Sorry all for the multiple postings. I have posted befor, but this time my computer kept showing that "server full" page. I did not know anything was posting and my message never got to the post.

I just received a SS y-pipe from Warp Speed for my 03 Max. I went to my local muffler guy and we lifted the car. It turns out the unit WS sent me does not replace the pre cats. It bolts on under them. Does this make sence? I though y-pipes are supposed to replace pre cats. Does this make since?

 

Not only does it not replace the pre's and have some fitment issuses. It give little to no power. Look Here
