Question Most bang for the buck...

So I've got my 03 Legacy SE wagon, and I really love my car. It's just that, well, I wish it had a bit more umph. I don't need it to be THAT fast, but would like it to be a little faster, without having to spend too much $, and not screw up the warranty. So what's the easiest way to get noticable improvement in horsepower? I have a K&N filter in already, and that helps a small amount. Even sounds better when you get on it a bit. Just wondering what others have done to get most bang for the buck, and not make it too loud....

Let it breathe better.

Start with a cold air intake (if there is one) to complement your K&N. Then save up for an exhaust system.

Best bang for the buck in intakes from what I have read but if you got the cash I would get a Cobb might be a little loud for you

Remove your muffler and replace with a pipe (2.5inch) and chrome 3" tip. Or just take your muffler off.....it's the best mod with no $$ involved plus it increases "peak" hp and torque.

Im pretty sure youactually lose HP witha straightpipe. I had one on my car for 6 months, and it was terribly loud, anyone that heard it can testify to that. I replaced it with a Stromung Muffler (I already hadthe midpipe) andthe performance of the car was quite a bit better.It also sounds a hell of a lot better.

ok well focusing mostly on the quiet part of it, i would recomend dropping weight from the car. Lightened flywheel and pullies. And as far as exhaust and intake goes, these compliment eachther, sodoing both will be the most beneficial. if you put enough resonators in even a custom exhaust you can make it reasonably quiet. And as far as intakes go, I've got the rallitek one, and am very pleased with it. It is only loud at high rpms at WOT. And yes it's a short ram but i feel that it is better than a CAI for a few reasons, hte major one being that at any speed whatsoever, unless you live in the desert, ample cold air is coming into the engine bay.
