Nah I’m talking US spec cars too. If you look in a stock downpipe, there’s a catalytic converters between the upstream and downstream O2.

There’s also a second one after the downstream O2 within the downpipe body. I figure that’s there to just further reduce emissions even though it’s efficacy isn’t being measured by the ECU?

there is only one CAT in the US spec Downpipe

Anyone have a problem with getting the exhaust mount which is directly behind where the downpipe connects to the stock exhaust to line up properly again after installation? I'm pretty close, just not close enough. :) I'm doing it on jackstands which isn't helping any at all.

Just did this last night... Make sure the downpipe hanger nuts aren't fully tightened and the clamp holding it to the turbo is loose. Then a little elbow grease and a mallet should do the trick lol.

The interesting part about the stage 2 downpipe is it has a separate adapter to slide into the stock exhaust. So I can actually just remove that piece and leave the hanger nuts and turbo clamp on. I wonder if it's going to take some type of lubricant or something to get this blasted adapter on. lol I have a friend with a lift who has offered to let me use it tomorrow, so going to give it another try.

If you are looking for a downpipe that does not throw CEL, Active autowerks chatted is the way to go.

In terms of power, sound, and fitment, all proven brand will perform the same

We offer Acitve Autowerke, VRSF, CTS,etc...

A VRSF will give me a CEL 100% right? Is this CEL one that will chime and bother the hell out of me, or its just the light?
