Like title says, I've searched and all that but theres so many confusion on for example... jdm header w/ usdm exhaust etc. I have a 98 Integra GS w/ a header that is the JDM's length and the Tanabe Hyper Medallion exhaust, how long does the cat?!?

 

if you are using a jdm header with the usdm catback .. i remember my cat being around 12 inches ...if you buy one of the short magnaflow high flow cats, buy one of the shorter ones.. i think 11.8 inches and since you need to weld on flanges, it should be good

 

my bro had a Omni test pipe before, and i remember those didnt adjust that short, am i gonna have to cut it if i buy one?

 

bump

 

no one else?
