#1 is NOT stainless anymore (hence, the new price)
#2 for some reason fits an S30 but not a 280ZX

If I was running 20 or more psi, I wouldn't be using the factory turbo.
I don't want a super loud exhaust either.
2) The 280zx doesn't have enough firewall clearance for a 45* bend without some kinda modding to squeeze it in. I'm sure some people have done a dp with 2 45* bends, but I just used 2 90* bends when I had Vildini Motorsports make one for me. It's definitely a tight fit with the 3" pipe.

2 90* bends as in an S. One 90 from the turbo outlet, the other to bend to exit the chassis.
