Great Muffler, Easy install, more horsepower

I am very happy with the quality, simplicity and ease of installation of this muffler on my 06 Dakota (V6). I noticed a great deal of horsepower and torque gain immediately. Modified from 2 1/2" and 3 mufflers to 3" from cat back (Cat integral in headers). It improved the sound significantly though still nice and quiet in the cab. I have yet to verify gas mileage. Initially, it seems i lost mileage, but that is likely to be a fluke.

Wanted some improved power while towing my 24' travel trailer and this exhaust system was just what I needed!! Installed in no time, hardest part was removing the stock exhaust. Truck runs super at the lower RPM band and gas mileage seems to have improved somewhat, I'll know more about that aspect in time as I have only made one trip with the trailer since it was installed!! Gibson, Thanks for a great product!

I ordered the aluminized steel version to save a little cash. I cleaned all of the oil and dirt off of it and coated all of the exhaust with ceramic header paint and followed the directions for proper curing on the can. The old clamps needed to be cut off to remove the stock system. The new system slipped on perfect. even the distance that the tail pipe hung down from the quarter panel was perfec (i'm really pickey). The sound was exactly what i was looking for. much more agressive low tone at iddle and barks even more when yopu lay into it. it is a little louder in the cab but not too bad. too early for MPG difference but does have a lot more throttle respose.

The old system came off fairly easily but my truck is only 2 years old so it has not had much time to rust. New one went on with minor trouble. Hardest thing to do was get the new pipe to clamp tight to the old collector. I recomend getting an exhaust crack and joint sealer before you start and apply it to all the pipes as you assemble it.
