It sounded pretty good until I put shorty headers, trick flow heads and a cam in it and it just turned obnoxious. I kept reading how this Borla muffler was a little quieter while still having an aggressive sound when accelerating. The price was right so I pulled the trigger. This muffler is freakin awesome! The tone is fantastic and my neighbors love me again. For me it was all the good reviews come to life. Very happy with my purchase. ## Frequently Bought Together - BORLA 40348 ProXS ProXS Muffler 2.5" Center Inlet/ 2.5" Dual Outlet, 4" x 9.5" Oval, 19" Long Body, 25" Overall Length. Universal Part.
