Straight through exhaust 02 WRX wagon advice


Recommended Posts

My mot tester just so happens to be one of best friends. Had fiesta st before this which was totally straight thro n tht was ok

N if it's pretty easy wouldn't be a headache to change for mot really.

Would the downpipe go all the way to the back box or would I also need a new centre pipe??

The exhaust is 3 sections, Down pipe, centre pipe and back box.

One the standard system both down pipe and centre pipe have cats.

In a cat back this is normally a straight through centre pipe and a larger bore back box.

Look under the car and when looking at the centre pipe it should be a straight through and not have a bulge for the cat.

A decat down pipe will fit regardless of the centre pipe having a cat or not. Just make sure it's the correct bore as you can ger 2.5 and 3" bore.

Sorry if teaching granny to suck eggs :)
