yellowzx you won't be disappointed. To each there own but for me I love the sound plus a boost in performance is great to. I thought there would be a small gain in performance, and I was wrong, it was a BIG gain. I know it breaths better but the new chip for the ECU must ramp up the igition curve because it revs alot faster and it has an awesome throtle response.
