Product Description
The Rev9 CB-309A is for Q50 3.0T owners who want a more aggressive exhaust note without replacing the entire factory exhaust. This dual 2.5-inch axleback takes the place of the rear factory exhaust section and finishes with large 4-inch double-wall stainless tips.
It is a simple way to make the VR30DDTT sound more present without adding a full catback system. The axleback layout keeps the rest of the factory exhaust in place, while the stainless construction, mandrel bends, TIG-welded joints, and CNC-machined flanges give it the hardware needed for a direct-fit installation.
Great way to add an exhaust without spending a lot of money you would with a full catback.
Check your area to ensure you can run a muffler delete on your car.
Before You Order
This is a muffler-delete axleback, so expect a substantial increase in exhaust volume compared with stock. Sound level will vary with the vehicle's existing intake, downpipe, and mid-pipe setup. Inspect the factory exhaust hardware before installation, and confirm your local sound regulations before modifying the exhaust.
