Easy install sounds great

Sounds great, only the muffler was dismantled and welded on from the Jeep Grand Cherokee 5.7 from 2008, the general procedure didn't rumble much, but enough everyone who heard it said that it sounds very good 😊

Pros
  • Absolutely amazing!
Cons
  • Without insurance

Sounds good! Best in Exhaust and Emissions

Used to replace the stock muffler on 2018 Sierra 2500HD 6.0. The sound is amazing! The drone is minimal, with a nice aggressive growl at the throttle. 100% build quality, fit and finish. I used a shortened model on my race car (Turbo 6.0) so I was dying to install it. I'm glad I rode full power for the second time

Pros
  • Good Thing
Cons
  • Blank

Good price! Excellent purchase!

Well I just bought this for my 2010 Chevy Silverado 2500hd 6.0. And it sounds amazing! It has a very deep idle and sounds amazing when pressed. I'll do youtube as I couldn't find any videos to see how it sounds at idle and when pressed. I will update this review when the video is done.

Pros
  • Complete kit
Cons
  • No instructions

Another winner. best part

The quality of these mufflers is second to none even though they cost twice as much. The sound quality is exactly what I was looking for. Deep sound when moving but not loud. If you're into it, it's flawless in what happens, but it's quite well muffled. After these two, another oval muffler with a large diameter exhaust pipe is used.

Pros
  • works great for me
Cons
  • very expensive

Excellent quality and great sound!

I was looking for a system for my wife's new rmax and only know of two models on the market, one very loud for 300 pieces and the other not much louder than the standard model for 750 ! So I added them along with a mini resonator and that's the perfect sound. So much so that I've pulled the system out of my Pioneer1000 and am building a system for it!

Pros
  • Hands-free operation
Cons
  • There are disadvantages

Great noise reduction for what it is

I have a Miata four cylinder turbocharged vane exhaust that was just ridiculously loud. I needed something to push at the end of the race and this thing worked wonders! I really like that it has a 4" ID on the ends so it can slide over a 4" exhaust and then the resonator section is reduced to a 4" OD. Same size as my exhaust pipe. The flow is not interrupted and the noise is noticeably muffled. I'll check the db reduction at work tomorrow. Unbeatable, especially for the price

Pros
  • Decent performance
Cons
  • Miscellaneous Miscellaneous
