what is the best bang/4/buck on mufflers for a stout 340?

IMCO is also the company that makes the exhaust kits that summit and Jegs sell. The kits come with mandrel bent pipes and IMCO turbo mufflers for a little over $200.

I put this exhaust on my car last winter in place of the compression bent pipes and Flowmaster 50 series mufflers. Can't tell and difference in power as measured by the butt dyno but the turbo mufflers are quiter at cruise and have a smoother tone than the Flowmasters.

I accomplished what I set out to do; quiet the car down when cruising while not adversely impacting the power and still have a sound that says muscle car.
