howdy yall!!!! i have a 4.6 f-150 98 and i was wanting the loudest and deepest that are street legial. if yall have any suggestions will yall please let me know?
would it be louder to go straight out the back or at a angle?

 

Welcome Kuntryboy24 ! Well, straight pipes with no mufflers are the loudest; illegal in most places. Flowmaster 40s (non-delta flow) and Dynomax Ultra flows are loud. The Ravins can best be explained by others (no personal experience here). Good luck !

flowmaster has the loudest. check out their web site and stay away from the delta flows if you want loud.

yeah, flows are loud, but if you have an 01 like me, the four cats just make it a lot quieter.....I just had a ravin installed on one side and a fm 40 on the other.,........after hearing both on the truck I went with the fm 40....yeah the flow numbers aren't as good, but hell the difference in the two was not enough to make a discernable difference in power,,,,,there are many more limiting factors in the exhaust than just the flow of the muffler,,,,my ears said fm 40 and so I went with the custom cat back fm 40(3" in dual 2 1/2" out)....no regrets and no ravin for me

 

Meskin, sorry, but I'm happy to hear that I'm not the only one who's FM 40 isn't loud enough. Check my sig. It's just not loud enough. Is their anything we cna do to get em' really roarin'?

go right out the back with straight pipes...not too loud, the 4 cats cut the sound tremendously...try it and see, just leave yourself enough room before the new y-pipe to add a muffler if you choose...most places around here told me to run it straight, and then if i didn't like it they would stick a muffler on, no labor...i just had to buy the muffler...ask and see, couldn't hurt..good luck, Rich
