When it comes to the mufflers, you have to be careful to differentiate the brand from the model. Dynomax Ultra Flow's, Magnaflow and Pypes Race Pro's all have the same welded case, straight thru, sound deadener packed design and therefore the same sound. All three will have a significant drone at a certain rpm level.
However, dynomax also has a crimped case, non stainless Super Turbo muffler that is very quiet. Pypes is also working on a welded case version of that muffler and will be the first of it's kind on the market for anyone that will be needing a kit come mid Summer.
Pypes also has a 2.5" stainless system for the A-body as well as 2.5" stainless OEM style tips. However, currently we don't have the downpipes for the 340 A-body. Anyone want to volunteer their car for a couple days for us to design a set? :)
