MBRP's new 5" Quiet Tone muffler features a high flow 5" spiral louvered core, fits most 5" exhaust systems and is a direct replacement for all MBRP 5" performance mufflers.
With over triple the sound cancelling packing it eliminates drone under load or towing conditions and delivers up to a 10 Percent dB noise reduction compared to our regular performance muffler.
