BTW, the ypipe is super easy.
I had a sho-shop ypipe w/ cat before my headers... the ypipe is a GREAT bang for the buck.
The ypipe is very basic - unbolt 6 bolts, take old ypipe out, put new ypipe in place, bolt it up. An extra pair of hands is always nice for alligning exhaust piping.
Good luck, and welcome again!
