exhust note

Post by **cadetchris** » Tue Sep 29, 2009 1:16 pm

as i sit here suffering with tonsilitis, i though i would ask those questions i havent a clue what the answer is.

so, my moggy has a very loud exhust note.
its on its second engine and a nice new stainless steel exhust, yet it still is very loud. its the correct exhust, but still very loud.

any ideas whay this is?

Morris Minors are meant to have loud exhausts, particularly on the overrun. That is what makes them sound so distinctive. Your new system will quieten down a bit when the soot accumulates in the pipes.
Provided you haven't got any leaks around any joints, get used to it.

that makes more sense now, if its ment to have a nice throaty exhust, then i can tell me dad to stop worrying about it.

The stainless exhausts ARE often noisy - the stainless steel 'rings' much more than mild steel. And as the insides rot away and the baffles come loose - it gets louder and louder!

I'm having a stainless steel exhaust fitted this week to the car I've just aquired as the old one was rusted through (I think it was the original from 1970) I hope it doesn't sound too bad, I chose stainless as I thought it would be a moneysaver in the long term, still will have to wait and see.

An exhaust trim that deflects the pipe downwards can help quite a bit.
Fitted one on a traveller I drive as the exhaust was exiting just in front of the rear bumper blade and some of the noise seemed to be reflected towards the front of the car.
Also they tend to be shiny chrome, bling bling

Yes - my Traveller also needed an exhaust 'trim' extension to clear the bumper blade. My stainless exhaust has lasted very well - just recently replaced it with a home-made 'big bore' exhaust - but it certainly became noisier over the years - but then the engine power output also crept up due to various changes! At the end - there was a kind of 'scream' from the tailpipe at high revs!

My Moggies frequently break wind! (Avioiding the 'f' word). Art always needs a beginning.

I am about to strip and rebuild a new engine for Blackie and can't wait to fit a 3-2-1 manifold and a stainless pipe! brum!

The stainless LCBs are 'said' to be prone to cracking. Best avoid!

What would be a better alternative?

I've got a Falcon stainless LCB and it is 2 years old now with no problems - Key is to make sure the system is not ridgidly mounted down the underside of the vehicle allowing the system to move without stressing the manifold.
