    Great sound and quality for the $
    As my 16 year old said, "dad, it sounds like a freaking SRT" and I have to agree. The tips look great, it sounds amazing and there is virtually no drone. It is loud, and when you hit it, you'll hear it, but it's not obnixious, it just sounds deep and powerful.

    MRT cat back exhaust
    I just installed my MRT Cat back. It sounds amazing. Really let's the 6.4 breath! Install was about an hour, spent more time with fitment than anything else. It really looks so much better than the factory exhaust. Big shout out to MRT for shipping so fast. Super impressed with the quality of the pipes. Worth every cent! 2015 Black SRT -Ladson, SC
