Reviews

  • Is this 4-5" inlet? I have an ecodiesel and I dont believe the o.d of the pipe is 4". I am pretty certain it a 2" but if the inlet size isn't 4" will this work for an ecodiesel and if not do you have another product that doesnt require buying a whole exhaust system?

    This will not work unless you have a 4” exhaust.

  • Are these straight pipes meant to be welded or clamped on? Thanks

    Dan Sjolund | 3/11/2024

    Clamp - on

  • I have an mbrp 5” inch exhaust and it has a high flow muffler. Can I take the high flow muffler out and clamp this straight in or do I have to weld it.

    Brandon Harmon | 5/13/2022

    Yes, clamps will work fine.
