I was surfing random sites looking for a highflow car since I dont want to run a test pipe and choke more than I do in CA and get a 3K fine. I came across this race spec cat on RMR site anyboy use it and does it stink like ****? It looks real small is the car gona still backfire fire like a test pipe since the honey comb is so small.

Anyfeedback would be great
Thanks
chris

here is what it looks like and what is said on the site
Evolution 8 High Flow Catalytic
Normally a catalytic converter is not on our list of racing products to develop. But due to recent SCCA regulation changes; all cars must have a working catalytic converter. That is why we created the RMR High Flow Catalytic Converter. The monolith-type converter used has the highest flow rate of any converter. It’s the closest thing to having a straight pipe. It conforms to all SCCA, EPA and Group N regulations. Includes all gaskets and hardware

 

nobody has any info on this or know anybody running it?

 

here another question about RMR products , does the cat tapper to 2.5 ' , since the down pipe which is 3' tappers to 2.5 to work with the stock cat . Im sure that in order to bolt on to that it must tapper to 2.5'
im looking for something that is 3' all the way ..

 

i guess im better of calling RMR to find out ...

 

calling always works out!

maybe post there response in order to help people in the future

 

Yes, please reply when you find out more info on the cat. I'm interested in purchasing a high flow one...

 

i called today and the gains on the highflow cat over stock is around 5whp. Also it works with there turbo back system which is a 3' all the way throught . Which they have seen some nice gains .
Theres not much benefit from running this highflow cat.
