Anyone running Edelbrock SDT Mufflers?
 

I've had mine for a while, but I'm thinking about changing them from what I've been reading about chambered mufflers. Anyone have more insight into how well they flow or if it will be worth my effort to change. I have dual 3" in/out mufflers. Thanks for amy input.

Anyone?

I've heard a few people on here say they saw big gains with a cutout open vs. this muffler. It doesn't sound like it flows very well. Might be similar to the flowmaster, but I don't have any direct experience with this muffler.

Yeah, I've heard the same thing about the Flowmaster and this appears real similar to me. I was just curious if anyone has tested this specific muffler.
