well my b-day is tomorrow and i think my gf got me some mufflers for my completely bone stock mustang. She kept askin me what i wanted and i just said stuff for my car, so my friend helped her out to get somethin. I'm thinkin its gonna be flowmasters, but idk. How much will i be lookin to get these put on proffessionally?

 

Well the mufflers are around $75 each depending on the ones you buy.If you plan on just changing mufflers and the tailpipes it can get some what pricey..............good luck and Happy Birthday!!!

 

I believe they will run you about $100 each. That is if they shop buys them. This was with flowmaster two chamber mufflers. Hope this helps some.
