Hi I have a 2010 WRX with the PPP pack on it, i am looking to change the HUGE 23" chambered rear silencer on the rear of the car and was looking for some advice.

The car only has this one silencer on it at the rear from the cat back, but there is no burble from it at all.

I was wondering what silencer size I should put on that will give me the noise I am looking for.

Took it to longlife and got them to look over it and they have suggested a much smaller straight through silencer of around 12"

Does anyone have any input or help?

For some reason this shape WRX is just not as loud as the older classics that I am used to.

 

Anyone?
