How can a y pipe possibly have better flow? Had you removed the left and right cats on the prior car? Think about it, if you take two pipes and put them together going into one pipe 1/3 to 1/2 of each of the small inlet pipes is being cut off at the joint...right where the two are coming together and piling their discharge onto eachother.

Dude, your not listening.....What I was comparing was using a
large capacity single inlet cat with a Y pipe made Compared to a dual inlet Cat like what comes on the car stock. Even if both cats are hi flow versions, the single inlet is more effeciant then a dual
inlet.
I wasnt comparing the ypipe set up with a true dual kit.
Im not a fan of a true dual kit on these cars anyway..
The hp gains are so marginal on both systems its not worth it to me to add more pipe and incure more cost.
You also lose alot of low end torque with a true dual kit in most cases.
