Well I've yet to hear a good-sounding, loud V6 - but there is one exception.
I was taking the mufflers off my twin 2.5 xforce (stainless) so I could make hella noise one day. It sounded okay but noticeably flat, or boring, kinda like someone had just turned the volume up... Nothing special.
I then decided to rip around with only one muffler on.
And it sounded *a m a z i n g*
It sounded like a true 6 should; just a visceral scream that keeps going and going up to the redline.
Of course, the drone was really bad so I unhappily put the second muffler back on.
Also there was a lot of soot around the gasket of the first muffler.
Perhaps this was due to the pressure difference (duh...).
I'm thinking that a small, single, merged exhaust would be a great setup on these cars, both 6's and 8's.
If it can make a v6 sound respectable then what about a v8 o_0?
P.S
I hate v6 noise. It is really the worst engine sound ever. However I do own a VE v6 and I want to make it special - after all, these cars aren't made anymore.
