Let me ask a stupid question here: Why not just run true dual exhaust?
I read some other posts about equalizing the tubes using an x or h pipe which makes a lot of sense - but the only dual exhaust pics I have seen are in the 2GR swap (Gouky I think?) It seems like a lot of unnecessary work to run a y-pipe and then back out to duals...
When I get my 1MZ swap done (should be next month) I am taking the car to a local custom exhaust shop. I'll take some pics and video. I'm planning on the Apexi N1 mufflers and an X pipe.
I think this Camry sounds bad a**
