Summit Mufflers--straight through design?
I have a 406 engine thats going in an 80 coupe. Camshaft has a 108 lobe center and 248 @ 50 duration I/E.
I have had recommendations to use the least restrictive muffler possible because the overlap on a 108 lobe center hates exhaust backflow.
Summit makes their own mufflers, for example, one at

Anyone know if these mufflers are "straight through" designs? They say "turbo style", not sure what that means. Or anyone know anything about their flow?
Thanks!

I run Edelbrock RPM 3" mufflers that are a straight though design.Flow like crazy,but more like $85 a piece.Not too loud under light throttle, but sound like straight pipes under the gun.

That is almost too good to be true!

Summit says:
I say:
Who was the leading competitor? Which muffler of theirs? Roll seams = cheap and leaky, prone to rust. Aluminized is nice, but mufflers rust from the INSIDE out, so an aluminized EXTERIOR does nothing. Spot welded baffles, huh? How else would they attach them? Glue?
I also say: Cheap is cheap. There is an old saying among manufacturers...Cheap, fast, good: pick two.
We knew our Summit Turbo mufflers would perform before we cranked up the dyno. But when one of these mufflers produced 21 horsepower more than a leading competitor's muffler--well, we were floored. Made with free-flowing large diameter tubing, they give you a deep performance tone without being too loud. Features include roll-seamed end caps, aluminized external construction, and spot-welded inner baffles. Best of all, they're 100 percent American made.

Brettmc--those look interesting. ANy idea how loud they are? They say they are not glasspacks, but I don't think I want anything even REMOTELY close to glasspacks.
Looking for good flow, cheap price, and not too loud
Thanks!

Something else to consider is that a turbo muffler at the end of the exhaust like a C3 or a car w/ exhaust cut off before the rear end would be louder than same w/ tailpipes.
So I guess it is not a "straight through" design and it cannot possibly hope to compete with a straight through design in flow rates?

I have a set of the "fully welded" version of the summitt turbo mufflers that, I would like to sell. The set I have are the offset inlet, center outlet. If it were not for the offset, it would be STRAIGHT thru. Other than the shift for the offset, I can look straight thru from one end to the other.
The set I have, have never been bolted on the car. I slipped them into place and fired the engine. They are a little louder than I wanted. I ended up going with the Dynomax super turbos. So I will make you a great deal on these barely used Summitt mufflers.
Let me know,
Mike

If not, how much were they?
