sam, If you have time this week I'd like to get on the dyno again and see what difference my full 3" exhaust makes over my 2.5" with a cutout at a 90* angle.. According to the butt dyno it seems to pull a little harder than before.. As far as the se-r and the si, i'm game but the si should be able to take the victory no sweat. si has more power and less weight. But should be a good time none the less. I dont think I will be able to make it to track day though.. I have someone waiting for me in orlando that night . I will call you this week Sam. I'd just like another baseline run ..little to no tuning unless its changed for some reason. And i'll try to find a way to attach the other tow hook..
