i know this has probably been beaten to death, but i can't find anything in the search. i have a 2005 M7 153" that i just put a full D&D exhaust setup on (y-pipe, single pipe, and can), and is otherwise still stock, besides things like track change and a few billet parts here & there. how would you guys recommend i change my clutching to match this setup? as far as i know, it's still the stock setup for clutching, and the sled's at home right now, so i can't be sure on which spring is in the primary or secondary, or which helix is in the secondary. any help would be greatly appreciated!
