    Welcome to the site. Check out the Performance and Fuel section as there are multiple write-ups on both topics. The exhaust is really going to come to personal preference. I know that doesn't help a whole lot, but it's true. We're trying to gather up as many videos of members trucks as we can so people can judge what kind of sound they want.

    Again, welcome to the site and look forward to hearing more from you and seeing your truck.

    Welcome to the GMTC Foxrider, good to have you aboard. Well, I think the exhaust kit is a matter of taste but I went with the Magnaflow. I love the sound, no cab drone and it sounds great without being too loud. As far as the gas mileage, I did the K&N air intake, Magnaflow exhaust and an Edge CS programmer. I am getting 17 and 19 but the best way to get good mileage is to go easy on the gas pedal. I use the cruise as much as possible. Hope you enjoy the site as I do.

    There are a lot of good exhaust companies out there, but it is tough recommend since the sound is so subjective. I may like one while you may hate it. That said, I would listen to some videos or sound bites of your truck to get a good idea of what you want. We have lots of helpful articles, videos, reviews etc. on our site too!
