Just wondering if anyone here has ever just swapped the oem Cat with a Hiflow on a Oem Itr set ??

 

I'm sure it's been done at least once.

 

Why would you do such a thing?!?!?

by "OEM itr set" I assume you mean stock type R header back exhaust?

I didn't do exactly that but I did add just a Spoon header and High Flow cat and kept the OEM catback for almost 2 years.

What exactly would you like to know?

 

I don't see the point unless you're going with a larger diameter header.

 

Well, the OEM cat is quite restrictive, so even on an otherwise stock setup, swapping to a high-flow cat would yield some gains.

However, you'd obviously have much better results if you upgraded the header at the same time.

 

well my plan was to swich the cat since it is a bottleneck but I wanted to keep 2" incase i wanted to switch things back later on.I'm also changing to a Edel brock header

Hopefully everything turns out well.

 

I upgraded the whole exhaust system. I have the JDM ITR Header, with a 2.5" High flow Cat and a 2.5" cat back. System seems to work fine.

 

Juice wouldn't be worth the squeeze. Is ruining our ozone layer really worth a whopping 5hp to you?

the cat isn't really a bottleneck unless you have other work done on your car...from the sound of it I would leave everything along if I were you.

5hp? Nahh maybe .5 on an otherwise stock setup maybe not even that.

And a HF cat will pass emissions, not to worry the tree huggers.

 

hey is JDM cat as restrictive as usdm cat?
