Hey, I got this test pipe when I bought a header/dp from another member here. I needed at least one cat in my exhaust so I ditched this and went with a high flow cat. It's an RRM 2.5" test pipe for the 02-03 Lancer. It replaces your second cat and has an o2 sensor bung already. And if you still have your stock header, you shouldn't throw any CELs. This bolts right onto the 02-03. To fit to an 04+ you need to have a custom downpipe made because it's a little different. The picture is how it is now, but I'll be taking off the chopped up stock exhaust pipe sides and it doesn't come with the o2 sensor hole plug, I still need that.
RRM sells it $69 new, so I'll sell it for $30 plus shipping since theres nothing wrong with it.
Message me or post here if you're interested. Thanks
