I thought I'd update my April '05 dyno results. Last week I took the car back to the same shop that dyno'd it in April. Since April, I put Stan's Headers tri-y's, 2 1/2" pipes and Magnaflow mufflers on the car. N20mike was right about a better exhaust system.
Previous best was 351rwhp and 360rwtq. Last week's results were 382rwhp and 376rwtq. No other changes. Obviously, I'm pleased.
