[Roadsters] Exhaust pipe diameter

[Gordon Glasgow]

Moving the muffler back is fine.

A resonator changes the tone, certainly. It's easy enough to add one later
if you don't like the sound without it.

You can use 1 3/4" pipe IF you put a flex pipe section between the header
and the rest of the system. Otherwise you'll be chasing rattles and/or
broken mounts forever. These engines move around more than the guys at the
muffler shop think they do. Been there, done that.

Getting new exhaust this week.  I already replaced the manifold with a
header.
So just getting new from there back.

Questions,

Shop is recommending moving muffler back towards the axle, instead of under
drivers seat.  Is that OK?

Is a resonator actually needed?

It looks like the pipe on there now is 1.5" diameter.  I asked about going
to
1 3/4", and shop said no problem.  Does 1 3/4 fit thru the frame holes
without any mods?

Thanks in advance for replies.

I am off to clean the oil leak residue, since the shop won't weld with the
'fire hazard'
