Installing 5" Exhaust and Tune on GMC Duramax 2500 | Insane Turbo Whistle

[@wayawolf1967]

I ran the 5 inch for about 6 months but changed back to the 4 inch. Towing 10,000 lbs cross country the 5 inch had too much drone. Couldnt hear the radio or have a conversation with passengers without yelling. The 4 inch with a straight through muffler sounds great with an oversize turbo.

[@coyote208]

That’s what I was wondering.. I have an untuned diesel but was never a fan of the overly obnoxious sound on a straight piped untuned diesel.. especially a ford lol. Ridiculously loud. So you did a 4” and a straight muffler? What’s a straight muffler

[@douglashughes1392]

I straight piped my 2015 duramax at 12k miles on the odometer and never looked back. Love these trucks

[@SwampBoysGarage]

Love them and they sound so much better straight piped.

[@douglashughes1392]

@@kelvinmartinez5332 it’s a flo pro 5”. Many websites sell them although I’ve heard they are much harder to find now.

[@Reillycrown]

Does the truck need to be deleted before I can straight pipe it from down pipe back? 2015 lml, will it throw any codes

[@douglashughes1392]

@@Reillycrown you have to tune the ecm before you can straight pipe. You will have more power, better fuel mileage by far, and a more reliable truck. Need a lift pump for highest horsepower tunes though

[@DachsAutos]

That sure sounds happy now with that upgrade! That craftsman creeper is a classic! I've had one in my garage for years. One of the first things I got I think after the tool set from my late grandfather. You need a matching trailer now for your runs to Copart! You'll be sure in a few years when Tyler makes or misses his curfew on a Friday night!

[@SwampBoysGarage]

I’ve had that creeper before Tyler was born. Lol. Definitely need a trailer and upgrade from the U-Haul. Lol.

[@CoolGuyCody]

Love it! I’m running a similar setup. 5” straight pipe, tuned, 6.6l resonator delete (billet capped, 1 1/2” rubber pipe plug from Home Depot works ok too), 8” axel dump tip. I’ll post a few video soon.

[@SwampBoysGarage]

Awesome. Thanks

[@cameronwatson1522]

To get this straight, you only are tuning, straight pipe delete, and disconnecting the EGR. This will make it so the truck doesn't rely on DEF?

[@dodgecummins0530]

Also an exhaust tip 7+” gives it even more of a deeper tone and if you want it even louder than that look up “axle dump exhausts” it’s where people cut the exhaust after it goes over the rear axle so the sound bounces off the ground but personally that’s a little to loud for me 😂

[@SwampBoysGarage]

Thanks. I’ll look into that.

[@ChazzleDazzleVideos]

I hated putting the 5# on my lbz but I loved the sound and mileage+power I also did the downpipe at the same time and run a 150 tune plus plenty of supporting mods for fuel air and trans. If you ever have to remove those rubber hangers just spray them with wd40 or penetrating lubricant and they slide right off.

[@davidstigant4713]

mine seems to get worse mileage on my tune 5

[@ChazzleDazzleVideos]

@@davidstigant4713 mine is normally around 23 in that tune but with all the power I don't have to press the accelerator more than quarter throttle and still pulling faster. There a couple of clients about 30 miles from my place and when I go out to do work on the cabins or whatnot I usually get in the 25s for mileage because it's a 60 mph zone the whole way and a straight shot with little hills so somehow I get around 2.5mpg less driving 70 over 65.

[@IBEWFour90]

I have the same exact truck just did the same exhaust also. I'd recommend doing at lift pump I did an air dog 4g2 165 before the exhaust I felt a difference right away no dead pedal feel and alot more responsive. Will also help the CP4.

You can do a street legal tune. You don’t have to do an off road tune that requires you to remove the catalytic converters and def system. I’m not sure what all they inspect there but to answer the egr question, you can do an off road tune and leave the egr in place. You just put blocker plates in front of it.

Does the rune void the factory warranty

[@SwampBoysGarage]

Yes

[@jimharrow8104]

Nice...

[@SwampBoysGarage]

Thank you

[@Philipbanks7]

Will this work on a 22 L5P?

[@SwampBoysGarage]

It’s a different process but the place I bought my tune has the stuff to do the L5P

[@MrDbro94]

Around how long did swapping the exhaust take you?

[@SwampBoysGarage]

Just the exhaust was a couple hours. Maybe 3 hours.

[@nlh719]

Never worked on newer Duramax's but done lots of transmissions on LBZ's. One thing I always hated about Chevy's was the exhaust placement. The kit you bought is it assembled with clamps or did you have to weld it?

[@SwampBoysGarage]

It was all with clamps. No welding.

[@Alex-ws4ll]

Did you get rid of the dpf?

[@bentonstaffel2471]

Theres no way you cant tell.

[@Alex-ws4ll]

Hints the reason of the question

[@SwampBoysGarage]

Yes I did.

[@curranjohnson12]

What kit is that? I’m looking to do the same thing.

[@SwampBoysGarage]

MBRP

[@trevdawg6.6]

Did u just unplug the egr then?

[@SwampBoysGarage]

No I put blocker plates a couple weeks later

[@cesarcortez2820]

Will it pass smog with that?

[@SwampBoysGarage]

No but not an issue where I live.

[@odindiaz3151]

Holdup is this truck deleted or was that just an exhaust?

[@SwampBoysGarage]

Off road tune and exhaust
