    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?

    Yes, a tube in the insulator between the carb and the manifold.

    Hi Team, Thanks for the suggestions, Not stainless, its an ageing mild steal system. I have previously checked the inlet manifold.
