I've been thinking about changing my exhaust. I been thinking about putting flowmaster 10 series on. Then I found some muffles called flowsound and they are about $40 cheaper. Some people say they are just as good as flowmasters. I was wondering if anyone has ever had them or know someone that has and what your opinion is on them.

 

Never get a knock-off when it comes to auto parts. Just because it's cheaper doesn't mean the qauality stays the same. Also, I'd stick with 40s series (or some derivative). 10s would be kind of a waste and are made for racing classes that require a muffler for the sake of having a restriction and not for the sake of sound management.
