anyone used the new dynomax VT mufflers yet? i kinda like the valve design then have in it but wish it was more like the C6Z with controlable butterflys.

i think i'll pick up one to test out on my trailblazer ss before i get them for the camaro. i think i might just stick to my orginal plan of useing borla on the camaro though.

Tom Hand is an expert on muffler design and sound. His tests are very unbiased when it comes to flow and sound on mufflers.

hmmm, good reading. thanks for the link. i found one of his other posts that they do not recomend them on heavy moded or even mild mod engines.

I've heard the same. It seem on anything more than a mild setup, the exhaust pulses at idle cause the flapper to vibrate causing a decent amount of noise.
I'll also be watching to see how these mufflers age. That spring is thin metal. Heat, moisture, and fatigue may relegate them to the dumpster early if it breaks.

It is a very cool idea, I hope they can get these issues resolved.

I was reading on another site from one of the designers who said they don't flow well, even in full open position..

must be that stupid flapper valve.
