If any of you are interested at seeing the inside of the stock ISF mufflers - Here they are.

Note, these mufflers were modified with dual inlets, but otherwise they are stock.

Nice. Different views than JoeZ or someone that shared their findings in years past. I always appreciate a first hand look at well executed engineering. Thanks for sharing.

 

very nice. do you know the story on the dual inlets? why it was done?

 

^^^^That muffler was my old muffler cut from my old modified dual system. It was done to see if it would produce any power and change the sound. The answer was yes to both, but the changes were very minor. See picts of my old system.

Thanks for posting. Cool to see the design in the flesh.

 

Ok I see. Thanks Lou. I was
Curious about using the same
Idea as you did. But making the
Added inlet a straight pipe
Through the muffler and putting a valve on the backside of the muffler (on the added inlet).

 

what did you swap this set up for? and what is the differenced between the two of them??
