They worked and sound great pick up my 1/8 mile speed 1 mile per hour to 84 mph not bad for a 5900lb truck ! Gain about 20 hp just changing to JBA headers.

Very good looking system. Shipping was quick and got it installed within an hour. Looks great but it does almost stick further out than my hitch. Very good quality stainless steel and the pipe looks awesome. Sound is very good and isnt too loud to keep the neighbors up while driving by. I would reccommend this for anyone that is looking for a good quality system for a very reasonable price. I put it in a week ago and was getting 14-16 mpg and now am getting around 18. I did also put in aem cai.
