[Roadsters] Exhaust pipe diameter

[Kendall Williams]

Yup, what they said.
I replaced mine with 1 3/4"exhaust and it fit through
the x-member just fine.  I 
expanded the front of the pipe to fit on the
inside of the expansion pipe.  So 
probably 1 7/8"-ish, and that expanded part
just fit through my x-member.
I put a Magnaflow muffler behind the x-member
with no resonator, and I think it 
sounds great.  Not too loud, and not buzzy.
