I currently have Magnaflow dual exhaust coming out of the back of the back of my 05 4.6l f150. i was wanting to know if the flowmaster dumped exhaust is louder? will i get any more preformance? which flowmaster product should i buy? i do want it to be legal for the state of texas.
thanks

you will get more performance from you current exhaust but if you did a dual super 44 dumped that would definately be louder than your magnaflows

 

You'll get better performance from a Magnaflow. Why not just go with a smaller Mag?

 

i think it would be most cost effective if you cut off your tips right now and kept your existing muffler, will be plenty loud for you and you dont gotta waste money on a new muffler

 

very true, cut the pipe off right at the outlet of the muffler and you'll have plenty of sound.

 

is this legal? will pass inspection?
thanks

yes its legal and will pass inspection i have a SI/SO flowmaster super 40, i had the pipe ran to the rear and you couldnt tell i had an exhaust, i cutoff the pipe at the outlet of the muffler and it sounds amazing, one friend said it was louder than his dual 40's, you get the idea, cheapest way to do it, you will love it i promise

 

It'll sound "okay" but you'll lose performance. If you want something is going to sound good and give you some performance, get a Magnaflow Magnapack. Summit Racing and JEGs both carry them.
