Picked up a great ram 50 over the weekend. Overall the truck is in good condition however right off the bat I know the exhaust needs to be replaced (muffler and a few other places have rust holes) and the truck has a bad hanging/high idle (especially when it warms up to operating temp).

I'd like to eliminate the EGR/smog system for a few reasons:
1.) I dont have to pass smog/emissions with this truck where I live
2.) I suspect some part of the smog/EGR system is responsible for this hanging idle and why keep it if I dont need it
3.) If I have to replace the exhaust might as well replace the header as well to elimnate the smog system it has built into the stock exhaust manifold
4.) Clean up the engine bay and uncomplicate things
5.) whatever this hanging idle issue is I think its hurting my mpg's..which is never good!
Mostly 1 and 2..

So has anybody done this? More importantly, can I do this without upgrading to a weber carb and keep the stock mikuni by just plugging ports without loss of functionality/performance?

Any info is much appreciated!
