And if the cats you removed were partially plugged up or fouled are whatever happens to cats then you will have reduced the backpressure by THAT much more. Put it on a dyno and see if its making more power.....would be nice to see what the MAF is reading at WOT to know if you are pulling more air but you would have needed to know what it was reading before the new mods.

 

Thanks...
