I was just wondering if anyone who installed a MF 15609 on a 5.4 has anything to say about it. Does it make a real difference in HP and torque? Did anyone put one on a 4x4? If so how do you like it? Is it worth the money?

Thanks

 

had it on for 5k miles- VERY PLEASED WITH it- would do oer again in a heartbeat- has gotten a little deeper=definte performance increase,got it =from www.fulline exhaust .com for 268 -304 shipped- i know they have raised the price but is still cheaper than anyone else-phil

 

Very happy with it and would do it again. Simple garage install. Doesn't drone like the Bassani did and has a very nice sound to it. Went to my dad's for Xmas and now he wants one for his truck! Didn't notice any power gains, but didn't really expect to on a 4x4 Screw. Didn't loose any power though, which is a problem with some exhaust mods on these engines. Got it from Troyer Performance who is a sponser here on F150online, got it in three days.
