That looks like a full race exhaust system... your neighbors might just shoot you if you decide to go home really late

I would question the stock hp at 318.8 never seen a number that low on any dyno

I'm thinking, poor dyno operator + cooler temps could have something to do with a 40 increase.......
NOT saying they don't know what they were doing but from a Dyno operetor's point of view:
We have many factors to enter which would/could allow the number drastically change, if one wanted.
I bet it helped out with at least 20+!!! Sounds Awesome...

Even on a Mustang, those stock numbers seem kinda low. I have to echo what Adam@Autoscope said...
