I am so confused on these things.

I have a stage 2 car. With CX racing h/e. Stage 3 pulley. Injen CIA. Ingalls TD.

Other then that its stock, meaning stock catback.


I need to know what header/downpipe is best for this setup, and for ferther modding within the next year.

Also, if I need to replace the cat to get best gains. Help me out with idea's if you can.


Thanks!

How far do you plan on going with the mods?

 

Pretty far. I wanna go TVS sometime in 2010.
Alot more cooling mods.

Do i need an exhaust tho?

 

you dont need one but it would be better to get one and just go 3 in i wish i did now i need a hole in exhaust

 

What ever you get make sure it has 1 3/4 prim, and a 3" collector on it if you plan on pushing big numbers down the road

 

Could you send me a link to one just like your talking about?

What options do I need?

Im sorry, but I know NOTHING about header/downpipe/exhaust.

 

No problem.

If your in a state with emisson's or noise is a big concern get the cat as it will quite it down. If you don't mind the noise and a couple hp get catless.

If you are going to run a wideband the extra 02 sensor bung comes in handy.

If you are putting this to a stock catback it needs a 2.5" exit on it.

If you wanted to do a full 3" exhuast you would get the 3" exit.

 

Okay, got it.

So I want to go with the 3' exit. I have a stock catback right now, but I will install a new catback 3' at the same time as the header/downpipe.


With the 3" I should get more power right?

Ive heard of people losing power, I dont wanna make any mistakes.

and Thank you for your help.

 

Yes,

That is what you would want.

You will not loose power just change where you make peak power.

 

Oh okay. Makes sense.

Since im here, what exhaust is best?

I think I like the vibrant.

Good choice?
