I'm going to have a local shop fabricate a custom SS 3" cat back. I'm getting a baffled, cut and rolled tip but haven't decided on the muffler.

Looking for light weight, not too loud, and low pitch to take away some of the 4 cyl. raspyness. What do the listers recommend?

There's another thread that started yesterday on this topic Click Here

Yeah I just saw that after it got bumped next to mine. My question is a little more specific though. Not looking for a complete system. Just a single component. His thread also didn't seem to address weight.

Flowmaster = way to loud
MagnaFlow = Ok enough to not try anything else yet

I use a DynaMax UltraFlow 3" muffler on my turbo and the sound is low at idle, and it has a melodic growl at upper rpm's. I have no catalytic conv either so I am sure that helps. To be honest I prefer the sound of my B&B on my 84' NA but the turbocharger itself does cut down on the sound a fair amount. Although, the Callaway does have more interior resonance but it allows you to hear the deep rumble at cruise which I like! ZERO raspiness too!

Charlie - How about weight on the DynaMax and B&B?

Charlie944

That a close one. Whereas the B&B muffler is longer the SS sleeve that embodies the mesh core and fiberglass wrap is of a thinner guage then the Dynamax which is shorter but uses a thicker guage metal. The B&B has its own tip already with the muffler where the Dynamax leaves you the option for tips. I would say the Dynamax by itself in 3" config oval style is ~6-7lbs and the B&B with tip is around 7-8lbs. Keep in mind the B&B for the 951 is only 2.5" Inlet with a 4" elpitcial tip. And I am not sure if you can get a B&B muffler with out getting the rest of the 2.5" SS catback pipe as well. I have the full 951 catback on my NA.

get a big straight through, the more fibres they pack in there the quiter it will be.

This would be similar to the stock muffler correct? Who makes them?

local muffler shop supplier, http://www.themufflerman.com.au/
not sure what brand it is, doesn't have any markings i can see, locally manufactured i think anyhow. I was so happy to get rid of the flowmaster peice of junk that came with the lindsey exhaust.

flowmaster = bad on a turbo car.

I would suggest something straight thru. I like my Dynomax Magnum Bullet Muffler. I'm not sure how loud it is w/o a cat.. but with one its not to bad. I'm installing the Cat bypass tues so i'll let you know then.
