I have that setup and if you look at the driverside pipe you wouldn't even ask it's almost flat. Put it on you won't be sorry, except for the drone but that mostly comes from the lm.
I like the sound, all of it, sounds like my old 68 firebird.

Not worth it. People have swapped that y-pipe and gained nothing on the dyno. Save you money for other stuff.

Yes it's flat, but it's also very wide and flows at least 'ok'.
The SLP Y pipe is generally considered not worth it, especially when paying list price for a new one.
