Cat Question
 

I've done all my research looking at the old threads before I possted this, so i am posting it to see if anyone recently put one on or has any new input. I reallywanna go with the hi flow cat instead of the test pipe because in ohioo i have to pass emissions. so does anyone have a hi flow cat, how much did they pay, brand, and where did u get it. also does everyone have direct fit or universal.

thanks
