2012 Tundra max cab. Very well made and simple to install. While it's night and day difference in sound, it's not as loud as some people are claiming. Granted the stock exhaust is virtually silent but this is how a big V8 should sound in a pick up truck. It's quite tame up to 1/4 throttle and gets progressively louder when you get on it. It has a nice rumble on start up and sounds awesome in a tunnel or a parking garage. It's noticable at highway speed but not obnoxious. My truck is from Texas so it is rust free and well maintained plus I've been working on my own cars for 30 plus years. It took me two hours to take the old system down and hang the new setup. I used silicone spray on all the rubber hangers and on the new clamp bolts. Also I used a DeWalt 1/2" impact. I did it on the ground on a creeper in the rain, it was extremely easy. Although it was a bit pricey, I've used Flowmaster in the past and have hundreds of thousands of miles of good experiences. I did snap a bolt on the tip clamp but that was just carelessness with the impact gun, fortunately they included extras. I'm not doing any performance mods or off roading but technically speaking increasing your exhaust to a large dual setup is essential and the first step. I wish there was an X pipe as the muffler is a simple two in two out but I understand that it's much more complicated to get an X stuffed underneath. All in all I'm very satisfied, it's very aggressive, turns heads and should last a very long time

Sat in my garage for two hours until I got home and then was up and running 2-1/2 hours later. Installed myself, without a lift on SR5 4x4 stock 2015 Tundra. Never done anything like it before. You'll need metric sockets to take the old exhaust system off and standard deep well sockets to put this on.Pros:- Comes with an extra hanger and rubber mount for the drivers side pipe since this is missing on stock single exhaust framework. Had everything need for the swap out.- No lift required for install on my stock 4x4 because it comes in several clamp on pieces.- Parts fit together nicely.- Have choice to exit the end tail pipes out the back or the sides.- Sounds tough and impressive at startup. Impossible to ignore.Cons:- No H-Pipe or X-pipe included for balancing/equalization. Each side is 100% independent. This causes "backrap" at times and makes for a less refined sound. For the cost, you'd think that could be thrown in. The 2-1/2" H-Pipe kit they sell ($70.00) wont work for the 2015 Tundra because the muffler inlet pipes are too close together.- Way louder than I had bargained for when you really get on it. Impossible to ignore. But honestly, now than it's in, I'm not taking it back out.- The two drivers side tailpipe sections are so long that they create quite the lever arm. Almighty torque has to be placed on the drivers side muffler outlet clamp as well as the next downstream clamp in order for them not to twist at the joints because of this. So much torque that you think your gonna bust it off. Flowmaster tech support suggests applying penetrating oil to those two clamp bolts before tightening.Edit 08232015: I was told that as the muffler aged that this would get louder; my experience has been the opposite. The system still is loud and unruly when you get on it, but at idle is noticeably quieter than when originally installed. Also, IF YOU PLAN ON GETTING LARGER DIAMETER TIRES they will very likely no longer fit where the spare mounts. The drivers side exhaust outlet is like a 1/2" from the spare tire. Solutions would be to carry a locked spare in the bed or go to a muffler shop to see if they can change any pipe bends on that particular pipe to accommodate the spare.

Installation was very simple. From unboxing, uninstalling stock and then installing this system took me 3 hours. Mostly because I didn't have the right fitting sockets and had to improvise.The Sound:Truthfully nothing I can say here is as good as hearing it for yourself...It is a deep sound with a low rumble while idling and accelerating normally. It growls at you when you start your vehicle. Step on it and it roars to life with incredible noise. You definitely need to watch YouTube videos to get an idea but they don't represent exactly how loud it is. Like others say, it's right on the verge of being 'too loud'. I could see where taking a road trip for more than 6 hours could get a bit annoying with that 'drone' rumble while cruising. But honestly, it's something you'd get used to after the first hour.It will definitely set off car alarms as you drive by as I've already set off a few.The Install:I have a 2015 Tundra SR5 4x2 Crewmax. As I mentioned, it took about 3 hours to install. My install has the pipes coming out of the passenger and driver side. I tried as hard as I could to clamp down the pipes that curved around the spare tire but could not get them tight enough to stop the exhaust from twisting out of position after driving (Driver Side). I ended up having to put a couple of welds on the driver side pipe to keep it in position. If you can't get it tight enough, find a friend w/ a welder as it only took about 5 minutes to do the welds. It still allows me to remove the exhaust and return it to stock even though I welded it in two places. The instructions were very clear and easy to follow. I did the install with the rear of my truck on ramps. Probably not necessary but nice to have that extra room. Make sure you have the deep well sockets and some open ended wrenches. I am used to working on vehicles and do most of my own work but even if you have no experience at all, this would be easy to install.If you want a loud, head turning, awesome sounding beast of an exhaust on your Tundra, I highly recommend this system!

I got to say, there is no other exhaust that sounds better than this. It’s by far the best sound I have ever heard on any tundra, I’ve tested 4 other brands.The reason of the 1 star…. DRONE. When you’re on the freeway, you cannot hear anyone talking in the car. It is so bad that after driving 5 minutes, your ears get plugged. A normal human being cannot take that sound everyday. Such beautiful sound on low gears and idle. Such a shame they can’t fix the drone sound on freeway.

Awesome sound, from the time I start it up till I shut it down the truck sounds amazing
