Just deleted cats on the car and did a full road tune as well as a dyno tune. The new numbers are 430.29hp & 388.58tq. Kept the air/fuel at 12.7-12.8 the entire run until the very end where I leaned it out to 13.08 by redline. Car is running 26* of timing at WOT.

I took some video of the car on the dyno as well. It's loud without the cat man. To view the video you must "right click save as"

Awesome results man. Did you have stock cats when you did that? Or did you go from high flow cats to none?

Either way sexy numbers :nod:

One of the first free mods I did was gut my cats....picked up around 12rwhp if I remember correctly. This was on a car with just intake mods.

Stainless works has another muffler to replace the loudmouth that compliments there LT's well. Just in case you get tired of the droning and loudness. For my system we put bullets where the RT cats were; eliminated rasp. They also make a nice x-pipe system for the GTO....

Great numbers too!
