Everything included is stainless. Sounds a little louder than stock but really clean and no drone sounds on the highway. I love it and so does everyone that has heard it.

I finally found a 2012 5.7 hemi ram r/t regular cab! And a one owner at that! I even had some money left to do some personal touches like exhaust, after looking and listening to several systems and owning 2 flowmaster systems in the past I decided on this one and I love it! When I start it remotely I can hear the distinct deep growl in the driveway. It's great lol. It has a solid sweet rumble to it after idling down. My neighbors don't mind it at all and one guy is buying a similar FM system for his Chevy. There is no cabin drone at all out on the road and you will definitely hear it when you hit the pedal. It's a great add on to a hemi. I'm not sure on mileage as I've not checked it, but I can say those miles Ive had have been fun. Is it worth 750.00? I say hell yes!

Let me start by saying that after installing the exhaust it sounds beautiful. My 2013 ram 1500 has a growl on start up like a momma bear giving her first warning to the predatory human watching from afar. Shes got a nice rumble when driving but nothing too loud so unfortunately I can still hear my old lady nagging me but at least I can hear myself think about where I went wrong in life. When I jump on the throttle though it's on like donkey Kong annnnd I love it. Only issue I had though on a serious note was one of the hangers got bent (in shipping I assume) so I had to bend it back after racking my brain as to why it wouldn't fit at first. I blame our wonderful postal service here in the states. After all the box showed up on my porch with half the contents falling out. But anywhere I like the product and would definitely recommend it unless of course you want a super quiet truck or something really obnoxiously loud to compensate for your small....lug nuts.

I installed this system in about 2 hours on my creeper truck on stands. (Having a cutoff tool to get the old system off helps). The connector pipe leaves nice room for adjustment, the muffler lined up to the pipes perfectly. Very adjustable to get it hanging right before clamping it all down. Fits into the OEM hangers, and easy to line up the chrome tips. I never give 5 stars ... but I came back from my first ride smiling. Great rumble on idle and roars when you stomp on it. Noticeable increase in power too!

I installed it myself. The installation was a breeze, although one of the tips didn't want to tighten down. It's a bad design with a flimsy bolt and nut, that won't seat. I took the truck to the muffler shop. They welded both of the tips on for 40 bucks. Definitely recommend you have the tips welded, so you don't watch them in your rear view mirror, flying down the highway

If your looking for something loud this isn’t the exhaust for you. It sounds good and has a nice rumble when you get on it. But it sounded like it’d be much louder than it is unfortunately. There’s no cabin drone which is nice if that’s what you like. But at idle it basically sounds stock, maybe a tad louder. If you want that muscle sound you have to add long tubes. But I did pair it with a K&N CAI and my gas mileage increased noticeably. It’s a solid exhaust. If you’re looking at add a nice rumble when you accelerate and don’t want cabin drone this is for you.

Missing several parts…most noticeably the rings and bolts. The box was retaped and very damaged. So double check before you start installing. Disappointing to say the least.

Installation took me less than 2 hours including removal of stock pipes. Clamps worked perfectly and extremely solid upon completion. I would have given 5 stars, however, the chrome ends proved to be harder to install than the rest of the system. I have broke 3 bolts trying to get them tight enough to not fall off.
