No...because Flowmaster farms out their production to about 10 different manufacturers, the BS about Flowmaster making all of their own mufflers is a bunch of crap advertising

 

I bought i fake flow because it was so damn cheep, but i knew what i was getting . They told me it was made in mexico and the only diffrence was it had no stamp . They also said they could only get the single in duel out 40 this way . Yes i do plan on getting an upgrade later when i get some more $.

 

According to flowmaster.com under their FAQ page ALL flowmaster mufflers will have flowmaster stamped onto them or it is a fake. It's only on one side so be sure to check both sides. Feel or take a pic of the top.

 

Yep, and Ive owned several. Sounds like your buddy got a fake, and the shop is trying to maximize profit.

 

You have proof of this claim?

 

this thread is from 2006. let it die

besides, this is a LS based performance website. not many of us are running flows.
