Bullet Exhaust System

Billy Boat Performance Exhuast has created the most aggressive C5 performance exhaust system to be released - the BULLET! Not for the meek or mild, the Bullet has quickly become the industry standard for a deep, aggressive muscle car sound on the C5. You can see up to 18 rear wheel horse power and 17 foot pounds of torque from the Bullet. With Billy Boat Performance Exhaust's boldest tip style and configuration insure the C5 will scream "muscle car".

Route 66 Exhaust System

Cosmetics on the Route 66 are drastically improved with Billy Boat Performance Exhuast's exclusive quad 4.5" wide and 3" tall, highly polished, rolled edge speedway tips. The C5 Route 66 System creates a distinctive muscle car idle note that emits a true touring performance sound on the highway and will garner an additional 11 rear wheel horsepower.

Purge Resonance Technology for your C5

The Billy Boat Performance Exhaust PRT after-cat system employs exhaust technology unique to the aftermarket. So unique, in fact, it doesn't use a muffler at all. The Billy Boat Performance Exhaust PRT system is simple in design, though more complex in theory, which suggests that you can have a mellow sound at cruising speeds and a sport note when you're tearing up the streets. It allows true straight through exhaust passage under agressive driving conditions, through a mellow sound is emitted at cruising speeds thanks to the unique Purge Chamber. This Billy Boat Performance Exhaust PRT system works purely on physics without mechanical devices to direct exhaust flow.

Using our in-house Dynojet chassis dyno on a 2001 6-speed with a Billy Boat Performance Exhaust PRT system show gains of 12 additional horsepower and 14 lbs/ft of torque. What's cool about the Billy Boat Performance Exhuast PRT system is its decidedly Dr. Jekyll and Mr. Hyde nature. You can cruise down the highway, in overdrive, at extra-legal speeds and be totally unaware of the monster that lurks beneath. Hammer the throttle and the beast is awakened, roaring like AJ Foyt on too much caffeine.

C5 Shorty Headers

Built entirely of T-304 stainless steel, Billy Boat Performance Exhaust Shorty Headers for the C-5 Corvette are direct replacement parts for the factory equipment. Billy Boat Performance Exhuast is the originator of the LS1 shorty header. Longer, equal length primary tubes increase performance and throttle response and large diameter 1.75" primary tubes improve flow. Unlike most header manufacturers who settle for an open collector, Billy Boat Performance Exhaust hand builds each of its 4-into-1 merged collectors for the best performance possible. In addition to a performance increase of 10 rear wheel horsepower, Billy Boat Performance Exhuast's Shorty Headers weigh 15.3 pounds, that is less than half the weight of the heavy OEM cast iron manifolds.

C5 Long Tube Headers

Billy Boat Performance Exhaust has once again taken the Pole Position in the market by developing long tube header systems specifically for the C5 and C6 Corvette. The header design incorporates the correct firing sequence which pairs exhaust ports together for more efficient exhaust scavenging. Dyno testing, utilizing technology previously found in racing applications has shown an increase of horsepower and torque throughout the entire RPM range. This is a true bolt-on header, complete with hardware and gaskets, dedicated to the C5 and now for the C6 Corvette as well. The new 1.75" tube flows seamlessly to a 3", 4-into-1 collector.
