Hey Im new here and I just got my first blazer. It's an 01 xtreme and I was wondering how benificial it would actually be to do headers and intake. I figure about 600-700 bucks for both new and I just dont know if it is worth it. Im not really looking to make this thing too radical I just want it to be nice and firm. Suggestions? Does anyone have like dyno numbers or anything backing up what they have?

 

the best mod you can do is put a better flowing exhaust on.
generally speaking, motors breathe better than they exhale. you should feel more gains from headers than from an intake.
