Looking for mufflers for my trans am with the olds 403. Im more concerned about flow than anything. Loudness doesn't bother me. I was going to go with the flowmaster 44s because I like the sound but ive been told they dont flow well. Any suggestions?

 

Published tests say to use Walker Dynomax turbo mufflers for best flow. Here's what they sound like on my W-31 350 motor. http://www.youtube.com/watch?v=jeZAoQg035w

 

is a dynomax super turbo muffle the same?

 

Sounds good

 

Yes. My Part # from Summit Racing was WLK 17732

 

can you give me the link to the tests? thanks. Nice vid by the way

 

IM kinda leaning towards the dynomax ultra flows now. From what I hear the 3" versions out flow just about every other muffler and they sound pretty good too

 

Do not remember which magazines published them, Joe P. may recall, he's read them. The last book I saw them in was one of the horsepower engine build up materials at Barnes and Nobel.

EDIT: found a chart:

 

I also have Dynomax and yes I have the 3". Love them!
