Magnaflow Muffler P/N 14591

Has anyone tried Magnaflows muffler 14591?
It is about the size of the Stock muffler
so I would asume it is really quiet, but of course way better flowing then the stock muffler.

i had a 13746 installed in place of my stock muffler....its not real loud but does sound more like a truck....i also changed the pipe after the muffler to 3'' and added a nice tip.....left all the factory pipe before the muffler as it was...the 13746 is 2 1/2'' in and out so i had to stretch the exit from the magnaflow to make the 3'' work...

hey TonnyG, I have the magnaflow 14591 just installed and so far I love it, definetely much quieter, just enough drone, they are cheaper on ebay but I wanted a warranty (the salt on the roads here in winter kills an exhaust) so I got it here magnaflow 14591, or you can try one of the vendors here, they are always running sales/specials. either way its a great system and very easy to install. keep us updated if you decide to have them... and do post some clips too
