Need Input on Dynomax Performance Exhaust system

I am think about putting a dynomax exhaust system on my 01 blazer.  Anybody have one or know anything about dynomax, the good, bad, and ugly please let me know. 
 
 
Thanks

its a pretty good sustem. i have it on my 95 jimmy. its a little louder then stock. if you want like a flowmaster sound this system doesnt have it. but its easy to put on and it does get a bit louder the longer you have it. it needs a break in period.
