I just got a b16a put in my ek and I have the cat and jdm itr header just hang there(really loud for daily driving) What kind of high flow cat should I get and what will have the least modifying? I believe length is 17" Correct me if I am wrong.

 

yes you will need a 17in length cat, and get a carsound cat customized w. flanges to fit the JDM header. a few people on here are selling them and places make them ask around

 

the new Type 1 cat is made with the right jdm flange and the right usdm length, you should think about that, it looks sweet on my bros EG, sounds good too

 

i picked up my cat from IPS racing. good guy.. good service.

i believe he's also on honda-tech as "Mike M". hit him up with a PM.

 

a cat to except a 2.5" collector is 10 bucks less then the 2.25". . how bout that I guess?? I wish I would have saw that before my cat **** on me..

 

sweet thanks for the info guys.
