Hello everyone,

I just wanted to get a few opinions on a possible exhaust change. Right now I have a 14" Magnaflow in lieu of the stock muffler on an otherwise stock exhaust. I am considering replacing it with a new SIDO Magnaflow system. My question is whether there would be any measureable improvement in either performance or mileage with such a change. For the record, my truck is a 2001 4x4 with a 5.4L. Thanks for your input!

 

Hello LLM07,

if you switch to a different magnaflow muffler i dont see any change in performance or milage, just sound different,

 

Swapping to a dual outlet muffler would sound better and perform just the same as it does now.

 

Thanks, it sounds like I would be spending money just to get a different sound. I think I will look at another mod instead of exhaust. Thanks again!

 

No problem. Good luck with your plans.
