Sidepipe comparison - Spiral Baffles vs. Classic Chambered

[Kit Coyle]

I have the Classic Chambered Power Sticks. They are straight through with no restrictions and no packing to burn up and blow out. The sound is, well, I
won't be sneaking up on anyone anytime soon!

My Cobra could be heard from one and a half miles away.

I changed to the Classic Cobra Pack 3" inside but four inches longer (28"). The old mufflers were 2 3/4' i.s. and 24" long.

They were a "lot" quieter. I could talk to my passenger with out screaming.
Nice healthy rumble.

When I installed them I cut a little off the front pipe and a couple of inches off the rear turn down tip to keep the original over all length. I did turn the tips up to keep the sound from bouncing off the pavement but not so high as to bother the guy next to me at the traffic light.
Worked out great and I love them!

thanks for the responses... I agree with my initial beliefs that the spirals are robbing some power..

overall want to maximize the engine performance as well as a new sound considering this is year 13 of ownership..

Jeff, I agree that car sounds great but why not a change for the next 13 years!
