Rocket exhaust from diesel regen

I just picked up a '22 3500HD Denali Duramax. I've seen a couple reports of people saying they had their TT or FW scorched by the rocket exhaust from a regen on a diesel. Any truth to this? I sure as hell don't want to fry the skin on my FW if I don't have to. Banks claims their Monster Exhaust, with more of a side delivery, prevents this. Just looking for real-work experience if it's even something to worry about.

TIA,
Lyle

Not a problem for me. And I am in Phoenix. We just set a record for high temps. All of July days were 110 or higher

^You drug this thread out of the dumpster to suggest an exhaust cutout? Roflmao
First, the “rocket exhaust” lol ain’t gonna burn the trailer even if it’s a GM which has an almost north south exhaust tip. It’s especially not an issue with any Ford or Dodge because the exhaust exits in an easterly direction, to the side.

PS if you think it’s an issue, a simple turndown tip or a re worked tailpipe is far simpler and cheaper.

While some individuals have reported issues, the risk can be minimized with proper precautions. One solution you might explore is an electric exhaust cutout. This allows you to control exhaust flow, potentially reducing the intensity of exhaust directed towards your TT or FW during regen.

Banks claims their Monster Exhaust, with a side delivery design, can prevent exhaust-related issues. However, it's always wise to consider real-world experiences from fellow RV owners. Check forums or reach out to other Duramax owners to gather firsthand feedback and insights.

With careful driving practices and possibly an exhaust cutout or alternative exhaust system, you can likely enjoy your new truck and protect your TT or FW without worries. Safe travels!

I haven't done the exhaust on my 2012 simply because the only benefit I got on my 2003 ( - ) was my DW gripping about how loud the truck was now. Honestly never saw any measurable performance gain.


While any “performance exhaust” on an emissions intact light duty diesel is wholly a wasted of every cent and minute invested into it, your comparison also makes zero sense.
And likely not any gain on whatever “03” you had either unless it was making hundreds of hp more than stock.


My son changed his emissions downstream exhaust pipe to 5" on mis 15 RAM and it did give a deeper tone.

On a DPF equipped truck your DW probably wouldn't notice the difference in sound.


No difference in sound? FINE. Of course if there is no difference in performance everybody needs to pass a bunch cash out of pocket just to say they got it...

I've pulled two different trailers with my 2015.5 duramax probably totalling over 20K miles. never had any indication of regen temps affecting the trailer.

I did finally find a cover for the ugly pipe, seems like forever no one made a decent looking cover, but I just got a PPE SS slide on cover that is about 1/4" large ID than the exhaust, make a big positive difference in looks.

I'm considering it, for sure.

Aside from its quite likely NOT going to burn your trailer (have you even hooked the truck to it, or just armchair hand wringing?), unless you want the nice chrome exhaust tip and 89% less back pressure from the dpf back (extra lol at the Gale banks marketing team for that useless tidbit), save your $700ish + install.
Either A. Go see if it may be a real issue and/or B. Go to a muffler shop (if you can’t run a hack saw and a screwdriver) and have them either put a nice turndown tip on it, or have them weld in a little elbow and kick the megaphone thingy out a little to the side.
1 option is like 15min and under $100. The other is still probably only 25% the cost of a monster exhaust.

The piece of heavy equipment I drive at work says during regen to assure that the exhaust is not pointed at anything flammable. Trees, buildings, fences, cars, etc.

This makes me think they expect some serious heat to come out the pipe. The exhaust system is quite long also running down the chassis and up out the rear framework.

Sorry I missed that you're considering a Banks in your original post. The GM exhaust is directed more towards the rear and the Banks is directed towards the side. Other than that the installation process is something you need to consider, but it doesn't look like a tough job.
