A: Hi Renae, this Dynomax Super Turbo Muffler - Part No. 17747 made of steel. Steel and Stainless steel are both alloys, meaning they are formed when metallic elements, two or more, are combined in order to enhance or further develop its properties such as but not limited to reactivity, density, thermal, and electrical conductivity, durability, and strength.
Dynomax 53804 Super Turbo Muffler Dynomax Super Turbo performance mufflers exclusive; patented; flow director design channels exhaust flow; and eliminates turbulence. The large internal flow tubes improve exhaust flow; and reduce backpressure. Each muffler uses fiberglass matting technology to absorb unwanted interior resonance; while maintaining a mellow performance tone.
|"Dynomax super turbo mufflers", are they much louder than magnaflow or flowmaster?|
The veteran strip-test mule was driven to E-Town with tools, tires, tti X-pipe, and Dynomax UltraFlo mufflers. The DynoMax Super Turbos were hangin' on the H-pipe for the ride. without tailpipes, the 90-minute ride was a bit too smelly and noisy.
This Dynomax Super Turbo muffler was installed on to a 1998 Jeep Grand Cherokee Laredo. The Dynomax Super Turbo muffler is a good fit. My Jeep Grand Cherokee Laredo had gotten VERY loud due to the old muffler rusting out, it had been on there for quite a long time! And this Dynomax Super Turbo muffler did the trick, it tamed the wild beast... My Jeep Grand Cherokee Laredo now purrs rather than roars. :) It was easy to install, the hardest part was removing the old muffler. I would recommend it.
