Aeroturbine muffler 4"

Is anyone running this muffler? Does anyone have a comparison with another 4" straight muffler in regards to egt reduction?

Re: Aeroturbine muffler 4"

Just installed today with my new 4" MBRP exhaust... Love the sound and egt's are atleast 100 degreese below stock. Cant compare with a flow through muffler since I am not planning in installing the one that came with the system.. Contact Garrett at for the best prices and service on MBRP systems and Aeroturbine muffler.
