finally got my 86 f150(5.0) running jus right. currently im jus runnin strait cats and it sounds "ok" but I really love the sound of the 14" maggies I was thinkin of cuttin off one of the cats and installin a 14" magnaflow but most of my buddies say that on older trucks flowmaster is what should be used. so now im turning to you guys to see what yall think????

any help would be great

 

flowmaster!

 

one of the cats?? isnt there only one

buddy of mine had a 86 f150 5.0 and he had the cat cut off and a cherry bomb 1 chamber put on..sounded NASTY

but that was the only converter i believe..hell its been 3 years

 

Flowmaster 40 and a high flow cat

 

mine has 2 cats. and I really dont want a really "nasty" sound lol but I might jus have it with jus one cat haha....I was thinkin original 40?

 

yea cut just the one and original 40

 

thanks for the help guys....yall wouldnt happen to know the part# on the orig. 40 3" SI/SO

 

you may wanna run a 2.5" in/out..

 

3'' sound TOO big??? I taught that was the best setup for a single exhaust setup?

 

I hate suggesting Flowmaster products, but they do give a great sound on the old pushrod V8s. Go for the original 40.

 

darren sounds like one of my buddies haha!! but thanks for the help!!! so 2.5" or 3" for my setup...one cat, flowmaster orig. 40 and ? size pipe???

 

3" off the Y pipe to a 3" inlet 40, 2.5" tailpipes if dual tailed.

 

ima stay SI/SO....3" all the way it is!

 

do they not use the term "original 40" nowadays??

 

Yes. They killed it after the Super 44's introduction debute in March '07, brought it back in late 2008 from a public demand, called it the Standard 40 for a couple months, and now re-named back to Original 40 Series.

The crap aluminized original 40s part # begins with 4, 43041 is the 3" in/out single muffler with offset inlet, centered outlet, 43034 is the offset inlet/outlet. There is no center/center in 3".

Stainless steel t-409 grade part # begins with an 8 and contains three extra numbers vs the five in the aluminized, the two 3" stainless originals available are #8043041 for offset inlet, centered outlet, and #8043043 for both ends offset. There also is no center/center available for 3".

I would suggest offset inlet centered outlet for reasoning this is the best fitment for trucks.
