I was told someone built an exhaust system from motorcycle mufflers.
Any pictures or exact muffler model?
Does it quiet the gyro?
The age old question:
How do your quiet down the Modified Raf/Sparrowhawk?

Thank you in advance.

Motorcycle mufflers seem to be fairly basic designs, all the clever work is in the pipes from the engine to them. The thing is, though, that I've generally found car mufflers to be a lot cheaper than motorcycle mufflers - I'm assuming you're running a Subaru? There should be a lot of those mufflers about - you could even try Craigslist or whatever for one of the local guys who have "upgraded" the muffler on their WRX :)

Here is a link to one sweet sounding 1/2 vw with what looks like a motorcycle muffler. No details though.
