I've got the dynomaxes on the LRT....

It's a trick little exhaust...3" from the headers back, to an x-pipe, then 3" up and out, all mandrel bent.

I just had some work done by a local mopar shop and the owner went out of his way to tell me how much he loved the sound the exhaust makes...

It's loud enough to command attention in a parking lot driving around, but reasonable enough while driving/low throttle...but step on it and it gets impressively loud!

Nice i would love to hear a set of the longer ones and see the differance i have a friend building a 572 stroker Hemi i think he is looking at those.!






Quote:

On the same engine with everything the same, the 20" case Super Turbos measured about 2 dBA at idle and 3 to 5 dBa less at higher engine speeds, all at static conditions. Under load is slightly different but the 20" case version is most definitely quieter and less prone to drone.
Even though they are quieter, they allow as much air to pass through due to the longer internal sections that enable the air to smooth out after the flow reversal (my theory anyway).

67, he needs to look at the larger case versions (5" by 11" with 3" inlet and outlets) if he can still find them. The smaller cases ones (~4.75" by 10.25") with only 2.5" inlet and outlet bushings will have a tough time flowing enough exhaust gas to make the engine happy at higher loads and rpms.

Need a part number? 17769 is the offset center version that will fit the Hemi-powered car.

I have the walker exhaust 17749 on my daily driver grandma coronet, but it's just a mild 318. It's pretty quiet. I believe they are the same as the dynomax and a lot cheaper.

Anyway, here is a chart I got off moparts a while ago. I will be changing my flowmasters to these on my 383 RR. I love the flowmaster drone when driving alone, but you can't talk to anyone in the car.

You mean my charts from a few years ago? :)

For information, the bottom three are Magnaflow mufflers so the data is directly relatable to the current offerings.
