Welcome to GenVibe! As far as mods go, as others said, K&N makes a short ram intake that's awesome (K&N #69-8613TS)! I've had one installed on my 2009 GT since July of 2009 without any issues. I use an AEM Brute Force Dryflow air filter (#21-203BF) and an AEM air filter wrap (#1-4000) with it. I also have the Magnaflow catback exhaust system. It sounds great. It's loud, but not obnoxiously loud. The fit of it was great and I couldn't be happier with it. The only problem is that Magnaflow only makes a direct fit system for the 2009-2010 AWD and GT, not the 1.8L or 2.4L Bases. You should be able to get a custom setup put together by a local exhaust shop for a decent price though. If you decide to buy any Magnaflow products, check out
Hott Exhaust. They have great prices and offer free shipping. Be sure to click on the "Get Coupons" link on their homepage, tell them what product/s you're interested in and they will send you a code to use to save even more money.
You can also use the 2009-2014 Matrix TRD front strut tower brace, lowering springs and rear anti-sway bar on your 2010 Base. Check out
TRD Sparks for great prices on these parts. Be sure to keep us updated on any mods you perform and post some pictures when you get a chance
