Stop wasting your time with trying to ICE your way through it. You'll just end up blowing yr cash.
What were you gonna do, ONLY listen to the exaust with No music.
i'd recomend looking into getting an exaust built by a specialist, with a valve that can be opened (by a switch) which will open the exaust up fully when you wanna hear the sound.
(much like whats built into the the Sport button on Porsches and other perfomances cars). It is a lot more feasible, & will earn lots of respect.
This will can also increase your power at the low end (more backpressure) an at the top end (less back pressure), depending on whether the valve is part open or fully open
.
Not to mention, the fact that the sound wil come from where its supposed to.
By the way
Have you heard of Anti-sound, i remember seeing something on the telly about a new development that used a mic and a realtime processor to produce the exact opposite soundwave to completely cancel out the sound of the engine. The gizmo also had other settings that enabled the car to sound like a V8, V12, ferrari etc.
Actually, this technology is going to be in our cars VERY soon, as stricter Emmissions regulations are coming about, and manufacturerers are gonna shed Kilos of weight by removing sound deadening, and empoying this technology instead.
I read that in AutoExpress a 2-3 weeks ago.
This will probably lead to Silent Cars on the motorway, as these systems can also remove road noise.
exhaust 
. I reckon that the exhaust will need to go out beyond the exhaust to pick up the best sounds or near the engine itself.
