I have a 03 F150 4wd supercab with the 5.4. I want to put on a better system but something that is not to loud just flows better. I was thinking about a single outlet large diameter system in the stock location (it all appears to be choked by one cat convertor anway). What would be the best system to install, Mag Flow, Gibson, Flow Master, Etc. Thanks for the help!

 

I installed a single in 2 out Flowmaster 50 series on my 05 with 4inch S.S. tips it sounds great but idles and interior resonance is zilch!

Welcome ! Did you crawl under the truck to evaluate this? You might want to take another look. What you detailed sounds like a good plan. I would suggest a stainless steel, straight-through design, pre-engineered cat-back kit.

 

Sounds like I must have missed something. I'll check it out Thanks

 

I have recently installed the magnaflow 15609 I bought from Troyer Performance (best price around). It has a nice growl when you step on it but not so loud that you'll want to take it off because it's annoying. I've heard the flowmasters and they are fairly loud. There have been many postings regarding the types of cat back systems so you may want to search for them.

 

if u want a cheap alternative cut the stock muffler in half... gut it then weld it back together. seen some people do that actually sounds nice.. kinda makes it a giant reconator and u can cut it and gut it urself then just have a muffler shop weld it back together for you

 

hummm...

where's that Cooter pic at?

 

hey i didnt do it... but this is texas and we do have our share of rednecks

 

hahaha

 

Shove a 2&1/2" pipe through a 3" straight-through muffler and weld em together.

 

lol, that's the one.

 

MT offers a substantial discount for calling and being a member here right? if not, that is not the cheapest price i have seen for a #15609 magnaflow catback...
