put a regular flowmaster on there, like a 40 series. they flow better then their crossflow design for our cars and still have the same tone. my wife's durango has a deltaflow 40 series and it has a great tone and it carries a long way.

this is what i would do run a single inlet 3" dual outlet 2.5" muffler like a flowmaster or summit series muffler (pictured) where there is no cross flow involved.

And run it the way magnaflow has their catback pictured, where one of the exits takes a 180* turn so it has tips on both sides.
That setup would provide the best flow and would still give that awesome sound. I think this setup would be similar powerwise when compared to most catbacks, you can kind of see the flow the summit muffler has according to the weld spots in the picture i provided.

Just run a cutout before the catback, then the catback will no longer be a restriction and you can keep the flowmaster sound!

Why even bother with the dual out muffler then, the 180 bend would still be a restriction. The Single out setups have always been more efficient.
Heres a pic of my Mufflex 3.5" setup with a Flowmaster 30 series Race Muffler.
It has the single turn down tip and makes for a clean rear appearance.

how about 1 chamber FM knock offs?

they sound EXACTLY the same as the 1 chamber flowmasters... but instead of being 100$ each they are 30$ each..

sound AMAZING! flow AMAZING!

that gets my vote hands down.. i love mine to death, wont ever own another exhaust setup..

just my opinion.. the 1 chambers are going to flow almost just as good, and also are going to be a bit quieter.. also, they are the same price..

any muffler that flows very good is going to be on the loud side... bullets, cutout, 1 chambers, etc..
