The media could not be loaded. Sounds amazing. Not to loud but has a great tone. Little to no droning going down the road. Instructions were ok pics were blurry.

Granted it sounds best in v8
A lot of people said this exhaust droned in v4 mode and I haven't really suffered from that now a couple weeks and 1500 miles later. Granted it sounds best in v8, but I don't get the droning at all. Exhaust sounds great, looks great, clamps were fine (which I read about on another site) installation was a breeze. All in all great exhaust. I suppose the only downside now is that I can't keep my foot out the truck to hear the 5.3 scream so my MPG has gone down. Oh well, you win some you lose some. ... show more

Great sound but could use better instructions.
Very Mellow but throaty sound. It was more mellow than I was expecting. Its civilized and throaty (not obnoxious) when going through downtown city streets. But it gets louder when on it. But not too loud. I think it's perfect. I wanted an exhaust that was fairly quiet in parking lots or at a stop light but let's people know you're rocking a V8 when pulling away hard. This exhaust is perfect for that. I'm happy with it. Installation was a bit tricky. The tolerances between some if the flaired pipe ends were a bit loose. Especially the last piece of pipe that the exhaust tips slip on to. It doesnt have any hangers or any other support than the clamp. I couldn't get the clamp to crush the pipe enough to stop the pipe from twisting down when it heats up. I ended up taking a hacksaw and cutting 4 slits in the flaired end of the pipe so it would have room to shrink when tightening the clamp. This modification seemed to work. The directions could be clearer and especially more detailed. I had a heck of a time figuring out how to install the exhaust hanger on the driver side. The description is not detailed and the small black and white picture was very hard to see to figure it out. I'm still not sure of I have it installed right. It's on ther bit the rubber connector seems to hang sideways and not vertical. The clamps are ok. I can see why some reviewers said they were crap because they aren't tight on the pipe. It think it's due to the loose pipe tolerances that I mentioned earlier. Also, use hand tools to tighten the clamps and not an air tool. That could strip the threads. Overall I'm happy with the exhaust system. ... show more

Perfect for my truck
Pretty loud on startup which is awesome, then has a nice growl when driving, not too loud. Sounds okay with AFM and in V4 mode.. the instructions say this muffler is made for vehicles with AFM mode. The instructions are poor.. it’s just one image and I had to look up how to install the driver side exhaust because my truck came stock with a single exhaust, but it did come with the parts to install it on the driver side. Overall, very happy with it, it sounds like a truck now. If you don’t like the V4 mode noise then I suggest buying an AFM delete for your OBD port. ... show more

Sounds great easy install worth the buy
If you follow the directions it's pretty easy to install and sounds great. Installed in about 2 hours no lift did use jack stands like suggested. Shipped fast great price for a quality product

It sounds good. It's not too loud
Installation is straight forward. It sounds good. It's not too loud. My only issue is with the clamps that come with it. Some of them stripped put before they even got tight enough to hold the pipes together. I even with a box and ratchet wrench the clamps stripped out. Luckily the local auto parts store had heavy duty exhaust clamps in stock. I would highly recommend that you order heady duty exhaust clamps to go with this. You'll need four 2-1/4" and one 3". I thought the 4" exhaust tops would be too big but they look good under my Silverado. Would have given this 5 stars if it weren't for the subpar hardware. ... show more

Sounds good on 16 Silverado.
Sounds good on my 16 Silverado. Only thing I did notice is when you are in four cylinder mode and feather the gas pedal it gets a lot of drone in your cab. Other than that great product for the price.
