well im ordering a magnaflow catback exhaust system for my 08 scion tc and the only thing available under the site is for a 04-05 scion tc...and l dont believe there are many differences in the models...idk...should l call the dealership?

It should fit.. the models have not really changed it. They've only done changes to like the taillights and headlights so you should not have a problem. Good choice on the magnaflow =) HKS is another good brand as well.

l would call just to make sure, ask if the exhaust systems are the same from the 05 models to the 08 models.

It will fit as will the Borla muffler which gives better airflow then catback.

Should fit.
