I'm interested in buying a high-flow cat with my existing apexi world sport 2 exhaust. I am using the stock cat and the piping for the exhaust up to the cat is 60mm (2.36 inches) and I'm wondering what size high-flow cat I would need. I've seen 2.25-2.50 but will that work for my setup?
Which one of these would I need? http://www.kteller.com/store/index.php/cPath/23_25

 

bump

 

I dont have any info to help you out but I am getting a WS2 for my EJ8 as well and was wondering about this same question so bump for you.

PS. where in PA you from?

 

It doesn't really matter, you will need to weld on a donut flange and the 3-bolt flange regardless of what size you buy. I would go with 2.5" though

 

i also want to get a high-flow cat, but i was wondering if there are any problems with smogging with them?

 

wow kteller prices are expensive
you can get the same cat on ebay for 55 bucks shipped
carsound hi flow

 

I heard those high flow cat's are useless your better off just gutting your stock cat.

 

if you weren't worried about emissions, you could get a test pipe. I got one, but I'm lucky enough that my state doesnt have emission testing.

 

just get a 2.5" test pipe , or a spun bodied high flow cat from smsp.

I think I'll just run a test pipe but I don't want it to sound like **** just a little louder you know?
