ASM 70mm Single Exhaust -08 + ASM Header -07 Dyno
We just dyno tested the ASM 70mm Single Stainless Exhaust -08 and ASM Exhaust Manifold -07. All the runs were performed back to back within minutes of each other on the same dyno and same car at Church Automotive Testing in Southern California. The test car was 100% stock, OEM Cat, OEM intake, no engine mods, not even a radiator cap; as stock as it rolled off the assembly line. 4-5 passes were performed for each configuration and the median plot was used.
Results:
ASM 70mm Single Exhaust + ASM Exhaust Manifold -07 combo = 18.5 HP / 15.4 lb-ft Gain @ 6200rpm
ASM 70mm Exhaust alone (OEM Header) = 14 HP / 12.6 lb-ft Gain @ 5600 rpm
Not bad considering the ASM 70mm Single Exhaust is by far the quietest and most refined sounding exhaust available for the S2000 at the moment.

Does this mean, this exhaust gain more than the J's Racing 70RR exhaust?? 70rr usually gain around +15hp... with that's with cat... ASM without cat will probably be another 5hp ??
