Dynojet comparisons of 134DD Megaphone Exhaust with full Termignoni race system:

The first chart above shows a direct comparison of the full Termignoni race system in blue and the 134DD system in yellow. The Termi system was tested on our 1098DD with the Termi race ECU, and the 134DD Megaphone was run with a Nemesis ECU. After a lots of dyno time we developed a map for the Nemesis ECU to perfectly match the 134DD Megaphone (this map is available for anyone with the Nemesis ECU). The combination yielded a significant horsepower and torque increase across the RPM range from 14 HP & 6 ft/lbs at 6,000 RPM for muscle out of the corners to 6 HP & 4 ft/lbs of peak power for the straights.

To demonstrate that most of the HP and torque gains are a generated by the 134DD Megaphone, and not the ECU, this second chart shows a comparison between the Termignoni race system with Termi ECU versus the 134DD Megaphone using the Termi ECU. A small increase is due to our extensive dyno work mapping the Nemesis ECU, but most of the gains come from the 134DD Megaphone's unique balance of breathing and backpressure. Either with the standard ECU or our custom-mapped Nemesis ECU, the 134DD shows a significant increase of horsepower and torque across the RPM range - a testament to the flexibility of the pipe even when the ECU isn't specifically set up for it.
