I promised to give you an update on the exhaust.
I know there has been many questions asked about exhaust systems for the ba xr8s.
The system: Dual 2.5 inch. Each pipe runs through a small resonator then finishes up at the dual in dual out custom made muffler. There is also a balance pipe put in (this is to stop 50% of the crackling).
The sound file can be found here (I only reved it to half throttle given its a sunday and dad was telling me off for reving it in the drive way.):
When stationary reving it blows the socks off anyone standing within close vicinity. Had very positive feedback from many by standers.
When gearing down the crackeling makes it sound unbelievable.
The only downside is that when in motion and the pedal is pressed to the metal, it gets quite loud at high pitch. Not the deep grumbling that most v8 lovers prefer. Probably more suitable for the race track than street driving. I am always concerned i might get pulled over when i hammer it. Best of all this system gives no drones whatsover and the bumometre tells me it accelerates harder.
I think I will go back and replace the muffler with something a little more conservative for everday street use. Something deeper in note with a little less bark.
If anyone else has sound files of their system please let me know as I'd love to have a listen. Lets work together and see if we can find a system that tickles everyone's fancy :o)
