Are you guys satisfied with your y-pipes... I've been thinking of getting a Cattman y-pipe but after hearing problems about stalls, check engine lights, ETC... I'm kind of confused.. Should I wait until they completely master it so there aren't any problems?

 

The only thing that I would call a problem with mine is I have a little rattle when I am stoped in drive gear. I can only hear it when I am next to a wall or something but thats it, the pipe is great!!!!

 

No major problems with the y pipe.

Minor problem(s) that I can think of right now:
1) Y pipe would rattle once in a blue moon when I start the car

 

No problems with my y-pipe to date whatsoever.
