RE: exhaust leak
hmm...i dont see anything on the mopar performance website.
this is an odd situation, i think...before the new pipes went in, were you having a problem at all? if not, i would think that the gasket surface on the new pipes is somehow irregular. what type of material are the gaskets which are you using made out of?
lots of companies make "high performance" collector gaskets, but they are usually for headers. do you know he inside diameter and the bolt pattern? if youre having problems, i would recommend a copper collector gasket, but ive not had manifolds for so long, ill need as much info as you can provide before i can advise properly. also, once i find out exactly what you need, i can check to see if mopar offers a performance set, and i may be able to get you a better price..let me know.
