LML DURAMAX 5" Flo Pro Exhaust Review

[@user-ki8nw5ki5o]

I’m so torn between buying a 6.7 Cummins or a 2014+ LML/L5P. The Cummins is a beast, but the whistle of the Duramax just gets me

[@ColinMcEvoy]

I actually just picked up a 2015 cummins mega cab. Loving it so far but I do miss my 16 duramax. I'm excited to see how well the cummins treats me. I will have a video about it on the channel in the next few weeks!

[@user-ki8nw5ki5o]

@@ColinMcEvoy can’t wait for it! I just wish the 6.7’s had a louder turbo spool like the DMax’s do

[@ColinMcEvoy]

@@user-ki8nw5ki5o Intake and an exhaust should fix that i think haha

[@Foxracing2320]

Well you’ve helped me decide on which exhaust to buy :) what wheel and tire size are you running? Love the truck!

[@mrcontroversy222]

Did you find a flo pro? Are you in the us?

[@countrycaretakerpropertyse7981]

I live in Canada. We can get it up here.

[@Collectingwithrandd]

Love this truck ! Hopefully picking up a duramax soon! Sounds beautiful man

[@ColinMcEvoy]

You definitely should!! I loved my duramax

[@mrcontroversy222]

Ever get one rand? I just got a super clean 2015 Denali duramax. I Effin love this truck. I need to find someone that will sell me flo pro in Texas....😢😢

[@gidget8010]

Sound good I guess. Ok so I am from Montana and my dad and I had to take our 2002 gmc Duramax apart cause the head gas-get was shot and we were going through like a gallon of coolant a month so ya took it apart and then put a new Exhaust cause it was rusted and then took the muffler off so now it is straight pipe and then got a chip for it also and now it runs like a champ. Exhaust is tractor 7-10??? um one question though for you is what do you think would make it run at the top of it game???

[@RyanMurraythereal]

i appreciate this review. Im going from a straight pipe shortbed LBZ and im tired of hearing the old lady complain about exhaust. And towing it drones bad. The LML im picking up is all stocks so I've been thinking this kit with deletes to make a good sounding quiet truck

[@ColinMcEvoy]

yea you'll love the system with a muffler, its still loud when you want it to be and quiet while cruising with no drone

[@ozzynomicon2817]

I love my 11 duramax but i hate the rolling wet fart sound our exhausts make. I miss my old crisp lope of my cammed 5.3 with duals. Anyway i can dual it and get the sound on ththe lml 3500

[@betaakey]

Nice colored truck! More beautiful than my white Chevy Silverado 2500HD long bed work truck

[@ColinMcEvoy]

hey white truck lives matter!

[@pimpinchevy75]

What tune are you using? I want to delete my truck. I need it to stay reliable because I tow a lot! It’s a 16 duramax

[@ColinMcEvoy]

What tune do you have?

[@DuramaxDsl]

Which Flo Pro Muffler is this? The Twister or ?

[@thenamesjay69]

Was this with the delete? The def delete?

[@rogerbackyardfkitallup1164]

im hard hearing if u said it I didn't catch it, is this the Cat back ? or the down pipe back ? ss660 or ss664 downpipe im pulling a whopping 9mpg with my 13 sierra RMT package, pulling a trailer ( kinda missing my 01 now)

[@ColinMcEvoy]

hey roger, no worries! This is the downpipe back exhaust. you may want to check if you have a v band style clamp at the downpipe or 3 bolt style. they changed it (in 2015) but you might check just to make sure. SS664 SHOULD be the kit you need (comes with a muffler) or SS664NM for the kit without the muffler (sounds better with muffler for drone at highway speeds) but i'd advise emailing flo pro directing just to be sure.

[@robertbui6640]

Hey Colin, great vid and sounds amazing. I know you posted this awhile ago, but had a question for ya. I've always been a Toyota truck person/ gas truck person. Although I'm considering a diesel for the future and open to all brands. I've test driven a 2014 ram 2500 cummins and a duramax 2500 2015 before, but I don't know much about diesels. What are your thoughts on the duramax/allison and has it given you any problems? Thanks and again great vid! :)

[@ColinMcEvoy]

To be perfectly honest youll be happy with either one. I was a service advisor for 3 years both for chrysler and chevy at one point. Both cummins and duramax have their quirks and both are very strong reliable trucks, the cummins is easier to work on for sure. If I didnt buy the duramax I would have gone with the cummins because it is a good truck, I ended up choosing the duramax because of the interior features as well as ride comfort from the chassis. I get comments ALOT about how well the truck rides from people without even asking. No one really expects a big lifted truck to ride so well but that was why I chose it overall. I love both brands though, it will really come down to your preference on whether or not you tow or you daily drive it or want to lift it and take it to shows or make a race truck. Either way, you cant go wrong!

[@ryanaldrich7474]

Are you saying you bought the one that came with a muffler or did you install a different one?

[@ColinMcEvoy]

bought the one that came with a muffler

[@YZracer110]

Hi I was wondering if you could send me the actual 5 inch flo pro exhaust you got bc I haven’t been able to find the right one I need for my 2016 Chevy duramax. Thanks

[@ColinMcEvoy]

[@trevorlouque7541]

Is that just the exhaust system or a delete too?

[@humbertoloera104]

Curious too

[@jonathanpatron7970]

I like the sound good job What is the Exaust part number

[@ColinMcEvoy]

I would say just go to Flo Pro’s website and find it through your specific make and model, there’s a difference in some of them so I don’t want to give you the wrong part number 👍🏼

[@jonathanpatron7970]

Got it thx

[@zigzach361]

I’m assuming you have def and egr delete? Also any fitment issues with the 37s on 20x12?

[@ColinMcEvoy]

Yep all Deletes, and it rubs slightly in the front but not bad!

Where did you purchase the exhaust with muffler set up?

[@ColinMcEvoy]

[@derekortiz3663]

Do more vids. You're better to watch than that dirtymax Jack tool.

im not sure what you're trying to say shawn haha

[@shawnridgeway1509]

Colin McEvoy you were saying there is no drone with your exhaust set up and your roommates is similar to yours. Is there a lot of drone without the muffler?

It is deleted with tunes and intake. That was it though

[@1duramaxhd]

Guys dont do the muffler. Strait all the way through.

[@ColinMcEvoy]

the muffler is straight through itself, theres no blockage at all. it basically only helped with drone

[@ScottFlorindo]

im sure it sounds great but its tooo quiet for me lol

[@ColinMcEvoy]

I had the muffler on it, you could see straight through the muffler so it wasnt that big of a difference at idle and revving. The biggest difference was the drone at highway speed, my friend had an identical truck but without the muffler and his was def louder.

[@SS14PSI]

All I heard was 6 minutes of talking
