Is the intake/header/exhaust upgrade combo worth it? What is the stock piping size of my car? Do i still need to make the piping bigger if I get the intake/header/exhaust? Considering my exhaust will just be an axle back. TIA

 

anybody?

 

Is your car a V6 or 4 cyl?

 

does the 03 have the f23 or k24?

2.25 or 2.5 piping is good for a catback system. most of the new catbacks are 2.5. yes its a good way to go. there is a lot of power to unleash with the right combo.

if the car has the k24 kpro would also be a good way to go to tune the car

 

The '03 has the k24.

 

Its a 4 cylinder. My LX has the K24. I'm buying the vibrant exhaust flat black too (similar to the ES oval). should i go 2.25 or 2.5?

 

?

 

well with other mods the 2.5 will be better (imo).

 

2.5 exhaust, Apexi WS2 and greddy evo2 are good options...

intake for 03, AEM or Injen or Fujita are good for intake... CAI SRI or v2

headers, the only thing that will work are DC 4-2-1 ceramic or stainless, there is honestly no difference between the two, performance wise, one just costs 200 bucks more and is more durable

 

thanks for the input guys

 

Do a cat-back. An axle-back won't help much.

 

anybody know the stock piping size on my accord? should i go bigger?

 

The stock piping on a 4cyl LX sedan is approx. 1.75"

and yeah I meant cat-back not axle-back
