Muffler Comparo
#1
thsi article (which was also in Populat Hot Rodding) tests a bunch of popular mufflers in flow,sound pressure,performance and hp. Its probably as complete a test as can be done by a third party and the writer of the article is highly regarded in more than just the pontiac crowd . It shows the Dynomax Super hemi muffler as one of the highest flowing and quietest mufflers in the bunch. The Blowmasters typically finish in the bottom of the bunch.. Like i always said..rather be fast than loud.. Smile

i imagine the summits are made by dynomax(or copies) anyways considering summit doesnt actually make anything themselves Wink

THANKS!!!

I think if I swap muff's I'm gonna go with the Hemi's. THey make SO much power, and are dead quiet. You cant go wrong with that!!! I could run a "louder" muff and you wouldnt know it on my car, it keeps things pretty quiet regardless. Even open downpipes, its not THAT loud.

Back when I worked for Navistar Engine Engineering, our air flow engineer (aeronautical engineer really) would invite people to bring in mufflers to go on the flow bench.
He is actually the 1 who told me that the DynoMax Turbos were THE BEST he'd ever seen, and also put the FlowMasters @ the bottom of the pile.
He flowed 2 1/4" for me when I replaced the sys. on my MK in 2000, and as a bonus, it sounded great.
Now that I'm going to 2 1/2", I expect the same results.
