Well engineered good quality product. It took more time to remove the old system than install the new Gibson system. Suggest you use a saw-all and cut the old exhaust pipe in several places rather than loosening the clamps and trying to pull the pipes apart. I was disapointed in the tone of the exhaust. Not much different than the stock exhaust note.

This Gibson s. steel system was a little pricy, but it looks much better then the stock system and is much more free flowing. The system sounds good and has a mild increase overall. The install was very easy with no problems. It's too soon to report much in the way of performance gains, but the gas mileage seems better. I would recommend this system if you have the money and like tinkering with your truck.

Great system for my truck

Just had this installed, it is straight forward enough to install yourself but it is just too cold this time of year. The system has a nice deep growl to it but is not overly loud. The stainless steel will hopefully keep this from rusting up for awhile. Overall a nicely made exhaust kit, though I would not expect to get any significant power gains from it.

I ordered the Gibson Stainless, single outlet system. Components are good quality, good welds. Fit pretty good, flanges lined up well. I used new gaskets just to make sure of no problems. Had to bend all mounting points to get fit as I wanted it and had to clock the muffler to about 2 o'clock to get the best fit. Other then that, no problems. Maybe because mine is a Nismo model. Sound is definitely louder, but not excessive. No resonance in the cab at cruise speeds, quiet then. Only small performance gain, little disappointing for that. I ran the truck at the 1/4 mile dragstrip before and after the install. Only a 1 mph gain, but 2 tenths in time. I also installed a Volant cold air intake at the same time, so I can't separate the gain from each. Truck lost a little from the very bottom end but midrange and top end feel stronger. Should be expected with the large pipes. I've been running it a month now, apperance holding up very well, diddn't hurt gas mileage, maybe 1 mpg better....and I check every tank. Overall I would recommend the Gibson system.
