Performance and Application

By removing both the catalytic converter and DPF filter, this system enhances exhaust flow significantly. As a result, you will notice improved fuel efficiency and greater engine power. The larger 4" or 5" stainless steel piping ensures better airflow, reducing exhaust gas temperatures. Moreover, the straight-through design helps maximize flow, making it perfect for off-road and competition use.

This race exhaust system offers several advantages, especially for Duramax owners looking to boost performance:

  • Durable stainless steel piping to withstand harsh conditions
  • Available in 4" or 5" diameters to match different performance requirements
  • OE-style hangers provide an easy, secure installation
  • Straight-through design maximizes exhaust flow, helping the engine perform efficiently
  • No bungs, making this system ideal for off-road applications and competitions

Installation Considerations

This product is intended for off-road use only and requires race tuning to operate correctly and achieve optimal performance. The kit includes all required hardware and clamps for installation. Do-it-yourself installation is possible; however, professional installation and tuning are recommended to ensure proper fitment and correct operation. Depending on your vehicle’s configuration, minor modifications may be required.

Love it.
Color: Rainy-Rainbow
This glitter is gorgeous on. Really easy to apply, sprays evenly and a good amount at once. It wasn’t a nightmare to deal with either clinging to things it fell/rubbed onto which I was pleasantly surprised by. It cleans up very well. A little goes a long way too, so it should last a while. It stayed on my body fairly well throughout the night too. I have really sensitive skin so I was hesitant to even get glitter at all. I tried body glitter 2 years ago but it was a liquid spray kind and I broke out in an intense rash all over. I also have a chronic hive condition so my skin flares up from products due to sensitivity. I did not have ANY issues with this glitter.

Absolutely Stunning Glitter with Thoughtful Packaging! | Rainy Rainbow
Color: Rainy-Rainbow, Color: Rainy-Rainbow
This glitter is breathtaking! The sparkles catch the light very beautifully — it has a mesmerizing, holographic shine that’s perfect for adding extra pizzazz to any project. When it arrived, I was pleasantly surprised at how well it was packaged. The box was securely sealed, and everything inside was perfectly intact—minor spills, no mess. A heads up on opening the entire thing: the round container’s Lid is screwed on VERY LOOSELY. Be mindful when you’re unboxing. Screw it back on very tightly. The spray nozzle on this bottle gives such a beautiful, antique perfume vibe—it really elevates the whole experience. It sprays the glitter perfectly, so it’s easy to get a flawless application every time. (Don’t forget to keep the little nozzle cover to protect it!) Honestly, I wouldn’t apply it any other way than with the bottle—it just makes everything so much smoother. 🤷🏻‍♀️ If you happen to go overboard, just grab the closest shirt and wipe off any excess. No point in wasting any of this stuff! :) Oh, & those two little gloss bottles are actually glue, which is perfect for keeping everything right where you need it to be. Here’s a little pro tip: I used the same tape that kept the box sealed to reseal the lid of the round glitter container until I’m ready to use it. Worked like a charm! 😎 It’s a small detail, but it will keep everything neat, and prevent unwanted glitter explosions in the future. If you’re a sparkle lover, you’ll adore this glitter—it’s as pretty in person as it looks online!

Good product
Color: Purple, Size: 3.72 fl oz
Very good. Gave off a good purple shimmer but not too chunky. Definitely would our have again. Got for a Halloween trick or treat to go with my Ariel costume and it was perfect. Not sticky or anything. Sprays just like a perfume and dries quickly. Does transfer but still a very good product. Not a strong smell either. Definitely worth the amount of money. Does wash off very easily as well.
