Lets see how should I start off…. humm I drive a 03 2.5 rs auto tranny >.<. Im trying to look for any way to boost my engine power ^_^ I don’t wont to install anything that will harm the engine in long term use. I want to get a new exhaust system for my car but I dunno which one to get there are way too many out there.

Many people at Subarureview.com recommended the A'PEX Integration N1 Titanium Muffler. There is also the APEXi N1 Exhaust 98-01 Impreza RS 2.5 at

lookie here

but not sure if it works for a 03 model. It should im guessing. Humm are catbacks good for N/A cars? I know that Blitz and HKS offer some. I just wanna know whats the difference between catbacks and other non catback ones.

Now lets say I do install one of these exhausts on my car, do I need to get new headers also or anything else to get the full potential out of the exhaust?

I also checked out the cobb tuning website. I really like their Performance packages that comes with Cold Air Intake System and the Stainless Steel Performance Cat-Back Exhaust System. I trust their products because they have tested them out and they’re a company for Subarus. However I live in Southern Cali and there is no cobb dealer anywhere near me. I know you can order parts online and have them shipped here but who will install them for me? I’m not really sure if other places will know how to install them.

I’m looking for an exhaust that is quite nothing loud that will attract attention such as cops :X

weEe or is there anything that you guys could recommend
