WRX-S

[KARL KING]

Hi all

I've got a WRX-S Hatchback and was wondering if anyone can verify if it's the middle silencer that makes the car so quiet also any local club/meets to the rickmansworth area? 

Much appreciated

Karl

I think what Tony is trying to show is

 

On this diagram it's item 32

This is an expansion box which for MY10 onwards was replaced on some models with just a resonator.

As the UK wrx-s is a PPP'd (Prodrive Performance Package) car it may already have the 2nd cat removed and have a Prodrive backbox ??? so the next logical step would be to replace the centre pipe with a straight through.

Thanks Don ? I think prodrive left the resonator in on some models only tanking our 2nd Cat. But not 100% on that

If you have box that looks like a squashed water bottle then that’s the resonator

Cheers guys sorry well late reply ended up getting a vortex backbox from scoobyworld but am now thinking of getting a grimmspeed downpipe with sports cat and an invidia system!

Hi mate I have the same WRX-S with the Prodrive exhaust it is very quiet! Did your vortex make it sound any better? also didn’t think the vortex fit? But the afterburner was for the hatch?

Sorry yeah it is the afterburner sounds great on boost still quiet but I've still got the standard middle section on need to replace it really but then thought I'd completely change the whole system!

Hey guys still currently running the afterburner more than a year on lol 

had clutch & lightweight flywheel fitted plus oils shortly after the last post and this year has seen full service, cambelt/water pump/thermostat, plus under-sealing and white line rear anti roll bar with drop links! Also got the Killer b oil up pipe and baffle plate to fit in the sump! 
moving on from that was thinking of getting a cobb ACCESSPORT v3 and replacing entire exhaust system with a 3inch from cobb or invidia? 
any suggestions
