Undercover Performance Muffler

For those looking for the ultimate retro exhaust, the British Customs Sleeper Pros are the answer. The Sleeper Pros feature the true vintage look and sound that gave the original Sleepers their notoriety, but include a number of improvements. Styled to look the part but packing the punch of a free-flowing, fire-breathing exhaust system. The authentic retro sound back and better than ever with the new Sleeper Pro design, too. Best of all, these slip-ons are quick and easy to install.
