Not much really.

Sorry about the broken photo, fixed it.

The H-Pipe conversion is the best bang for the buck.
Why spend the same or more money to have less power?
Both are Cali legal so just get the better of the two (H) and be very happy with the results. :)

the v6 exhause is stock like that? thats nice if it is, and yeah I would def do the H pipe one, i heard dumb stuff about the Y on top of what all you guys say.

Yeah, its really easy to modify to a true dual exhaust with that kit.
