[6pack] TR6 exhaust

[Jim Franks]

I'll agree with that, Rick. Thanks for sharing your testing results.

 A little backpressure on a NA exhaust is no bad thing in reality, and 
the exhaust size of the dual system isn't bad at all for most power 
levels seen here.

 One thing about turbo mufflers (as a guy who has tried several kinds on 
a Merkur with 3" exhaust)  The thing about turbo mufflers is that they 
have no / few baffles so as to give maximum flow. Why?  Turbo cars 
already have a muffler right at the exhaust outlet.... the turbo! This 
allows for minimal silencing in the muffler itself while still giving a 
reasonably quiet exhaust.

With an NA car you either need a couple of bends in the pipes or a 
better silencer to get the noise levels down. I personally probably 
would not like the result of a free flowing exhaust coupled with a turbo 
muffler on a street TR6. Keep in mind I like a fairly quiet car at 
cruise. What is intolerable to me may be perfect for someone else's taste.
