[Mgs] Exhaust system

[Charley & Peggy Robinson]

I'e been rethinking this.  First, I used the term "front muffler" in my 
earlier post.  Actually, it's not a muffler; it's a resonator. It's 
essentially an expansion chamber whose purpose is to cancel out the high 
frequency exhaust pulses; the sharp barks IOW.  Some resonators have a 
shell within a shell with insulation in between to do some quieting; 
some don't.
Since it appears that the exhaust sound you object to is localized in 
the cockpit area, I wonder if your resonator might be cracked or 
possibly touching the underside of the floor pan or a loose connection.  
If not, increasing the resonator volume or its type of construction & 
insulation might be a way to go.  Just have to get the car on a lift and 
have a look-see.

I am thinking of replacing my middle “bomb box” section with the oval shape muffler and see where I end up.  If need be I can then replace the rear section.  I am planning to use mild steel connected to the stainless front pipe.
