I have DC sports 4-2-1 header installed on my 93 h22a1....I love it. Now,I cant say that i've dyno'ed my car, but myself and 2 other of my friends/fellow car entuisiasts could all "feel" a significant gain throughout the power band...
Shivers, do u have the dc sports header on you ride? or are u just relaying information that you've heard?
