Here is a video clip of some guy on youtube with his exhaust system. I want my truck to sound exactly like this BUT, will it improve my MPG? and also if you know the name of the products or where I can find it, please let me know. I've been looking online for a while now lol.
Hey buddy sorry it took me so long to get on here and respond. That setup is a JBA Y pipe and a 3" Dynomax Bullet muffler bolted on...My advice do NOT run it like I did dumped in the middle of the cab...Drone was TERRIBLE and 2-3 stops by CHP convinced me it was time for something better...
The JBA catback system was fantastic right out the get-go, though swapping it with a dynomax will give you relatively the same sound without the terrible drone.
As far as mileage no, you'll be stomping around so much it really wont do anything...though if you pick yourself up a Cold Air Intake and drive like a grandma you could probably squeeze a little bit out! :teethmast
PM me if you have any more questions man,
