Best place is in the I-pipe. If you want it loud put it closer to the Y-pipe

I asked Speed Inc if I should put one after each header or one after the Y-pipe and he told me to just put one in the I-pipe after the Y. They put mine right before the over the axle pipe starts, there's a nice place right there so you don't lose any ground clearance right below the rear passenger seat. Make sure to use band clamps instead of the crappy U-bolt clamps that come with the cutouts.

I think you can actaully have flanges made on your cutouts and your I pipe so that you can take them out for tech inspection.
