i have a 2002 honda rubicon. i am considering changing the exhaust to a big gun or a supertrapp. does anyone have any advice as to wich is better? and what kind of hp increse i will recieve, low end or high end, ect. i will be adding a k/n filter kit and a k/n carb jet kit as well. thanks and safe riding to everyone.

 

Get the HMF with or without a quiet core depending on how noisey you like it. Exelent quality and it comes with a much better warrenty too. you will see more low/mid power gains than highend gains but believe me it's got more power from bottom to top. I have heard Big Guns don't hold up (rivits popping out and that sort of thing) as well as some other brands and the supertrapps get clogged with mud in the tunable disc's but that may not be a factor to you.
