Have only driven it in town - traffic so don't know about performance.
After I get it chipped maybe I'll beable to get some performance info.
But, it would probabley be useless as I didn't check performance before the mods.

Another point is I don't know who actually made the thing, it says Borla on the muffler & tips, but I didn't get it from Borla. I was waiting for Borla to release their system, but got tired of waiting, Plan on getting it chipped real soon and wanted to change the exhaust before I got it chipped.
