V8 exhaust tone difference?

Hey guys,

I'm looking for a little input on my upcoming exhaust set up. I personally love the deep boomy all low end sound of a dumped exhaust before the differential. But this time, on this car (1995 BMW 540i) I decided to run a full length exhaust system with a tip out of the cut out in the rear bumper.

This V8 has a very Mustang sound to it. Maybe a bit more euro.... a euro mustang mod motor sound.



I've decided on a single 3" system for this car using a Vibrant Ultra Quiet resonator and a Flowmaster Super 40.

The headers Are 2 cylinders per down pipe. Then it's a 4-2 after the collectors. Then a typical y-pipe into a single 3"





What I haven't decided on, and would like a bit of feedback on is the muffler placement.



Should I :

A) Resonator mid mount, Flowmaster at the end with exhaust tip mounted directly to the FM

B) Flowmaster mid mount, Resonator at the end with the tip

C) Resonator before Flowmaster both mid mount with tail pipe

D) Flowmaster only, mid mount with tailpipe

E) Flowmaster only, rear/end mount.

The goal is to have an aggressive loud, boomy, deep sounding exhaust with minimal rasp.

Something to compare it to: This is the previous dual 2.5" exhaust with Magnaflow glasspacks going into a dual in/dual out Flowmaster super 10 dumped before the differential.

Appreciate your feedback. Cheers.

Option A. The further forward the resonator is the less rasp you're going to have, and also less drone inside the cabin

Really glad to report that the FM S40 will fit in the rear bumper area of my project, I was concerned it was too large of a case to fit back there. But alas:



The exhaust tip will get trimmed down to tuck in a bit more, but I will need it to stick out a bit as this car spits fire out of the exhaust at throttle tip-in after deceleration.
