I am debating on which mod to get next. Which do you guys think would be the best one?

Stillen High Flow cats
Stillen Test pipes
DC Sport Headers (ceramic)
Proflow Design Throttle Body (72mm)

 

anyone gonna write something lol?

 

What do you want the mod to ultimately do?

 

give me power?? lol, I want to know which mod, with my current set-up, will yeild the best results (my set-up is in the sig, its not much).

Maybe I should have said that before. lol

 

MotorDyne 5/16 spacer + MREV2 will give you a better HP gain than test pipes/HFC's and cost less to install then headers. So i would go with MD 5/16 spacer + MREV2

 

I wasnt really looking at those mods right now, I dont know what they will do to the warrenty, I know that headers and back wont do anything to warrenty. I guess I just going to go with the headers for now. and Im getting Stock diameter pulleys soon.

 

The MERV2 is only if you have 6MT... but +1 go with the Spacer... also some Fast Intentions High Flow Cats... better Quality cats

 

The MREV2 + spacer is barely even noticeable unless you KNOW you're looking for it. But you're 5AT (assuming cuz of i-key) so if you were to pick that i would just go with the 5/16 spacer. From your list though I would pick the HFCs because I dont like the rasp of TPs. But its your choice, so G/L

 

well I rooted out the test pipes because florida emissions might come back .

so which one, DC sport headers or HFCs?

(thanks for the input btw!)

 

Headers

 

Fast Intentions High Flow Cats

 

If i'm not mistaken header install cost $800... not worth it IMO

But if you go HFC's get Fast Intentions High Flow Cats, you can't go wrong!

 

Get FI highflow cats, and a 5/16th spacer.

 

HFC's from your list but I'd do the MD spacer first.

 

I have a set of Stillen ceramic headers that I'm not using any more...
