for the average setup, if one has to purchase the parts at different times due to wallet constraints, which piece would be more worthwhile to get alone? i wanna take price, and safety into consideration as well. for example, i was thinking exhaust first cuz i've heard of a few pple running internal wgs having boost creep when they upgraded their dp. of course most of these people prob have the full exhaust setup too. so i can only ask for your opinions as i have to personal experience. i guess since one or the other piece wouldnt match up sizewise, i'd have to use a reducer or fab something to make it all fit together while i wait for money to buy the other parts. just wanna know what some of you would do in this situation. thanks lots.
