Exhaust Sound

[Tommy11421]

Ok I've seen a bunch of guys with 4" and 5" exhaust with either 5" or 6" tips. Some of them still have that baffled sound you get with a stock straight pipe while others have an exhaust that sounds like a jet engine. What causes either sound?

thats a good question. thats the sound im after too. nothing wrong with sounding like a jet! hopefully someone will know what it takes to get it.

Not sure of the specific thermodynamic reason as to why one sounds like a jet and the other baffled.

However a 4" system straight piped or with a muffler is usually more tame then a 5" system.

Is there a specific sound you're looking for?

ive heard several 7.3l's at idle that sound like a jet at idle. would like to know about what set up it takes to get it.

ive got a gotted cat and mbrp 4" turbo back with muffler, and ive had people who know nothing about trucks say "man that thing sounds like a jet"

Straight piping usually sounds like a jet, you have a muffler on it, you have that "products" sound...

So would you get a real loud, deep sound with a 5" straight pipe exhaust that gives off that jet sound?
