Straightline Performance’s lightweight mufflers are designed for today’s noise conscious environments. The Lightweight muffler produces a low, deeper tone with keeping peak and mid-range volume similar to stock.
 
SAE J192, 1161 & SAE 2567 Certified Muffler!
With more noise conscious environments we have taken action to make sure we manufacture mufflers that provide a weight loss, maintain OEM performance, and meet or surpass sound restrictions.
All of this is achieved with no modifications to the original Lightweight ceramic muffler we have been selling for years now, no need to worry about upgrading to the newest latest muffler, as all previous manufactured mufflers are also compliant
 
Straightline will continue to update this list throughout the winter as we continue to Certify more Mufflers
