Hey guys/gals. Well, the winter in Chicago has been... interesting to say the least. Although I dumped some cash into getting my winter tires/wheels (good idea btw), I have been able to scrape together a few hundred bucks to get a few upgrades.

Outside of already installing the K&N drop in filter 2 days after getting the car in June, my next upgrade will be the Greddy SP Elite axle-back exhaust system. Any comments on it for the folks that have it? After that, I was thinking some sort of intake tubing... I really want to get rid of the sound generator tubing and the generator itself. It also seems like a new intake system is both pointless/pain in the butt. I'm not going to BS anyone and pretend like I know a lot about performance upgrades but wouldn't those 3 at least improve overall HP a bit? Any CEL's? I have looked at dyno sheets for all 3 and am still trying to make sense of the number gains. Would an inlet hose be worth it? Specifically the Perrin one. I plan to do upgrades slowly and would like to reach at least 230 HP to the wheels when it's all said and done (staying NA). Header, over-pipe and whatever the middle piece is called would be replaced with a larger diameter possibly next year. Tune if necessary (still trying to wrap my head around tuning). Any help/suggestions would be appreciated.
