Long Tube Header Dyno results & Photo

[richardholdener]

Here is the graph of the dyno testing on the long tube header. The three runs represent the stock exhaust system, removal of the stock exhaust (running open exhuast manifold) and then the long-tube header and 2.5-inch exhaust section. We ran a 2.25 section with no change in power. System will be mild steel, header will require custom mid pipe wich will be made to go with header and pricing for both will be near $550 (waiting for official production quotes). If we get 10 people wanting this (gains are impressive), I will make a production run. The system will need a secondary oxygen simualtor (ask cali) to eliminate CEL but it causes no problems with power or driveability. Also check out posts on NST dyno results and new NA power record.
