SC Exhaust note

My Ser 1 SC has the two muffler arrangement. I replaced the rear muffler and tail pipe when I first got the car. Now I've rebuild the engine it still sounds very 'tinny' when accelerating. No manifold leaks or loose damaged heat sheild. I'm confident its the front half of the exhaust system. Wondering if this is common.
Can I improve it by replacing the front muffler with a resinator.
 
Are you now stainless steel? These can sound not at all nice until you get a good coating of soot in them.
 
I’ve got a similar noise which I put down to a loose baffle or other innards in the rear silencer / muffler.

It’s the only one in the system so can’t be anything else :)
 
Isn't there a sheet metal part in the intake manifold that can get loose and cause rattling too?
 
Hi Team, Thanks for the suggestions, Not stainless, its an ageing mild steal system. I have previously checked the inlet manifold.
 
Hi all, I've finally got down to where the tinkling noise on acceleration was priority. Although it looked fine from the outside, I changed the resonator and its made a huge change to the driving experience. Not only has the tinkling gone but the car is wisper quiete at speed (except for the passenger's door seal). Apparently the glass wrapping inside the resonator isn't made to last 50 years!!!
