Default Monte SS Dyno

I went with my buddy to dyno his Monte SS tonight at Backwoods Racing in Midland, MI. He ended up putting down 257hp and 337 lbs tq on a mustang dyno. The converter was unlocked. Turns out they are a pain in the *** to keep locked up on the dyno. The tuners were fighting that computer every inch of the way for 4 hours. The cars mods are a descreened maff, full exhaust up to the manifolds. At high rpm a huge vacuum forms in the intake manifold taking away power, but the K/N cold air on the way should take care of that. So the tuner said. I will have a dyno sheet, and video up prolly tomorrow. Some track times after may 11th as well.

That was a nice sounding exhaust, what kind of system is it?

I think he just took it to a muffler shop, had them put bigger piping all the way up to the manifolds, eliminated cats, and took out the resignators.
