I currently have an "05 F150 Lariat SCREW with a single exhaust running back straight from my cats, which then splits in two to make the straight back duals. I'm thinking about adding a magnaflow to my set up, but I don't know what this will do for me. I'm looking to keep that sweet rumble and still have maximum torque and horsepower.

Any suggestions?

 

get one 11" maggie, si/do keeps your performance up better than a si/do or true duals without a tune,

and you will have a nice rumble, now it wont be loud as straights, but itll still be good

 

14" Body SI/DO

 

fine then

 

Remember, their isn't an 11" SI/DO, and he wants dual exits

 

lol yea i remember, but i guess i didnt read that part, all i read was he wanted to keep his max tq and hp

 

would it be better to run to seperate pipes all together with two seperate mufflers?

 

Thats true duals, and no, it would be a mistake if your torque and performance numbers matter to you, unless you have some serious engine mods like LTs and a supercharger true duals isn't very necessary. Stay with a single in, dual outlet system.

 

awesome...I appreciate the help
