Question Cutout question

I have done some reading. I just am not sure if I want to go 1 cutout near the end of the I pipe or go 2 cutouts. 1 being each side of the 3' Y-pipe. Has anyone gone either way. Susgestions are very welcome. I am running LT, ORY, and aftermarket muffler and stock piping for catback for a little back ground info.

I went with dual cutouts and McCord MPP2's in the y-pipe. On the first trip to the track with them.. I picked up 3-4 mph.

I got the single too in front of the rear axle, but it drags sometimes because of my Bilstein suspension. As soon as I move back to VA and get long tube headers (if they'll fit) I'm going with duals.

If you do run dual whats the best placement for them to maximize the performance?

Right behind the headers, before the cats.

I love the sound of dual cut outs right after the headers.
