        Is there a U-tube vid covering the sound of this unit? It sounds good to me on the GT vid but the ecoboost sound icon rates this in the red. I want something in the green, louder than stock but not very noticeable while running at speed. Thanks.

        • The SLP Loudmouth LM-2 Axle-Back Exhaust currently does not have an exhaust video, but we are working on having a video for all our products. Keep checking back to our site!
