i have a 2004 f-150 fx4 and im wanting to put dual rear exit exaust on it and im wanting something that sounds good any ideas

 

Depends on your definition of 'sounds good'. The majority here enjoy the smooth sound of Magnaflows, with a sprinkle of the noisier FlowMasters around, and a few folks with the throaty Borla setups.

The search button is your friend.

 

Does anyone out there have the Gibson exhaust? Would you recommend it over flowmaster or borla?

 

I just got a flowmaster 40 series with 4 inch tailpipes installed today. Oh, goodness does it sound awesome?! I couldn't stop driving it after I got it installed. Feels and sounds very clean. It is loud though, so if you prefer the quietness of your 150, I would think about getting something else.

 

I have the gibson supertruck and i love it. It exits before the rear wheels and gives off a tight, yet deep and loud sound. Its the loudest Gibson makes. I'm changing my exhaust though to true duals with Twisters because im crazy and i need it to be super loud. but thats just me, i think it's loud enough for 96% of the people here.

 

spintech makes a true dual x-piped exit before rear tire that is louder than anything youve ever heard!
