|The installation was not as easy as I was expecting. The exhaust pipe was to long according to the installation instructions. After parcel assembly and disassembly several times I ended up removing 5 1/2 inches from the exhaust pipe. After the installation was complete I was unable the tighten the clamps tight enough to stop the system from shifting. To resolve this problem I had to weld all joints. I finally got everything where I was happy with it. The sound is what I wanted.|

|Installed this on my Hemi Ram 1500. It has a decent rumble at idle and a good growl at low rpms. When you get on the pedal the volume is decent. I like the fact that if your on the highway cruising it doesn't drone in the cab. Overall a good product. If you want aggressive sound while on the gas this is for you. If you want all out loudness go with the outlaw series. It is a bit more agressive.|

|This exhaust sounds great but the bands that hold it all together are terrible. Leaks air like crazy and ended up paying $80 more to have it welded.... Be prepared to have this done. Once its welded it sounds awesome and please with sound! Prob would have it fabrivated with same muffler for $200-300 cheaper next time. Just my two cents!|
|ORDER was shipped on time, quality was great and the ease of how everything fit was right on mark, overall the experience was a 5 thanks.|

|They sound great. Instillation was easy and everything fit. The only problem was with the clamps! Had the same problem others has talked about. Clamps would not tighten enough to hold pipes secure. Used a impact wrench and bottomed out the threads and they still would not hold. After taking them off three times finally gave up trying to make them work went and bought regular muffler clamps. The ones they send are not cheep clamps but just will not compress the split on the end of the pipe. I'm 70 yo and installed them by myself on the ground (no lift) The hard part is trying to get the old tail pipe out without cutting it. If your on a lift no problem. I finally cut it to get it out. Other then the clamp problem a smooth and simple install. Watch the video of the installation before hand its on their site.|
