im not looking to put a muffler back on it im looking for literally high flow cat and tips has anyone done that or have that if so what kind of cat did you use and how do you like it

 

All high flow cats are regular cats as it is a federal law that they can not be altered. I found this out the hard way that it is a marketing scheme,

has any one put headers on a dakota ? now im thinking of putting headers on and then having someong weld up a cat back to it from there

 

Headers aren't a big deal on 4.7's because the stock manifolds are decent. Replacing them with shorties isn't really worth it and I don't think they make lt's for them.

 

summit racing .com has shortty headers for 225$

 

not really worth it unless you have a fully modded engine. cams, intake, interals. ect.

 

so sticking with the factory manifolds and running a cat back is prob fine for just superchiped and cai and eventually lift you think and yes i realize that lift has nothing to do with the performance but eventually it will be under more load trying to turn bigger tires

 

i have an 02 dakota 3.9L. I put in a throttle body spacer and i didnt feel much of a difference. then i added a cold air intake. the intake made the throttle body spacer whistle loud which meant more airflow with means more torque/hp. i also have a magnaflow catback done http://www.youtube.com/watch?v=mj6Wu9-xiz4&NR=1. im getting it changed for a different series which will make it sound about this but louder. http://www.youtube.com/watch?v=eEBeiAy5H8s&NR=1

 

tb spacers are worthless, they dont do anything for our trucks.

 

TB spacers are expensive paperweights,
