Dynod today on same dyno at Vinny Ten In Farmingdale Same 55 degree weather. 348WHP 281TQ

Removed the OEM Nismo Muffler and Added AAM Competition Axle Back to go with my AAM Midpipes.

Nearly 40 HP Gain for swapping out a Muffler on a NA Car! The tune was left the same.

We thought the Dyno was not calibrated correctly so we put on one of the Techs Cars that works there whose car they know consistently makes 325WHP on his WRX. They did a pull on his WRX and it read 322WHP... Which is actually lower then anticipated.
