Bolt-ons

Hi, I'm new to this forum but not new to Integras! I just bought a 98 Integra LS 5spd to replace my 91 Integra LS. So far I'm loving it, the only complaint I have was that I was told the 98 LS has VTEC but as you probably know they don't. So I'm looking to add a few Bolt-ons to make up some extra horse power. I'm not too into major modifications so I'll probably just stick to Intake, exhaust etc..

I just wanted to know if anyone has any suggestions for me, like brands and models that will benefit me the most. First hand experience would be great. My budget is pretty open but cheaper is always better. Thanks!
