I did take interest in the cut out video, it for sure showed there is an ideal spot for cut outs...many street guys will just do it for sound not realizing it is a hp loss but sounds "cool"
The test I'm interested in and have never seen is the X pipe vs the collector extensions

I'll look later but i believe pipe max says around 18" also, but that is from where the primary pipes end in the collector and not 18" from the end of the collector!
