hi, i own a 2002 4dr honda civic LX with automatic transmission. i was wondering what would be the best exaust system to put on it for power gain. i also need to know what would be the best cold air intake to put on it and how much these both cost and how much HP they will add. and yes i know this car wont be really fast and no i cant get another one.
any advice helps thanks-

 

automatic and 4dr, there's two negatives against you. please try again.

 

If you would search, you would find all these answers.

But, I suppose I'll help you out with this one. If you were to buy an intake setup (regardless of what type), headers (also regardless of type), and a full exhaust setup including a higherflow catalytic converter (once again, it's regardless of type) you MAY see 5whp. That's the downside of owning the D17. Bolt-on's don't work well with it.

 

yet another oxymoron

 

Just get a nice RSX-S exhaust and call it a day, i think im gunna try to trade my Royal Magenta Apexi N1 for one.

 

those are nice, that and the rsr exmag
