I have a 94 f150 302 with 120,000. I plan to install true dual hedman headers with mangaflow exhaust no cats. I was just wondering how much gain I can expect outta this install.

 

better be longtubes if you want gains! and im not sure how magnaflows sound on an old 5.0, much less without cats. go for it!

 

Long tubes for sure, I'd try it with the cats first or high flows. If it's not loud enough, then cut out the cats.

 

x2, then you can change it and not be stuck stuck with something too loud or raspy

 

should be a pretty gain. and definately beast!

 

the headers are long tubes 2.25. I picked em up from a buddy for $50. Still gotta get the mufflers though. You guys think this will be really loud? I dont want it to be painfully obvious that im running it without cats. What size mufflers you think I should use?

 

LTs and no cats will be loud as s**t, I would hate to hear it for the sake of my ear drums, but different people have different noise tolerances. I can say for sure you will get the attention of onlookers.

And if your going with 2.25" true duals, you should obviously go with 2.25" mufflers.. What kind of mufflers? Round body Magnaflows, 2 chamber Flowmasters/Thrushs, Dynomax Ultra Flows, Borla ProXSs

 

5.0 motor loves LTs, no cats and flowmasters period!

Caution- will make some serious noise...
