Look very good, but what you do with sensors?

The headers look great, but have you thought of running a dual set up instead of a Y-pipe convergence?

I know my 2000 will allow it, but shortly after, they went to 3 O2 sensors.  Mine only has 2, both before the main cat, nothing after.

If you went dual, you could drop down on tube size, and this will help maintain backpressure and should help reduce the sound.

Nice bundle of snake you've got there. If you follow the above post and run dual all the way back I'd suggest an H pipe to connect the two. My sound driver is fubar-ed so I wish I could hear the vidio. Looks like it was pulling pretty hard though, was that dyno set up to duplicate the weight of the vehicle to better test real world acceleration numbers? How close are those to being equal length?
