S&S Cycle High Performance Slash-Cut Mufflers

• One of the most popular and cost effective performance upgrades you can make to a Harley-Davidson motorcycle is to replace the stock exhaust with a set of low restriction high performance muffler

• The stock exhaust pipes and S&S performance muffler makes a great high performance exhaust system with a low price tag

• The S&S Slip-On muffler will increase the performance of any stock engine

• This change alone will produce almost eight more horsepower and about five more foot pounds of torque on a stock 88 cubic inch Twin Cam engine

• Also highly recommended is the S&S performance mufflers for big inch engines because of the excellent low and midrange torque they provide

Important Product Notes

Note: Please see U.S. EPA and your respective state and local regulations to confirm noise and emission compliance.

Important Exhaust Notes:

• Note: With any new exhaust, we recommend changes to carburetor jetting or use of an aftermarket fuel injection control module.

• There is no warranty on exhaust pipes and mufflers with regard to any discoloration. Blueing is caused by tuning characteristics, cam timing, carburetor jetting, overheating, etc. and is not caused by defective manufacturing. No refunds on exhaust pipes once motorcycle is started unless there’s a manufacturer’s defect.

• Flanges and retaining rings are not included with most aftermarket exhaust for 1984-2013 Evolution and Twin Cam models. Re-use your existing hardware, or purchase replacement hardware.
