hmmm..maybe its just cause its not too loud in the cab.. never heard someone else drive the truck.. and why do you think it would be custom? hmmm i think im gunna go get under the truck





"Did he ever say what series flow it is? Flowmaster makes a pretty wide ranger of mufflers."

NO, i didnt, not sure what series it is... the muffler should say, correcT?

 

I doubt the muffler will say it on it. I'm pretty sure flowmaster doesn't make a cat-back for the F-150 so it probably is custom.

 

they actually do make a cat-back for the F-150's.

 

Ah, must have missed that when I was looking. I'm not a fan of flowmaster so its not surprising lol.

 

i love how the flows sound but i want something a bit more mellow for my F-150.

 

Yeah thats exactly how I was. I liked it on the Ranger but I don't need anything that loud anymore.

 

Yeah the muffler won't say. Just measure it. The bigger it is the higher the series and the quieter it will be. The flow 40 is what most go with and I think its about a foot long.

 

hmm maybe im just going def... lol

 

the 5.4L is kinda mellow, I mean it will be unless you go full out. I wanted mellow 5.4L sound on the F150, but my Ranger will sound like a rapped 5.4L. :)

 

dude its pretty simple if you want louder... cut that muffler off and put some pipe in its place and there you have it... thats what i'm rolling with and its loud as $hit... actually too loud in my opinion lol

 

its not always the muffler. replace the cats with something else if you want it to be louder. that is my vote. it will make the most difference over muffler choice.

 

damn this thread went to total opposite direction

 

Well looks like some high flow cats will be next on the list! thanks zach

hahaha i know! and i was not expecting 80+ replies either haha
