Seems like everyone totes their performance parts to be the best. I have a 2004 2500 and like the idea of adding performance parts for towing. Looks like there are quite a few companys selling electronics upgrades and more than enough companys selling exhaust systems. I never go the cheapest nor the most expesive. Usually the middle of the road. I do however like the sound the stock exhaust puts out. Don't necessarily like some of the louder aftermarket exhaust. Word of mouth is a good thing. Any helpers ? Thanks.

 

hey the quad xzt is a good little box that you dont have to worry about with pressure and gauges. adds 65hp and 1-3 mpg. theres some in the classified if you dont know what im talkin about. brand new their about 300$. good luck

 

Edge's EZ or the Van Aaken smart box are great products for conservative horsepower gains, VA+75hp 200TQ/ EZ 70/220.
