Its OK. No sound difference!

"Don't buy this for sound! There is no sound difference between stock. I just installed mine 3 days ago and I feel a very slight increase in power but not much! Great to buy if you have to replace your exhaust as a stock replace option. Quality is good but sound is very disappointing."

3. 0 duramax

"I really want this exhaust due to it being the only one that uses the stock exhaust holes in rear bumper. I would love to hear how it sound before I drop 1300 bucks. Is there a sound clip or video anywhere for this on a 3. 0 duramax"

Chad (5/5)

Do not buy the Vulcan

"Have it installed on my 3. 0 diesel at4, it literally sounds like a whale is doing a mating call every time I tap the pedal…it’s so embarrassing driving with this exhaust sound on my expensive truck, worst Purchase I think I made, even worse design for just a. Terrible sound"

Marco (1/5)

"I have not received it yet ordered it two months ago said it was in AFe never shipped it to me still waiting not sure if I’m ever going to get it thank you"

Q&A

Is there any reason this kit wouldn't work with a '23 LZ0?
Those have recently been confirmed to fit the 2023 models.
I have a 2022 Sierra. The exhaust has a single pipe existing on passenger side behind rear tire. It does not have the dual cut out in rear bumper. Will this kit work? If so, any additional items needed for installer?
Hello, You would definitely need to have a bumper with the cutouts. Would not need anything else for install besides the tools. And some penetrating lube to start spraying down the bolts. -Sands
I cannot find ANYONE online with this set up for a 3.0 Duramax. I would love to see some videos on the sound. Do you have any you can put on the website or a YouTube channel?
Hello, Unfortunately with todays, DPF and DEF equipped vehicles. The emissions is what kills 99 percent of the sound. Anything you do behind them is basically for cosmetics. There are small benefits. But you are not going to get any noticeably better sound unfortunately. -Sands
Does this improve performance and/or sound compared to stock exhaust for the 3.0l duramax Diesel engine?
Unfortunately very little. All of your restrictions are going to be ahead of that section that you are changing. It is going to be mostly for looks. -Sands
