I searched and couldn't find a answer


I need to get a cat or a test pipe to finish up my swap in my crx. I want to get a carsound cat but I don't want to go to the a muffler shop because of the crazy *** prices around my area. Its looking like it going to be 300 for the cat and install.

So with that said I'm looking at the omni test pipe for the time being. I know that the us version is 2'' and that is the size of the collector on my header. I have a rsr exhaust that is 60 mm which is 2.364 inches.

Will the u.s omni test pipe fit directly to a rsr exhaust ?
