Cleaning out my garage after I traded the JL for a JT. Dynomax 39537 muffler delete pipe for the 3.6l JL with an extra rubber hangar (which is most of the install work ). $75 I pay shipping.
I mean.... ask almost people & they’ll tell you mufflers don’t really get you anything, but it’s loud and fun to drive. Anything I felt was more likely the cause of hitting the gas and making the engine roar. I definitely liked the sound!!
