I'm trying to replace my cracked Exhaust Manifold on my 2000 Acura Integra GS-R. I'm trying to keep the costs down since this car has 174k miles on it. I'm only looking to keep it work for another 3 yrs or so, so I'm not trying to put anything really expensive or for performance. I just want to make sure the part fits. I wanted to see if anyone had any suggestions. These are the ones I"m looking at from ebay.

Any recommendations/suggestions would be greatly appreciated. Thanks.

P.S. This is my first post, so if I screwed up something, I apologize in advance.

The 94-99 GSR's have a shorter manifold and cat, you'll need a set specifically for 00-01 models. I'm not sure why that second set crosses model years unless they delete the cat or they are just mislabled...

Ok,

So I ordered the following.

But the connection from the header to the catalytic converter is a 2.5 inch pipe. The hole on the catalytic convert is tapered to about 2". I'm trying to figure out how to make this fit.

I was thinking about this part.

The Bosal or Ischino part.

Any ideas if this will work ? Any help will be really appreciated. Thanks.

same header i have but mines black. i used a magnaflo high flow cat with 2.5 in/out was about 80 dollars at autozone but i have 2.5inch exhaust piping. i dont know if that flex gasket will work your better off getting an oem exhaust manifold from a junk yard if you wish to keep your smaller size pipe for now
