I got a full H pipe system with headers. These aren't for everybody they are loud and have a bunch of drone humming and cabin noise in the car at street cruising but clean up and sound awesome at freeway speeds ### ⭐⭐⭐⭐⭐ Se escucha excelente *by on Reviewed in Mexico 8 September 2020* Suena muy bien en el coche, excelente producto. ### ⭐⭐⭐⭐⭐ Super 10 greatness *by on Reviewed in Canada 5 August 2025* Great muffler. Put on my 2003 mustang GT with everything else stock. as loud as it can be without getting pulled over and does have a pop or two when pushed hard.
