    DPF and CAT delete

    It was very easy and had no issues with any part except for the exhaust. On our cab and chassis this exhaust didn't fit up to the existing muffler and tailpipe so we had to fabricate the tail end of our exhaust system. Overall a very good kit.

    2 piece 4" pipes with muffler, Cut stock tailpipe 1/2" longer, Fit perfect!
    Bolts marked 88 not 8.8 Stretched and parted at threads-blocker.
    Graded studs for exhaust would have been Nice, GDP kit.
    EZ-LYNK No Problem.
    Thanks, don

    Exhaust system.

    If I had to complain about anything it would be that instructions while a little vague on where to cut it.
    But if you mark it up and pay attention to what you're doing everything falls right into place.
    The system fits terrific like it was made for the truck from the factory so I would have to say it's a very good product. Also sounds great with the muffler not much different than the factory exhaust and that's what I wanted a quiet truck not a lot of noise.

    Great quality and sounds amazing

    Makes your diesel sound like a true diesel! Great fit and finish. I installed the exhaust with the muffler and love the way it sounds. Fast shipping and great customer service!

    Great customer service

    I had a few questions on my order, I also had a few technical questions.
    They replied both by phone call, and on line to me.
    It's true when they say they are dedicated for customer support.
    I am very happy with my purchase.

    Excellent fit

    All the advice you can get about taking your time and being patient, is spot on. Loaded the tune, disconnected all sensors, started at the front and removed all components, did have to cut the double wall cat / Dow pipe to get the cat out, (to avoid dropping TM cross member), don't cut your over axle pipe to DPF filter until you measure it up, start at front and tighten nothing until it's all aligned. Easy, highly recommend getting a new tip to replace the stock Duramax cooler / tip, just sounds weird and constricts the departing airflow.

    show me exhaust muffler will fit my 2015 3500 8-ft bed truck four-door

    thedieseldudes

    Yes, it's universal fit for all pick up models, only the short bed/single cab configurations need minor cutting for perfect fitment

    Is this a 5"? If not do yall have the link for a 5"?

    thedieseldudes

    This is 4". I will have a team member reach out to you for the 5" pipes as those are full exhaust systems and a bit different from the cat & dpf delete pipe
