I'm currently running the SLP Y-Pipe with CATS and I rubbed a hole in the driver side CAT when I hit a speed bump last week. I replaced the driver side cat with just a straight pipe yesterday. What would be the effect of my performance if any if i leave the straight pipe in place on the driver side and keep the CAT on the passenger side.
