Where can I buy the valve

Walmart usually has a couple on the shelf.

The valve solenoids are not going to do you any good on the tips, if the internal tubing of the muffler tip is not designed correctly from the start.

Hence the valve tip side needs to have its tubing go directly through the muffler, and not the flow once around the entire muffler on the standard muffler split tips instead.

Standard split tipped muffler,



NPP muffler , with each tip having a different path through the muffler instead.

No doubt, What I was really referring to is called the NPP vacuum solenoid. I found There are 3 part #s for it Current GM part number: 15782802 @ $69.00. Interchange GM part numbers: 25794609, 25794610.

I have found the 25794609 version @ $43.40. Does anyone know if there is a difference in the part itself? Best I can tell they look the same.

Thanks

Go here, search by year, and should give you the correct part number needed for your year vet.
