all depends on your setup... if your n/a do the ss/tc header and downpipe.
ya i think he meant SS/SC.I already have a ported manifold and catless dp but want an actual header/dp combo.then im getting tuned and nitrous
I have better than that on my stock manifold.I spent 2 days porting it out and compared it to a SS/SC ,mani and mine is bigger lol
