Anybody have any trouble w/ there O2 sensors after putting exhaust on or anything like that just curious?

 

Yeah the WSP Ypipe i bought (used) broke my front o2 sensor. WSP doesnt make this ypipe anymore though so Im sure its no longer a problem. Also they offered to have me send the pipe back to them and then they ended up sending me a part that fixed it. If you are getting a ypipe go WSP for sure. They are so nice there.
