Hey, I hope this hasnt been asked or answered anywhere, but I wanted to know if the works filter will be compatible with the 2009 lancer models?

Also whats involved in that installation?

I really want to keep my car as stock as possible but the air filter seems basic and wouldnt void the warranty? Does it give any noticeable increase in HP?

Also I am kinda considering an exhaust but would want an extremely low key axel back. The works one seems a little louder then I would want, does anyone make one more quiet that still give a performance boost?

 

Should be. I highly doubt they changed the airbox.

Install is easy - open box, pull out stock filter, replace with Works, reclose box.

Air filter will NOT void your warranty. Car does feel a bit peppier. I don't have a dyno sheet to show you, though.

Most any axleback will give a performance boost, but all will make the car louder. RRM should be decently quiet since they use a traditional muffler. Most of the ricer options (GReddy, HKS, etc) are just an open canister. They aren't even really mufflers - just resonators shaped like mufflers...

 

the works one is by far the most low profile exhaust available, and I'm almost 99% sure that the drop in will fit. PM Jamie though. I will be getting this exhaust for sure!
