Billy Boat Performance Exhaust has once again taken the lead by offering a cat-back exhaust system for the Mazda RX-8. Mandrel bent for a smooth and even exhaust flow, this 2.5" system produces an average of 12 HP and 7ft. lbs. of torque at the wheel. Manufactured from 100% stainless steel tubing, the exhaust system for the Mazda RX-8 features machined billet hangers, a combination of MIG and TIG welding and 3/8" stainless steel flanges for durability and precision fit.
Using modern flow technology and our proprietary muffler design, each B&B system is custom-tuned to match its application - resulting in the best possible performance gain and sound quality combination. This free-flowing and light weight cat-back exhaust system is designed as a direct bolt-on replacement for the restrictive factory exhaust and requires absolutely no modifications to the vehicle or the product installation. In addition to improving the performance and sound of the Mazda RX-8, the fully-polished muffler and 4" double-wall tips offer distinctive style and an aggressive look!
