Thanks for posting the link. I'm a little dissappointed in the Y-pipe they used. Maybe I'll just keep the OEM axle-back, and have a custom rear straight pipe for "fun" use (track days, etc.).

Why would you be dissapointed with the HKS Y pipe. The oem has a flatten area on the Y pipe that the flow is very restricted.

It's hard to say how restrictive the OEM Y-pipe is compared to the HKS pipe. The HKS Y-pipe looks like the OEM front Y-pipe, so I imagine the rear OEM pipe was equally well engineered. Lexus obviously flattened and widened the rear Y-pipe so that they could raise the ground clearance where it crosses the rear axle.
My hope was that HKS would have emplemented a Y-pipe like one of these.
BTW, I realize that there isn't that noticeable difference in design, but the rounded split of the HKS Y-pipe will not be nearly as aerodynamic as the knife edge that the Burn's Y-pipes have.
