So went to the Dyno the other day to see what the previous owner did. I wish I could take credit for the work but I cant. Anyway, CAI, BBK Long tube headers, BBK mid pipes and Flowmaster mufflers. I did put an air/oil separator on, so there's that. Unknown tune.

 

The dyno numbers are in the ballpark for the mods done.

 

Interesting the peak power is at or close to 7k, stock is closer to 6400-6500 rpms, and the peak torque is at about 5k (stock rated at the crank anyway is at 4250rpms). That must be the longtubes at work.

 

The LT headers appear to make the torque curve flatter by adding more torque either side of the peak. Though the maximum is near 5100rpm, it's more of a plateau from 4300-5100rpm.

 

ya, i was more interested in making sure the car was tuned and running well from the previous owner. looks like everything is running good. car feels great.
