I have searched & can't seem to find what I'm looking for..even though I know they someone makes them bc they are used on various downpipes, test pipes..here's what I kind of resonator I am looking for...

2.5" in/out
4" diameter
8" or 10" length

Any direction would greatly be appreciated....

 

Check vibrant performance. You also might look at race mufflers from flowmaster or magnaflow.

 

^ Yup, Vibrant has some.

 

tried them, the shortest they have is 12"

 

Just found this, and it should work for what i am wanting to do....
