The Tubi Style 993 Turbo Mufflers provide a much needed boost to the 3.6 liter's otherwise tame exhaust sound. The specially designed canister provides the most uninterrupted exhaust flow possible without any compromise to drivability. The sound is aggressive enough to compliment the car's outstanding performance without any excessive droning or cabin noise, making it easy to blend in under normal driving or highway cruising. The increased flow relieves back-pressure on the turbochargers allowing them to operate more efficiently and generate less damaging heat.
