It would make it louder i'm sure

The exhaust note will be louder, by how much depends on the rest of the system. Other thing is that you should be able to hear the turbo spooling up much more clearly/easily, like a mild whistling. It's cool

Just re-read post; you should be pretty loud with that set-up.

It will sound like a jetfighter taking off

Lots of raspy air action... only way I could describe it when I had my old WRX done. Lots of turbo noise as well which sounds awesome

Major pops and bangs!!

Yep, gonna get much louder.

Sorry to hijack, but i've got a full stainless and was wondering if I got a de cat would I need to have it mapped??

GazTheHat

Some do, some don't, but you certainly wont maximise the gains without one.

mine sounds the same mate

Mine wasn't a great deal "louder" as it were but it did get a much deeper tone/burble and at high revs you get some great pops. The turbo sound is more audible even with a recirc DV.

mine sounds the same mate but its not blowing ,its just pipe noise,you have nothing to deaden the noise with now seen as you have removed the cat so in theory its just like blowing down a piece of pipe.
