The super 10s are quieter, I know that. The delta is a race series.

Are the delta the bullet looking mufflers? It's been a while since I looked into the FM mufflers.

The only differences I could find besides price is the Super 10 is available in inlet/outlet sizes from 2.25" to 3". The Delta Force 10 is available in inlet/outlet sizes from 2.5" to 4".

Okay I just got off the phone with FM tech, I was told "there's no sound or flow difference between the two".

That's what I thought. I know the outside casing is different; the FM10's look more like a traditional muffler, while the Delta Foce 10's are bullet shaped.

Those are the ones I'm familiar with, but there is also a bullet looking muffler from FM.

Here is the one I was talking about:

The "Delta" series are offered in all the traditional cased mufflers.. It means they have 2-3 more sound wedges in them to cut down on the interior noise & are generally more expensive than the regular/super series line.. The "Super" series don't have these extra wedges.
