one of my cat is rattling, looking at an local for sale ads and wondering if the sedan and coupe share the same catalytic converter?

 

Good question, I know the aftermarket Fast Intentions cats use a slightly smaller ID piping for the sedan, so there could possibly be a difference w/ the OEMs, hopefully someone can confirm, I know they will physically fit since there are several aftermarket Test Pipes & cats that use the same part # for both models.

 

They should fit just fine, part numbers are identical from sedan to coupe.

B08B21ET0B – Right Coupe
B08B31ET0B – Left Coupe

B08B21ET0B - Right Sedan
B08B31ET0B - Left Sedan
