Well, the main reason I was asking is because I'm going more for sound rather than performance. I wont have the funds to upgrade my exhaust until August (saving up for the Akra stainless steel ver.). I thought buying the DP first will hold my hunger over for the sound I'm craving.
But I suppose it's not worth the hassle if the warning light is on without the tune. I'm one of those paranoid people who flinches at the sight of anything going wrong with something. Usually with things I have little to none experience on. In this case, BMW and modifying cars in general.
Would the general consensus be tune > exhaust > DP > FMIC > meth > everything else?
