Questions and Answers

Don't see your question? Ask us anything about this product.

  • In the muffler directional or can it go on either way. Notice a lot of drone on the highway at higher RPM

    Yes, the muffler is directional.

  • Just checking as an update, you won't ship exhausts to Michigan? I want to get your tune/tuner but I'd need the pipe too.

    We cannot ship exhausts to the US due to EPA restrictions.

  • Does the exhaust match the exact shape of the oem pipe? The tail pipe looks to be at more of a bend.

    No, it does not match the exact shape of the OEM pipe.

  • Does this fit the 141 inch wheelbase truck?

    This will fit.

  • Will it fit on a 2020? And if so what tuner should be used?

    These will fit on a 2020. We use this EFI Live Tuner for the ones that come through the shop.

Customer Reviews

Overall rating: 4.7 / 5 from 11 reviews.

Bought the stainless version to hopefully last a couple more harsh Alberta winters. Had to cut down the downpipe and second pipe to get things to line up, but that's just the game you play with aftermarket parts. With the muffler installed it doesn't drone on the highway but you can certainly hear the exhaust note around town and when you're using the whole sweep of the throttle pedal.

2016-2022 2.8L Duramax 3" Turboback Exhaust System w/ Muffler (FLO 875)

This exhaust system is A+ quality, it almost fits too well! After the nightmare that is removing my old exhaust was done this install was super easy. Had some questions but had I read the very specific instructions it would have done in no time! Highly recommend this and sounds great, lots of turbo noise!!
