After much debating I ended up going with AA signature exhaust, its just a tad cheaper than mpe but cost was no issue to me. Wanted to get rid of that metal dipper look that oem and mpe has and keep a nice deep v8 sound.
At idle to about 2500 rpm you have a nice deep vurmmm gurgle, will turn heads just at a stop light then when you take off they do a tripple take.
But once you get a bit of rpm up all that goes away and sounds just a weee bit louder than stock so trips or highway speed etc your cabbin is pretty much stock quiet.
Oh and downshifts sound sick!
