both the 4.2L V8 and 5.2L V10 models into the kind of supercars that sound every bit as exciting as they look. Available in both Standard Sport Muffler and more aggressive Track Edition configurations, these valve-controlled titanium cat-back systems are designed to deliver the best of both worlds — refined and controlled during normal cruising, then brutally exotic and race-inspired once the valves open and the revs climb. The 4.2L V8 systems utilize freer-flowing 2.75-inch piping with an X-pipe merge section for smoother exhaust scavenging and a sharper exotic V8 tone, while the larger 5.2L V10 setups step up to full 3-inch piping for maximum airflow and an even more intense high-RPM supercar scream. Whether you prefer the more balanced personality of the Standard Edition or the raw aggression of the Track Version, both dramatically improve throttle response, exhaust flow efficiency, and overall driving excitement.

Constructed from lightweight titanium with mandrel-bent piping and precision TIG-welded craftsmanship, the Rev9 exhaust systems help reduce overall exhaust weight while delivering a sharper, cleaner, and more motorsport-inspired sound profile compared to the restrictive factory setup. The valve-controlled design allows the R8 to remain civilized enough for daily driving while still unleashing the full exotic soundtrack enthusiasts crave during spirited acceleration, canyon runs, or track-focused driving. Rev9 has earned a strong reputation among performance enthusiasts for delivering aggressive styling, premium-inspired sound, and impressive fitment quality without the extreme pricing often attached to exotic car exhaust systems. If your Audi R8 still feels too quiet or too refined from the factory, the Rev9 Titanium Valved Exhaust lineup finally gives the car the raw personality, lightweight performance feel, and spine-tingling supercar soundtrack it was always meant to have.
