I have a 2003 Dodge Ram 1500 4x4 Offroad Truck. I love it!!!
Has anyone put on an after market exhaust system and air filter system. I want to put on a flow master and K&N Airfilter system for a performance and gas mileage increase, but I have heard that the computer chip in the 03 hemi will re-calibrate itself and the only noticible difference is the sound of the new exhaust system. Is this true? Has anyone heard of this. I read it on another message board. I forget which one.
Can anyone recommend an exhaust system and airfilter system setp that will increase Horse power and mpg?
Thanks for any replies.</P>

Thanks for the reply dansram....I will probably put a k&amp;n in and wait on the flowmaster.

 

I am currently looking into the availability of the Borla catback system. I plan to get this soon and I will post thoughts. As for intake, K&amp;N !!!!

 

Has anyone tried the Volant airbox system? A lot better looking than the K&amp;N. IMO. A bit more expensive though.</P>

I installed a tornado under my hood a while back. Its takes less than 3 min. to install, just pull off one end of your air hose push the tornado in the hose and then put the hose back on. It costs about $80 or so. It increased my gas millage by about 3 more mpg and it also adds horsepower. It says it adds between about 10 to 40 hp... i dunno about 40 but yeah it is a noticiable difference and the gas $aving$ paid for it after just a little while of use. I would say its worth if but check it out for your self with the 30 day moneyback garuntee!!</P>

Flowmaster part #17375 a complete setup for the HEMI....if your truck is a Hemi! Great sound! Sounds bascially stock at idle and cruising speed which was what I was wanting...put when you put the peddle down....it sounds awesome!
