What size magnaflow should i put on a reg cab f150 i plan on dumping them any suggestions

 

anyone

 

What size engine? That is all that matters in what size muffler. In general, the smaller the canister, the louder. Are you going with two mufflers? DIDO? SIDO? SISO?

 

its a 4.6 I wanted to split up the pipes and run two mufflers dumped.

 

I am not sure about the pipe size, a call to Mike Troyer, he should be able to tell you that one.

As for running 2 mufflers, are you looking at removing the stock Y pipe, and putting in a X pipe, and 2 SI/SO mufflers ?

Or is this a case of you want to have 2 pipes exiting, and would have a SI/DO muffler ?

I have not seen a install of leaving the stock Y pipe, adding another Y pipe back to 2 SI/SO mufflers yet, kind of a waste of money to do that. Not much to be gained by going stock Y to 2 SI/SO mufflers, and it might be quiter then stock if you did that.

Another question is what does true duals, do to the 4.6L engine. I know what it does to a 5.4, but I don't know how well the 4.6L takes to true duals. Again a call to Mike Troyer and he would be able to let you know if it is a good idea to true dual a 4.6L.

 

SIDO is probably all you want and keep the stock y-pipe. 2.5" in and dual 2.25" out.

 

Hell no im not leaving the Y pipe its getting cut so i will have two seperate pipes. so witch size muffler do yall prefer
