Only had time for one quick pull, but I'm pleased with the numbers! 339.8 HP/342.2 TQ. That's compared to 309 HP/310 TQ in 2003 through the stock manifolds with Flowmaster cat back. The Flowmasters sound even better throught the headers!!!

***EDIT***OOPS.....I just went through all of my files on the car, and the first numbers were through the stock exhaust (NOT THE FLOWMASTER CAT BACK)***

Headed to VIR next weekend for her first event!

Although Im glad to see the increase in hp do to headers and by no means want to burst any bubbles but 309rwhp tells me there's a problem somewhere. At the very least a healthy stock LT5 should put down 325rwhp. Mine put down 340rwhp 335 ft with stock manifolds and just an old Borla. Mine once dynoed at 309 only because my drivers side cat decided to expload and exit the exuast and Corey took his foot off the gas. Corey said it was actually pretty awesome. A big flame shot out the muffler and honeycomb substrait hit the wall. Lol!
