Hey, i just recently picked up an '07 2.5rs and I'm looking to gather some info and links on some good recommendations regarding a full exhaust. (from new UEL headers all the way to the muffler) Any help with this would be greatly appreciated as I am quite new to this car scene and not very knowledgeable on this topic. Located in Canada also if that helps in any way.

thanks!

Sorry that nobody answered your question before. So the 2006-2007 2.5i Imprezas got a different (more strict) emission regime than the earlier cars. That makes building an exhaust that both fits those 2 years and also passes emissions much more expensive than the previous years. All hope is not lost (if you are related to Bill Gates). You can get all the parts you need from here: Exhaust

Using the earlier 2002-2005 Impreza aftermarket exhausts does fit, but eventually the ecu will figure out that you don't have the higher grade catalytic converters necessary, and you will throw check engine lights and won't pass emissions. Even if you don't have emissions, the ecu will change how it runs (in a worse way) with the check engine lights on.

I have an 05 OBS. I got UEL headers from Pro Tuning Lab, I purchased Magnaflo high flow cat from AutoAnything (you may need an extension to reach 2nd sensor location on the cat) and I purchased Tsudo cat-back 2.25" from AutoAnything.
I now see that Tsudo makes UEL + CAT. If I would do it again, I'd prolly go that route.
All in all, my OBS sounds like a boat at idle. Great sound 👍
