Default Decat too noisy

Hi All,

I just bought my car and love it. For blasts around country roads it's awesome and the noise is great but, at motorway speeds it's a bit too loud.

is there a way of turning down the volume without replacing the exhaust?

Cheers,
Craig

Hi Si,

Can't remember but, I have the invoice in the history of the car. Will have a look. Would a bung restrict the airflow or just reduce the noise?

contaxt "AA Silencers" who will make you a custom race silencer and cut it into the system. Considerably lowering the noise with very little loss of flow + you probbably wouldn't notice it tbh.

Thanks all. Will have a look into it. I'm still a little torn with if I should or not. Will have to go on a long motorway drive to see if that makes my mind up

Sound proofing? Will cut the noise but will add weight.

Seems like I've got a few options to consider. Good news that it seems very possible and hopefully not too expensive.

A bung is the cheapest option,and dead simple to use when ever you want imho.Yes it does restrict the flow ,but you dont notice it when your cruising along at 70+ mph on a motorway & the reduction in noise is worth it.The restriction becomes more noticeable when your accelerating up through the gears on full boost & giving it 'plenty' with the bung in.
