Which one is louder????

 

Original 40 is louder. That was my first option until I heard of the Single-Chamber Flowmasters....louder

 

I wonder why Flowmaster's website doesn't say that? You are referring to the 30 series right?

 

The single chambered Flowmasters are called Delta Force, Theyre a totally different muffler than the 30 series

 

fordfan's right. DeltaForce racing flowmasters.

 

10, 30, 40 series... the lower the number the louder right?

 

You are correct

 

cool thanks 95 F150

 

those sound clips sound alright....

 

here is what I got right now, BBK shorties-highflow cat-Ravin z33. I live out here in Cali and I really wanted to knock the Cat out and run straight pipes, but that is probably not going to happen. So..... I want the loudest muffler available w/o knocking out the Cat.

 

I thought Cali was also **** about sound,andyou could only be +/- so much from stock.

 

The Imco's don't sound near as good as Flowmaster's, I ran true dual Imco's with shorty headers, higflow cats and an H-pipe for a couple of months and had the mufflers swapped out for something else. I was very disappointed in the sound.

 

yeah like I said I am out in Cali but my truck has Indiana plates on it.......so MAYBE they might bend the rules a little bit....

 

If the truck was built in indiana the only thing Cali has control over is noise level.

 

well my stupid neighbor backed into my Right Front today, so the muffler is hold for now. I am really leaning towards the Original 40 series. We'll see.....
