My experience with exhaust is the most important part is what you do after the muffler. If you end the system  before the rear axle you can expect a lot of resonance in the car/cab. If you take the tail pipes over the axle and turn out behind the rear wheels it is greatly reduced. If you get all the way to the rear bumper you will get little or no rumble in the car/cab.

I have 2 chamber Flow Masters with headers on my Ranchero and they sound great in a parking lot but are very annoying at freeway speed.

I just have a thing about flow masters I think. I have heard so many on Chevys and I just can't stand that hollow/tinny sound. They may not sound like that on a Y. I have 2 1/4" Magnaflows on my '56 and it sounds great (to me). Not loud and all Magnaflows are stainless, a good thing.

I cant send a sound clip because using a computor is difficult enough but  sanderson headers and magnaflows sound great . Good throaty sound and you can still have a normal conversation inside the cab .... until you get on the gas  and that is usually short lived  then back to normal .  pricey , but worth it.

mr.uglyduckling.  Requests for parts belongs in classifieds, not technical.  You’ll also get a better response on your request if you start a new thread rather than attaching it to one that’s already several pages long.  Be sure to state your location for shipping or pickup purposes.

In regards to what you are looking for, I have a stack of manifolds but will not ship.  But on the flip side you’re welcome to pick through the pile and pick out what you need if you’re in the neighborhood.

Vic,

         Don't think so, but I never really sorted it out w/o mufflers. Not a noticeable difference anyway.

So does the ET drop off without the mufflers. I have never ran without the mufflers but I am curious.

The red car runs them also. Pretty much the same as Vic's, 2 1/2" pipes, X crossover etc. Sounds good, some resonance inside at cruise. I don't have the HP Vic does, but the car runs the same mph with the mufflers as it does with open headers.

Thanks Gary for the update about the 400 HP limit, I didn't think I wanted to replace them knowing what I paid for them.

On the youtube Vic Correnti is showing from Charlies clips at the drags the black 56 bird with the white top is mine and it has hushpowers as well, and they do a great job producing the 50s sound. Vic, when I talked with them at flowmaster even though they say up to 400 hp I was told they can go some past the 400 hp max, they are just staying on the conservative side to play it safe.
