Hummer H1 Performance Exhaust System

Billy Boat Stainless Steel Performance Exhaust System for the 1996-2000 Hummer H1

Since 1989 Billy Boat Performance Exhaust has designed, tested, and manufactured the highest quality stainless steel exhaust systems available. Originally specializing in Porsche 911 performance exhaust systems, oil coolers, and intercoolers, B&B then branched out to design and manufacture high performance exhaust systems for most every performance vehicle on the market. This Hummer H1 after-cat system is purely indicative of the quality build, fitment, performance, exhaust note, and style that has made Billy Boat one of the industry leaders on exhaust systems. A great, easily installed, and instantly noticable upgrade modification for any Hummer H1 out there, and something every owner would be proud to have!

Available both with the Billy Boat stainless steel double-wall muffler, or without it. Note, the system without the muffler will be a much louder and more agressive sounding exhaust system, producing a higher level of exhaust cabin noise/drone. This system may not be street legal in all 50 states.
