<VV> Sgl vs. Dual Exhaust

[Bill Elliott]

I agree with Geoff. If you use modern duals, you really need a crossover pipe. Otherwise you loose too much low end and the exhaust sounds ratty. But if 
you've priced 140 exhaust manifolds lately, you'll see this is not a cheap conversion unless you happen to have a decent pai sitting around collecting dust.

My two favorite exhaust systems for PG are either factory 140 duals or a single modern turbo muffler on the stock crossover. I've found the latter is the 
cheapest to do, sounds the best, and provides equal (or possibly even better) to the factory duals.
