Muffler

[strokin&smokin]

The other day I installed my 4" exhaust and when I got to mounting the muffler it said for louder exhaust install the muffler backwards, so of course I did but I was told that doing this hurts you MPG??? Is this true cause it seems that a lot of people run straights and dont complain about their furl economy.

if you want it loud run it strait piped w no mufler... I couldnt tell you about the milage... my guess is that it wouldnt be that hard to flip the mufler around and do individual milage test on them if you use clamps instead of welding the exhaust! my opinion is that you should do a milage check on it now and if its better than it was when it was stock your good to go if its worse then def change it.

Just straight pipe it, you won't regret it!

Would you at all damage the muffler if installed reversed? i have an 05 and am looking at an MBRP....Wish I could go straight but I am in CA

I have been running mine reversed for around a month now and havent seen any real damage as far as I can tell. But who knows.
