I want to put a comp cam (212/218) in my truck and keep the stock exhaust. Yes I know its illogical but thats what I would like to do. I actually want it to be a sleeper and thats my reasoning behind it. How do you think it will idle in my 5.3? Any noticable lope?

 

it should sound just like stock almost... espically going through the stock muffler

 

Thanks, thats what I was hoping. Well, just for a while though.
