I own a 2003 mazdaspeed protege and i was wondering if anyone could tell me what the best brand of exhaust systems are for a turbo-back.

 

There are several vendors, from GHL, Corksport, Megan, and so on. A lot is to do with preference.

I am not gonna say you must buy from this vendor, but I do represent the company (handle questions, suggest products) on another site. Street Unit sells some pretty good exhaust systems. Cullen runs the shop, and has been a wealth of knowledge in helping me with his car.

Check out www.streetunit.com for more options.
