i think crucial might be a-lit-tle-jeal-ous, thats alright i understand, if i had spent that much money on a header and exhaust and only ran a 15.82, all we did to his car was take out some weight and tuned it. you guys no exhaust and headers arent necessarily the best for your cars, play around with some diameter changes in your intake system, you can create pressure pulses that will help your times a little. their are other cheaps ways to get good times also, just be creative and play around with home depot stuff.
