My old truck was an 05 2500. It has had a 5 inch straight pipe on it ever since July 4th weekend of 2006. I never thought the truck was loud. I only thought it was loud when I had the windows down, you definitely could hear that truck from a mile away. I love 5 inch Turbo back straight pipes on 6 Cylinder diesel engines, sound great on cats and Cummins. With the windows up, I could have the radio on and not even be turned up a lot and still here it just fine. Hell, the damn hvac fan was louder than the exhaust was. Lol

[@mikesevilla8692]

Can’t wait to see more of this truck man. Great vid as usual

[@JM-tc2ou]

I did a 4” TBE axle dump…for about a week. 🤨 It drove me insane while commuting. I added a straight, flow through muffler and that removed the drone just enough, without killing that great 5.9 sound. Happy medium.

[@V1NCH1INZ0]

I was so close to doing the 5" straight pipe and man, I'm glad I didn't. I daily my truck so I put in an aerotubine resonator, cut the tailpipe off, added a tip, and left the cat. It made it more aggressive, but didn't become overbearing. Another thing that I'm glad you mentioned was the clamps. That's something you don't really think of at first. You cannot really beat the stock hanger setup

[@JustDiesels]

Yeah your setup is spot on for a daily! Even on the cheaper exhausts I always order my own lap joint clamps. So much better than u bolt style ones!

[@anthonyv9699]

Awesome video! I had a 5” straight pipe like this on my 2005 Ram 2500, and I know what you mean about the mirrors shaking 😂 I did notice a big difference between an axle dump and the stock exit location. Without all of the resonance under the truck, it made it more bearable. I also noticed a difference in exhaust tip size changes the drone as well. A 6” tip was somewhat bearable, but a 7” tip made it drone much more.

[@JustDiesels]

Yeah an axle dump is always louder in the cab for sure! I prefer the clean look though!

Andrew, I researched the options for my 03 3500 way back when and upgraded to the 04.5 4" upgrade with the 4" turbo downpipe along with a very nice and quiet muffler (your wife will be so impressed), which is the Donaldson #M090544. Quiet, straight through design, CFM far exceeding the factory 350cfm and eliminating any "droning". I give it 5 ⭐

Just got this same kit delivered, sounds good, I have to fab up down pipe as I did second Gen swap. Looks like I didn't have to order another piece of pipe since the quad cab short beds will not need that extra piece. Sweet

[@skinnypete22]

I have a ‘15 ram 2500 that I had put 5” on and went with the axle dump and 8” tip and it was cool for a while but it was loud and had a ton of drone. I changed it to behind the rear wheel and 6” tip and it’s loud but not obnoxiously loud and I like that

[@idahobuckaroo8348]

Straight pipe exhaust is best. All my Dodge Cummins trucks are straight piped; however, I never run an axle dump. I take the exhaust to the edge of the truck body line; it helps reduce the sound in the cab. Compound turbos using turbo blankets also helps reduce the exhaust roar while keeping EGT’s down, faster spooling, and increasing RWHP.

[@ericl5973]

I like the look of the axle dump but it adds drone in the cab. When I bought my truck, it had a stack which was really loud. Running a 4in axel dump now but I want to add some mufflers to quiet the truck down for the long road trips.

[@jonathanoakes2734]

Perfect intro😂

[@speedshift1016]

Add sound deadening and thermal insulation. It will help with the noise as well as it will help keep the interior of the cab cooler and or hotter

[@jeffreyyeater1780]

I have a quad cab with 8 ' bed . I run the MBRP straight exhaust . Its really not that bad at all. The only time the drone bothers me is when I towing at a certain RPM. At highway speeds it not a problem at all. It is a very long exhaust system .maybe thats helps too.

[@markp4967]

[@brandonm6052]

Back in the day I threw a Flo Pro resonator I believe it was on my 05 straight pipe, It tamed it down...almost too much. My dad's 07 5.9 has a Magnaflow stainless 5" with muffler and if a guy doesn't want a straight pipe it's about perfect.

[@FL_BOY392]

Sounds good 👍

[@steves9955]

Holy sh*t that thing is clean underneath

[@MrFlip001]

So, Magnaflow actually used my truck to prototype their 5” exhaust. Excellent fit and love the stainless. Flow through muffler as usual with Magnaflow. However, there was a noticeable drop of low end power with the larger pipe and cat delete. Drones for days as well. Ended up taking the delete pipe, cutting it in half, cutting the tapered ends of the cat back to where they are 5” and welding it all together to get a 5” cat to bolt back in. Got my bottom end back and sounds much better.

[@jeffreyyeater1780]

I just put my muffler back on after running a straight pipe for 2 years . I swear its got more low end w / muffler. No cat . Just muffler.

I have a 2004 5.9, had it straight piped but didn't like the sound. Did some investigating and found the exhaust manifold is not fed evenly from the engine. It's 4 cylinders vs 2 cylinders, (sounds like a 4 cylinder car to me). So I put a 2nd gen manifold, which relocated the turbo and now is fed evenly and it sounds great, just like the older cummins.

[@codyd.4711]

[@_astralxinfluenced_2799]

Just installed my 5" NRE Perf. turbo-back exhaust today, took me a little over 2 hrs cause I had to chop it in more than 1 spot; figured that out after struggle-bussing for far too long. Few differences from the kit shown in the vid vs. mine (granted it's a 2 yr old kit vs. current). All the exhaust hangers on mine were adjustable u-bolt style, except for the side exit piece - which the hanger is welded to the pipe - but I did an axle-dump as well so that wasn't used. Only 1 of the 4 u-bolt hangers actually fit my truck (05 Ram 2500) - the 1 that has 2 hangers on 1 clamp - the rest of them didn't fit, & even the 1 that did "fit", the 2 hangers were too long, so I had to flip the isolators 180° & it now looks like the exhaust is holding up the truck, if that makes sense. Lol Also, take some Scotchbrite to the cast elbow off the turbo, it'll make install way easier. I cut my OE exhaust right where it was cut in the vid, but had to make another cut on the downpipe cause there was no amount of finagling that was getting it past my 48RE (also had to loosen the bolt that holds the trans dipstick in place, gently bend it over, & re-tighten the bolt, otherwise the 5" downpipe would make contact with it). Kit also came with an exhaust tip, that wasn't mentioned, so that's nice.

[@orBMW]

I love the wheels and tires. What make/model wheels are they?

[@richardturner7560]

Just FYI axle dumps drone more in the cab then if you just left the corner exit on. I run a 5” straight on my 4th Gen with a manifold swap and I love it. Not overly loud but my truck is a crew cab long bed with a corner exit.

[@Richie_RHD]

I did this on mine a long time back. I ended up putting the tail section back on over the axle dump and it made the in cab super super quiet. My neighbors however still complain

[@thim8009]

I forgot what my 05sounded like stock. It's been a straight pipe from turbo back for over 15 years.

[@vooduuchild3601]

On my long bed, I did a side exit at the end of the bed, diagonally and not having it pointed at the pavement makes it much quieter inside the cab. 03, 6 speed 4x4, 4 door long bed. I'm betting with a diagonal side exit at the tail, your cab noise would go down. I know you have reasons for being axle dumped, probably clearance offroad, but I thought I'd share my experience with my 5 inch. I also have S&B intake, tuner and all the goodies.

[@tommydmot7725]

I did a 4" from the downpipe back on my LML Duramax it's loud outside especially when you lay on the pedal. But on the inside you feel it more than hear it. 5" is overkill

[@thesickening0169]

A couple things, for anyone who happens to read: I put a MBRP turbo back exhaust on my 2004 2500 Cummins a couple years back. The entire system was shipped in a large box. Thats it, just a large box. No foam, no bubble wrap, nothing. The pipes were smashing around during shipped. The box looked damaged, and few of the hangars were sticking out of the box too. Opened it up, found two of the pipes dented from smashing into eachother. Anyone who has looked up exhaust systems for these trucks know that MBRP is not inexpensive whatsoever. This was unacceptable regardless of price, but even more so considering the cost of an MBRP exhaust. Reached out to MBRP, and they did make it right (after jumping through quiet a few hoops). They had said something like some of the manufacturing had gotten moved elsewhere since being bought out or something. Something else to note that has annoyed me, is that I payed for a 5" turbo back exhaust. Yet, the downpipe from the turbo is actually 4" then flares out to 5" at the mid pipe. Nowhere in the description did it state that it was 4" flaring out to 5". A buddy of mine bought a 5" from Dynomax or something, can't remember. He paid about half the price I did, and its a TRUE 5" exhaust. Sounds great too. That all aside, as far as tone and volume, I started with MBRPs muffler. The truck sounded good, but a little too tame for my taste. Ordered the straight pipe, swapped it out with the muffler, and love the way the truck sounds now. In the video he stated that straight piped, the truck is too loud for towing or long hauls, I disagree. I primarily use my truck for those exact reasons, either towing or long road trips, and I think it sounds great. Yes its loud, but not obnoxious. I get no droning either. Just wanted to throw this out there.

[@JustDiesels]

Just to add to this, I've ordered a TON of exhaust from different brands over the years. I've never gotten one from any brand that wasn't just tubes thrown in a box. It kinda sucks. Some have some slight cardboard padding, but not enough so I've just gotten good at fixing dented pipes haha. As for the drone, a lot of that depends on the exact truck, wheelbase etc, but mine was WAY too loud to daily drive for my taste as a 5" straight pipe.

[@thesickening0169]

@@JustDiesels Gotcha. That is disheartening to hear about all the pipes just being thrown in a box, lol. I will hand it to MBRP though, they did take care of it. Oddly enough, as you mentioned in the video, the exhaust hangars didn't line up very well in the MBRP system either. Anyhoo, keep up the videos, please! They are excellent, informative, entertaining, and very well shot. 👍🏼
