What are people using for mufflers on the R1 motor with the Avanti headers?

Thanks, joe

By Avanti headers, are you referring to R3 headers? Muffler choice depends upon how much noise you like to make. Any good 2 1/4" system with a pair of performance mufflers, like Flowmaster, should work fine. Mine create a lot of low frequency harmonics at about 28 to 42 mph in drive, they are very quiet at any other speeds.

From my own experience, Flowmasters will give you a loud, raspy sound that will rattle windows in any neighborhood as you drive through. Magnaflows will give a low burble that opens up as speed and rpm's increase. Both will shake the ground when starting the car.

After having both, I decided I'm not 25 anymore...I prefer the Magnaflows.

I have mufflers from Edelbrock that arent loud but seem to do the job well. Throaty sound but not tiring on the freeway.

I've no experience with Edelbrock mufflers but they sure make some mighty fine performance products. I would expect their mufflers are excellent.

Magnaflows are stainless steel and will last longer than Flowmasters.
Summit Racing has Totally Free Shipping—includes free handling and delivery via standard ground shipping anywhere in the Continental United States on Magnaflow.
My R1 has the Magnaflows.

Thanks to all. I'm more interested in performance (spell that breathing) than sounding like the fast and furious. Sometime in the next year (or so) I want to drop the R1 in a '56 Power Hawk. A little rumble would be OK though. In response to the question on what I mean by headers, I mean the Rams horn style. I like to keep everything but the carb and fuel pump straight Studebaker.

So NOW you are trying to tell us we are not talking about a Studebaker V-8 powered Power Hawk?

Ramhorns are used on small block Chevys.

Anyway the Manifolds have nothing to do with the Mufflers, whatever fits will work.

I'm guessing he's talking about R3 headers......

Rich,unless Chevy made Avanti R1s I would guess the Hawk WILL be Studebaker powered ?

That would be my guess also, but whats with the "Ramhorns"? Stude. Manifolds go down not up.

Here are some R3 exhaust manifolds...

They look very much like Chevy Rams horns to me...

The Chevy Ram's Horn manifold go above the edge of the valve covers. The R3 manifolds do not...while visually they look similar but once installed the differences are obvious.

It will be all studebaker powered, In the dirt track world, where I hang out ( I worship at the alter of speed) we refer to that style of manifold as ram horns, and yes, GM makes a set very similar to the R3 manifod, that's why I used the term. My concern, when asking about the mufflers, is to have the best flowing exhaust from front to back. Good pictures, those are the manifolds I'm interested in.

StudeRich, Sorry I scared you like that, it wasn't intentional. ;>)

My vote is for Hooker Aero Chamber mufflers.....if you want the best flow.
