I thought I would give a shout out to the awesomeness of the M&K 2 in one out muffler. I recently had rear end damage repaired on my '68 and the shop recommended this muffler. I was a little wary as I had a stock Bischoff before. But the shop gave me the option of switching it out if I didn't like it.

When I picked the car up I must say I am really happy with the M&K. Sounds like a stock muffler when not getting on the gas, but when the loud pedal is pressed the muffler lets out a ripping wail with very pleasant over and under tones.

Combine this muffler with the new SSI's I also got and my '68 has been transformed, especially from 5-7K RPM's.

I love mine and I highly recommend this muffler!!
