S&S® SPO® TOURING MUFFLERS
SPO Touring Mufflers redefine what ‘throaty big-block rumble’ means for a dresser. Mellow when you want them to be, but a deep growl when you get on the throttle. The perfect choice for long-distance riders, and for those who ride two-up. You can hear your radio and still get the enhanced midrange torque your bagger needs.
These mufflers have been re-styled and include a new sculpted alloy, high-temp coated black Xylan® end cap option with a machined-in S&S logo. All SPO mufflers are double-wall constructed to virtually eliminate bluing. Choose from show quality chrome or Jet-Hot® black ceramic coating finishes for the mufflers. Jet-Hot guarantees for life the black coating not to discolor, blister or peel.
Pick your SPO muffler finish, pick your end cap style, and rumble on down the highway.

This readout from our DynoJet® 250i chassis dynamometer shows why the S&S® SPO® mufflers are so well suited for touring motorcycles. The wide smooth torque curve is just the ticket for accelerating a heavy bike or pulling a trailer, and there’s enough top end horsepower to keep up with traffic anywhere.

It may be necessary to re-jet the carburetor or recalibrate the fuel injection system for best performance when a change is made in the exhaust system.
Dyno results are from tests performed at the S&S® Research and Development facility in Viola, Wisconsin.
