Upgrading your exhaust in your LBZ Duramax 6.6L is possibly the most popular upgrades a diesel enthusiest will do. Upgrading exhaust not only aids in power, fuel economy, and overall sound, but it also looks really cool. This 5" Aluminized Steel Cat Back kit from Diamond Eye is an excellent upgrade for your LBZ Duramax. This kit also includes an upgraded turbo direct pipe that features CNC machined end-forms for precise fit, mandrel bent tubing for smoother flow from the turbo and is covered with special thermal resistant wrapping to help reduce your EGTs by up to 150 degrees.

DETAILS OF EACH MUFFLER/ELIMINATOR PIPE OPTION

Diamond Eye Muffler: This is the standard muffler that comes in the kits. Featuring a stainless steel construction and perforated core, you really can't go wrong with this muffler. The muffler itself gives the truck a deep tone, while not being overly loud and does a good job of reducing exhaust drone.

No Muffler / Straight Pipe: For those that want the uninhibited sound of straight pipe, here it is. This is a complete kit, but instead of shipping with a muffler, you will receive an eliminator pipe to give you the exhaust bark you're after. If you ever want to put a muffler back into the system, you'll merely need to remove the eliminator pipe and install a proper length muffler.

EXHAUST TIP OPTION

No, it won't add 20 horsepower or give you better mileage, but adding an exhaust tip simply adds the finishing touch. As another way to make ordering easier, we allow you to simply add Diamond Eye's most popular tips right from this page to complete your kit. You have the option of Diamond Eye's 5" to 6" angle cut, rolled edge, bolt-on tips in either a stainless steel or black powdercoat finish. And if you either don't want to add a tip, or would like to choose a different option, no problem, just select "No Tip(s)."

Great spring or summer fit
This came a little bigger than anticipated, but other than that, this is a great quality set. It's a little lighter, which is great for spring or summer. The color is just as pictured and I'm impressed with the altogether fit.

Excellent 5-Piece Suit for Graduation; Great Fit & Generous Pant Length
Color: Navy, Size: 16, Color: Navy, Size: 16
Sizing Profile & Custom Hemming: I took a bit of a gamble ordering this, as my son is just transitioning out of a size 16 and into a size 18. I ordered the 18, and everything fit him absolutely perfectly! A great detail for parents to be aware of is that the pants run generously long. This is fantastic if you have a taller child, and because it is a proper suit, it gives you the extra fabric needed to hem the bottoms for that exact, custom-tailored fit. The Tie Options (Hardware Details): This 5-piece set comes with both a bowtie and a standard faux necktie. The hardware on these is distinctly different, which is a helpful detail for buyers: the bowtie is a true clip-on style, while the standard necktie utilizes an elastic/rubber band that stretches around the shirt collar (it is not a clip-on). Both options look incredibly sharp and work very well depending on the look you want. Comfort & Breathability: My son wore this entire outfit for his graduation ceremony, and the material performed beautifully. Despite wearing a full suit, he did not overheat at all. The fabric breathes surprisingly well for formal wear, keeping him completely comfortable. Final Verdict: Overall, this is a wonderful outfit with absolutely zero complaints from either of us. It fits great, offers versatile neckwear options, and is comfortable enough for long, formal events. 5 out of 5 stars! Pros: • Perfect Transition Fit: The size 18 fits exactly as expected for a growing teen. • Generous Pant Length: Provides plenty of extra fabric to properly hem for taller kids. • Breathable Fabric: Kept my son cool and comfortable throughout his entire graduation ceremony. • Versatile Accessories: Includes both a clip-on bowtie and an elastic-band necktie. Cons: • None; it is a fantastic, highly functional formal set.

Sharp Looking Suit That Fits Well and Doesn’t Feel Overly Formal
Color: Light Grey, Size: 10
I ordered this set for a more formal occasion, and it ended up being a really nice balance between looking dressed up and still being comfortable. The first thing that stood out is how good it looks overall. The style is clean and modern without feeling stiff or overly formal. It gives that polished look you want for events, but it doesn’t feel like a traditional heavy suit. The fabric is lighter than I expected, which is actually a plus. It makes it much more comfortable to wear, especially for kids who don’t want to be stuck in something hot or restrictive. It still looks structured, but it’s easier to move around in. The fit was solid right out of the package. The jacket lays nicely and doesn’t bunch or pull in awkward spots, and the pants fit well without needing much adjustment. It looks tailored without actually being tailored, which is ideal. The full set is a nice bonus. Having everything coordinated, including the shirt and accessories, makes it easy to get a complete look without having to piece things together separately. Details are well done. The buttons, stitching, and overall construction feel decent for the price point. It doesn’t come across as cheap, which can sometimes be the case with kids’ suits. It’s also held up well so far. No issues after wearing, and it still looks good without wrinkles taking over right away. If I had one small note, it’s that you may still want to double check sizing depending on your child’s build, especially for length in the pants or sleeves. Overall, this is a great option for formal events. It looks sharp, fits well, and is comfortable enough that it won’t be a battle to get them to wear it. Definitely a solid value for a full set.

Overall, a really solid choice
Color: Light Blue, Size: 6
This suit is a great option for a summer wedding or any formal event! The linen fabric keeps it lightweight and comfortable, which is perfect for kids, and the overall look is really sharp and stylish. The double-breasted jacket adds a nice elevated touch, and the full 5-piece set makes it easy to have a complete outfit without extra shopping. Everything fit well and looked great for the occasion. My only small complaint is the tie, it’s fine, but I do wish it was a bit nicer to match the quality of the rest of the suit. Overall, a really solid choice that looks adorable dressed up, with just a minor detail that could be improved.
