For those looking for the ultimate retro exhaust, the British Customs Sleeper Pros are the answer. First and foremost, the Sleeper Pros have a deep rumble with a rich tone inspired by the distinctive sound the vintage Triumphs of the 60s were notorious for. The Sleeper Pros have a revolutionary one-piece 304 stainless steel body that improves their durability and eliminates the need for ugly seams that usually come on hand-welded exhaust systems. To improve their performance, the Sleeper Pros have innovative HVO™ technology that emphasizes uninterrupted airflow to increase horsepower. The Sleeper Pros also include a rubber mounting system that isolates engine vibration from the frame and eliminates bracket fatigue, extending the longevity of your investment. Best of all, these slip-ons are quick and easy to install on Triumph Bonneville T100 with VIN less than 437492.
