Are spintech mufflers chambered?

spintechs are LOUD........theyre not chambered per say....but they have rounded baffles (thus SPINtech) that are welded in a spining pattern to supposedly spin the air, i like em tho, they get my recomendation

I had the Spintech prostreet series with the Dr. Gas X-pipe. They are technically a chambered muffler. Like stated earlier they use a circular baffling design, not an absorbing design i.e. Dynomax, Borla, Magnaflow. They don't sound bad with a true X-pipe but with a chambered X-pipe like Bassani and BBK it will still make that rattling sound. The best muffler for the Bassani X-pipe is to use either Magnaflow, Bassani, or Dynomax. I had the Bassani X-pipe in the past and got rid of it for a h-pipe. So all in all I would get the Spintech, but change to a different midpipe. I have gone through all types of exhaust systems in the past such as h-pipe, Bassani X-pipe, Dr. gas X-pipe, Prochamber. I am now back to a H-pipe with a chambered muffler. In my opinion I think an H with the Spintech will sound nice and mean compared to the Bassani X-pipe. Everybody has their own opinion though. I am just speaking through experience. Hope this helps and good luck with you decision.
