Default Car Chemistry or Dynatec Exhaust Insert Users Inside Please

I am interested to see how much these type of insterts actually quieted down the exhaust, and if there was any noticable power loss after these were installed.

I will be running a pair of mufflers or bullets right off the collectors and I am hoping these would quiet the car down a bit without sacrificing a lot of power.

Any information or feedback is much appreciated.

Thank you



Ross

That can not be right. It clearly states on their website that there is no loss of horsepower or torque. You must have been using a broken dyno.

Back to back dyno pulls. Only difference was cutout was closed on one run and open on another. It necks your exhaust flow down to 1 1" hole with a few smaller holes in the discs around the main inner tube.

If you don't believe me then pics are worth a thousand words...........
