Hello everyone! I want to upgrade my car's exhaust and intake for a nicer sound. I know both of these items have nothing but positive reviews and I was wondering which I should buy first? At this very moment I have roughly $300 to spend. The GTR is $700 plus shipping and Option 3 CRABS is $175. Should I save up to get the GTR or go ahead and get an STD? I can't decide and would like some help Thanks everyone!
