Unfortunately I need to quieten the wife's 06 wrx down because she's ment to be using it everyday but she's not because of the noise. It's currently got a back box and that's it. Can someone advise the best way to quieten it without fitting a complete standard exhaust. I don't want it really quiet just quieter than it is now. Thanks in advance

 

Does it still have the resonated centre pipe?

A back box on it's own shouldn't be too loud if so..

 

It seems to just have a straight through pipe with a back box

 

Put resonator section nab in

 

Could always fit a exhaust bung for daily driveing then take it out for when need be

 

Bung or exhaust valve. Search eBay. I'm thinking of exhaust valve!

 

Mine is spot on and it's running Prodrive decat midpipe,backbox but a afterburner middle section with resonator.

The resonator helps reduce the droning noise that you'd usually hear in the cab whilst driving normally.

 

Prodrive bbox, I changed the centre section to a resonated one when I had a ninja back box it made no difference if it's decatted then it's all down to the back box

 

I used to have the Cobra Sport backbox with resonated centre pipe, nice sound but not overly loud. No drone at all in the cabin.

 

Norman Dog...That Cobra Sport...was that the road type, race type or track friendly type? Im looking for a Cobra but dont want ti too silent or too loud. Many thanks.

 

This is the one I had:-

The site didn't differentiate between road/race/track types when I bought mine.

 

Thanks mate.
