Sorry I was a little tired when I wrote this, do you think it would sound good to leave the flowmaster on and add a magnaflow crossflow muffler where the front resonator use to be? Or should I remove the flowmaster and just place a maganaflow crossflow up front where the front resonator use to be. I really like Wills exhaust sound. In the thread about a good muffler choice. I am a bit obsessed with sounding the best so I am willing to change exhaust setup. Except for the fact that he has 3 inch exhaust setup. Would that be giving him the deep tones that he has? Or would my 2.5 suffice on deep tones with a crossflow setup.

or should I lose the 40 series and place just an 80 series flowmaster up front where front resi use to be then go straight pipe the rest of the way back or maybe an 80 series to a 40 series? So many choices :(

Actually I don't think they make a muffler the way I want to use it. Dual in 2.25 single out 2.5

Woah.... Ok. Couple of ideas/thoughts. I would not go 3" exhaust. Your engine still needs some backpressure. 2.5" is fine. Deep notes sound good, hollow ones do not. In the old saying....there is no replacement for displacement, and displacement is what determines the pressure going through the system. Your not going to get a 6 cyl to sound as good as a 8 cyl HEMI. You can come pretty close though.

Flowmaster is a great choice, http://www.kmjent.com/cart/product.php?productid=5996 Any good exhaust shop will tell you the same thing. IDK what part prices are around where you live, but here most shops will install this muffler, just not offer any warrantee if you don't buy the part from them. This muffler will give you dual tips and is just a suggestion. You want to watch for noise inside the car. 40 series are aggressive sounding (meaning LOUD). Nothing worse than not being able to hear the radio over the drone coming from the exhaust under load. (That's what they make amps for right?!)

You'll have to make your own choices based on what you want. If you change the set-up you'll change the sound so trying to imitate someone else is virtually impossible unless you use the exact same gear.

If you do get rid of the front resonator, though, I would encourage you to move whatever you replace it with toward the gas tank and run duals from the down-pipes straight back to it.

300M Special has a 3" exhaust, nothing to worry about when switching - the car will happily take it and give you a little extra power in return.

Not that I would do it just for the sound, though. IMO, unless you continue using mandrel bend tubing it's not worth it so it's very cost prohibitive.

Is that saying the 40 is still behind the exhaust tip?

If so you might consider moving it to the regular muffler location before doing anything else. Part of almost any muffler's sound comes from the resonance through the exhaust pipe.
