HG and Exhaust whistle

[speyrod]

I'm curious has there been any discussion to exhaust whistle and blown HG's? Just curious if the slight imbalance of exhaust gases every revolution could create the whistle? For those who have blown their HG did you have the whistle?

Escaping gases via the HG would be so minimal it would be tough to detect at the exhaust valve as it left the cylinder. Then the exhaust of 3 cylinders are mixed in each manifold/pipe, then collected into a single pipe. At that point, there'd assuredly be no way an imbalance would manifest itself. In theory, yes but in practical application, no.

Informationally, both mine did it before HG replacement, and both still do it.

whistle goes away when the muffler is replaced, that tells me the muffler is the source of the whistle.

RT,

New stock muffler?

Not to argue but from stock to one type of magnaflow to another type of magnaflow and I had the whistle the whole time. I think the resonator eliminates the whistle and the engine & exhaust in general produce it. HTH

Doug, I still have my original muffler and the whistle, have read here IIRC at least twice where replacing the muffler got rid of the whistle, I don’t know of anyone who has replaced the muffler with a new factory unit.

TC, Turbo charged 80’s don’t count ;p
