Steve,
You say you "bark the tires at 100 mph" ! Wow!
May I suggest and demand that you DO NOT modify the exhaust!
I mean, if your barking tires in 3rd, I sure don't want to be responsible for your car doing donuts in third with the modified exhaust!!!!!!!!

P.S. OK, we did this once but it got lost in the shuffle of the new site. Within a week or two we are customizing another set of these. I will take very detailed photographs of the entire process and post it. How's that?
