Magnaflow Muffler model number?
Hi,

After reading on this site, I have decided to go with Dual Magnaflow SI/SO mufflers, as well as replacing all 4 cats with 2 high flows. All this with 2.25" pipe. I believe this to one of the best configurations for performance without headers. Although, I am only basing this off of what I am reading here, and have not actually seen a dyno difference. This is for a 99 F-150 5.4. I believe I want the 11", which hopefully will not drone too bad. What model of muffler would this be as I see quite a few on Magnaflow's website?


Thanks!

You could also order it from Performance Peddler for $60.23 -- that includes free shipping as well. Use the code "clubgp" when you check out......

it shouldnt be an issue. Darren has his offset offset, but im pretty damn sure center offset will fit.

Wrongo! its offset centered like the 2.25" version you showed

The 11s dont drone that bad, only at acceleration, only time they're annoying.

Either way it wont matter, offsets have no tone effect what so ever so OP it doesn't matter, only eases fitment for installment.

what exactly do you mean, the muffler inlet/outlet locations? or pipe size? the inlet/outelts locations dont matter, just try to your best judgement have it mount where it would fit best. Usually offset in centered out is perfect for trucks getting true duals.

2.25" piping for true duals will perform well.
