i have a greddy evo, and i plan on getting a jdm itr 4-1 header and a 2.5" carsound high-flow cat. i know the header will bolt up to my block, and the high-flow cat should bolt up to the header (correct?), but will the evo bolt up to the 2.5" cat? has anybody done this?

 

as long as u get the right inlet/outlet sizes, everything should be cool

 

what do you mean by inlet/outlet sizes? the header collector is 2.5", the cat will be 2.5", and the exhaust is ~2.36", if that's what you are talking about (if not, i have no idea what it is you are talking about). im asking the question of whether or not these will all fit together without modifications to anything, because i heard that you might need to modify some part of the exhaust/cat to fit onto the jdm itr header, but i dont know if i would need to with the parts i plan on getting.

 

well the outlet size(for the cat) has to match your inlet size for the exhaust.

 

Here is your answer...

<U>YES</U>

I have the exact same setup. A JDM ITR Header with a 2.5" IN/OUT Carsound cat and a Greddy EVO WILL bolt up PERFECTLY without ANY mondification.

 

better question.... will this pass smog in california? wat do ya think aaron?

If you got the hook up, it will!

 

haha... not exactly the response i was lookin for... but on that note, the best i heard recently was $100 to 150 to get me the "hookup"

 

i dont know if it will pass...

im gonna need the "hookup" in about a year or so

perfect. just the answer i was looking for. thanks . how do you like the setup, silverb18c1?

 

are u goin to be using this for any performance reasons? if so u should seriously think about getting custom 2.5 inch piping after cat. it's not goin to give u alot of power if u let it run freely in the header and cat then squish it back down through the exaust

 

yeah, going from 2.5" to the cat, then 60mm to the catback is going to be backpressure city.
