Sorry guys. That Flowmaster exhaust system kind of disappointed me. I guess no matter what you do to 4 cyl exhaust system it sounds like a Honda Civic. I even put on a 2.5" 40 series 2 chamber muffler and it sounds like rice. The 3 1/2" exhaust tip doesn't help matters either. I know I'll never hear the end of this, but you live you learn.
