its not really worth it to just add tons of little things... you'll be spending a pretty penny on crap that if you are lucky may add an inconsequential 10 hp to your ride. Save up for something big if you go this route. Adding exhaust and bolt ons to your honda may make it half a second faster to 60...... but its still gonna take like 9 seconds to get there cause the stock engine is so weak in the first place.... in my opinion, its a total waste of money. If anything, work on suspension (wheels, tires, springs, struts, etc). This will be where you get your most noticiable performance boosts.
