I ordered this for my 2010 Silverado ext cab. The kit arrived very fast!! Day after it shipped. Kit was complete and any backyard mechanic could install quickly and easily. The system sounds great and I noticed a power gain immediately. Had the loudness that you would expect with 50series mufflers, but not so loud that you would upset neighbors or be unable to hold a conversation easily inside the cab. Almost perfect for a person wanting the rumble without drowning out everything else. Only one problem... Took to have all seams welded and there is one section that crosses in front of rear differential drain plug. This section shouldn't be welded. I used provided clamps here so I could still have access to my drain plug. Awesome system awesome price!

I was most impressed with the ease of installation of this product. The product is well
engineered and does not require the installer to do anything special to get the job done.
Of course Chevrolet also did a wonderful job designing the muffler system that this product
replaces, allowing the installer to quickly and easily take the system apart. The only
requirement is that the flex tube between the catalytic convertor and muffler be cut. This
requires a fairy good sized saw-z-all blade to get the job done. Once the original system
has been removed, installing the new system takes a matter of minutes. The instructions
recommend welding the pipes together once final alignment of the pieces has been done, but
we have found that the supplied clamps are strong enough to hold things in place. If in
doubt, place a tack weld on each joint and call it a day. This will allow you to uninstall
the system at a later date, if required. You can also hang on to your original system and
bolt it back into place in minutes if required. You'll need to find an adapter pipe, which
should be available at your local auto parts store.

The sound of the system is as advertised and provides a nice rumble at idle and part throttle.
There is a bit of resonance in the cab, but this is part of what you bought the system for in
the first place so enjoy.

This system fits perfectly on my truck. Installed in a little over an hour. (Would've been faster if I had a hoist, ramps or proper jack and stands.) Sounds fantastic, sounds a lot like a magnaflow system but with a bit more grit. I would highly recommend this product!

Put this on my 2008 GMC Crew Cab. Product was great. Installed in 2 hours and sound is perfect. Not too loud and not too quiet. The only problem I have is the sound of the truck switching from v8 to v4 mode can get a little annoying. Not the fault of the product at all. It just makes the switching of modes a lot more noticeable. It also takes some time to get the tip position to match on the back of the truck.

I can tell the power gains immediately, put on an 2009 GMC 5.3L V8 and paired with a K&N Black Hawk CIR, both impressive sounding and quality, when you get on it, it'll let em know, when your cruising it's just a nice purr.

The sound Is great! Not too loud but adds a nice rumble. I would have given 5 stars but the clamps are difficult to get tight enough to stop any movement. You really got to reef on them. Other than that installation was easy!
