Just not a big fan of back pressure and restrictive flow. How come they don't make a kit for the automatic ?

To answer your question, likely because of the AFM valves interferes and would have to added into the kit which would probably double the cost. Don't know for certain just speculation based on what I seen when I tried to use them. I ended up sending them back and changing the entire X pipe.

Either way, It's a waste of time, effort, and money until your are making A LOT more power than stock.

Already been tested multiple times, the crushed pipe has absolutely no effect of hurting performance.

I agree but to a point, as some point in the build even NA, it will cause a restriction, sure it is at the rear where exhaust gasses have lost lots of their energy. My guess on a health NA engine with LT, heads, cam 3 to 10 HP. Stock almost zero, on a health FI build I can see upto 12 HP but we are talking engines reaching 900+ HP. Now if you ask me is there any power going from 2 and 3/4 stock size to 3" dunno about that one, even on 3/4 FI builds...
