Help me to make my ride faster, plz.

okay as far as perfermance wise...i'm a accord owner but i'm sure i can give ya tips on spending money. A muffler will DO NOTHING TO YOUR CAR. Unless u upgrade your piping from header back u will get minimal to nothing hp/tq. FOr the 100-150 range u could probably get some MSD wires and plugs. U will get a slight better response from your car and (happened to me) better miliage too. I would probably just recommend saving up for like 3 weeks and get a header or something...anything u put on ur car for under 200 bucks will probably do nothing to your car. I had to spend 600 plus 500 labor( DONT ASK) to get my header back setup on my car. It was well worth it cause it brought all the hp's i lost from a clogged cat and a leaking header. As for your suspension. Just look around and u might find a steal from someone else's setup their trying to get rid of. If you dont like ur ride that much go back to stock
