I'm not sure, but I think around 250hp, 275Tq to the rear wheels. It looks like you are putting down decent numbers for the mods you have.

I just bought a set of the OBX longtubes and they look nice. They are heavy metal, not thin and cheap feeling. The cats are not really cats though. They are straight through with perforations around the inside like a resonator or glasspack. But, they look like a cat on the outside. The flanges look nice. I caught some flack on SilveradoSS.com when I asked about them, but for the money, heck, I don't care. I can't wait to install them. Oh yeah, they come with the block off and everything to bolt right to the factory exhaust, except new header to head bolts. They would have been nice.
