I recently bought an '09 Lancer GTS automatic and I'm wanting to modify it. I bought the Magnaflow catback exhaust system today and wanted to know what else would be good for an auto. I'm still really new at this, but I'm eager to learn what will and will not work well. If anyone can help me out and tell me which intake, if any, would be a good addition to my car and whatever else will improve the engine, I would certainly appreciate it!

 

Depends if you want a full cold air intake or a short ram, for a cold air intake I had an injen for my 2010 gts auto and it was great for higher rpms and had a great sound. For short ram I would either go with a k&n or a takeda, both are great companies and both get involved if your dealership brings up any problems with your warranty. Short rams are great for low rpms and gives a little more torque and pick-up, and are great if you have the chance to pick up a ralliart/evo hood.

 

Would it benefit to do that or just a high quality drop in air filter? I put a Magnaflow catback on it and it sounds good but I want it to sound like a little menace from all angles.
