cos im stoopid, can someone explain the exhaust set up on a bugeye my01 WRX?
I want to change bits, got a magnex b/box, but not sure how many other bits are in the exhaust total.
Is it (from the rear)
1.b/box
2.centre pipe
3.cat
4.up pipe
5.down pipe with cat to turbo??????
as you can see, i need help.


regards, cliff

 

From the rear:

backbox
long centre
small cat centre
downpipe
upipe
front manifold

All of the above can either be done in 1 go or a piece at a time; though to save money have the upipe & downpipe done at the same time.

 

cheers for that. just 1 last question though. which bit carries the 2nd cat?

On WRX's 3 cats

Upipe - 1st cat
Downpipe - 2nd cat
Small Cat pipe - 3rd cat

I initially thought they had done away with 3 cats on the new shape WRX's though after numerous decat systems they are all still there......

Of course for the sti's only 2

Downpipe & Small Cat pipe
