was installing a new engine in my 2006 Dodge Ram 2500, priced factory dodge dual tail pipe system with employee discount was going to be 915.00 dollars, it wasn't a hard choice to go with the Flowmaster package!!! the sound difference between to 2 systems is not even close!!! this is my 3rd Dodge truck all have had the exhaust systems upgraded. The American Thunder package is the best system and value I have chosen to date

almost perfect

I'm mechanical lyrics inclined so this wasn't difficult. The kit comes with all your going to need except the I structures could've been more detailed in one or two areas.The mid pipe triming, I'd be more detail ed and tell people which end to cut, it wouldn't be obvious for someone's 1st time. And the extra hanger for example "crew cab" as I'm sure some will mix it with the "quad cab". I suppose that if these only two quirks that I have held anyone up, they shouldn't be doing their's.1hr20min.

I am very happy with the flow master exhaust I received. Easily Installed it in my buddy's driveway in about an hour the only hard part was removing the stock pipes. The kit comes with parts for straight rear exit or side exits which I think is nice if you ever wana switch it up. I love the sound very throaty and decently loud I wish louder though I had the truck straight pipe for a few weeks and got used to that but this sounds much cleaner in all i would recommend to anyone

Installs easily with clear instructions. Sounds good and looks good. Kit comes with 2 options,either straight out the back or side discharge.Truck may get better MPG, to early to tell for sure. Pipes were bent perfectly to go around spare tire and all necessary hardware was provided.

Ease of install and sounds great

I had this exhaust installed at a local performance exhaust place so that I could have it all welded together and they said the install was easy. Took them about 1:45 minutes. It sounds great, I feel like there is extra power, and by fuel mileage indicator has gone up by almost a full MPG. Awesome exhaust. Thanks Flowmaster for making something for my truck that no one esle seems to have done!!!
