just a quick question, how many cats does a wrx exhaust have? i know there is one on the down pipe but there is a box just b4 the centre section which ive been told is a silencer. is this true?

 

A year would help, classics have 2, downpipe and centre.
new age have 3

 

its a 94 m reg

 

you'll have one...............UK cars have 2...............

 

My old MY95 WRX had two before decatting - downpipe and centre?

 

i think the centre one is just a silencer,i was told

 

how many on a 52 wrx an how many pieces is the exhaust

 

The parts of a 52 plate WRX exhaust are:-

Uppipe (1st Cat)
Downpipe (2nd Cat)
Centre Cat Pipe (3rd Cat)
Centre resonator pipe
Back Box.

This picture shows the all sections apart from the uppipe.



Hope this helps.

 

good that m8.....but wheres the uppipe???........i'm thick you see with this stuff

 

The uppipe is connected to the turbo.

 

thanks for that. which 1 is the best 1 to leave in then if im gonna take 2 out
