Thinking about insatalling 'side exhaust'

[Belairbob]

I have been thinking about using a shielded side exhaust kind of like was on
some of the earlier corvettes. It would come out at the rear of the front
wheel and end near the back of the cab. Was wondering if ya'll had
any opinions on the nosie level, etc. This is on a 68 that I'm just starting
on. Will probably install a mild 350. Patriot exhaust products offer these in
different lenghts. Thanks, bob
