Thinking of trying spin-tech mufflers. What are the opinions of spin-tech mufflers?

Thanks.

They sounded wicked cool on Jeff Kinzli's 67 Blown Chevelle :cool:

They have a cool sound and are very well made. We had them on my son's 65/454 Chevelle and they sounded great. He has since gone to a 3 inch system with Flowmaster 1 Chamber. His 65 is in my signature under Car Show if you want to here it.

Or this, Jeff's blown 67. http://www.employees.org/~jk/jeffscar.mp3
