It sounds like a jet taking off at full tilt. It makes a high pitched scream.

It's not as loud as I thought it would be, actually quite livable, but sounds goofy.

Anyone else have the screaming noise?

Have you ever heard a Ford 6.0L with a straight pipe? :eek:

Common for a VNT.

only when its warming up. after that sounds pretty good. even better when you put your foot in it

4 inch is simply just too small

My lb7 sounded a bit weird too, i'm not sure what the difference would be between mine and an LLY, but I kinda got tired of the howl. Still not as bad as a 6.0 psd though. ):h I finaly went down to the local shop and got free flowing muffler put on. I'm much happier, sounds more like a big glass pack than a muffler, and i'm thrilled with the deep "tone" it has now. Much more civilized at 70mph too, with the straight pipe I'd get a lot of "drone" noise going that speed. The straight pipe was good for making people cover their ears on the sidewalks though, haha.

J-HEFF

I have 4" duals and Im having that same whitsle/ jet like sound. Thats not what I want. I wanted something like the sound of my dad LB7 stock pipe no muffler. I have a straight thru muffler but no cat. Do you think the sound would change if i took the muffler off?

i want a jet, i want a jet.
i cant to get my 5" exhaust. i am gona try it with out the muffler and with it and maybe even change it to the one max power got.

the jet engine sound. lol i love it

I ehar the 5in str8 piped is a real beast..I can't wait for that..the stocker str8 piped is just tooo quiet for me...even w/ a 5in tip...
