View Full Version : RS3 Cat-back on an '01 SE?

I purchased a Roadster Sport 3 CARB-compliant cat-back kit, assuming (perhaps incorrectly) that it would be 'plug-and-play' on my '01 SE. The downpipe has a 2-hole flange, where the car's manifold has 3, and there is no pre-cat or O2 sensor fitting.

Any thoughts on this?

TIA :cool:

Send it back and get the correct catback

Part # matches their website, so I'm not sure it's that easy; but thanks.

I have a message in to Moss. I'm hoping it's something simple, like they sent the wrong downpipe; but we'll see.

Why are you replacing the downpipe?

The stock downpipe won't fit the RS3 mid-pipe and cat. (stock is significantly smaller diameter)

I finally found the answer I was looking for, and I'm happy to say it will work (now that I'm not turned around bassackwards with the components). The OE downpipe stays where it is!
