My favorite worm pix; twin turbo:





Not my car, BTW...

Haha, hey... I posted those pics first on H-T. Hoowah.

We probably got them from the same place. Mine came off some Aussie site. How about yours???

The only reason I ask is because of what BDC mentioned. He said some might consider it a bad thing to do...Just wondering why.

Question: Does using Exhaust Wrap on my headers cause premature header failure?

Answer: NO! Over the years, exhaust insulating wrap has received a "bad rap" (no pun intended) and has been attributed to header failure. Studies have shown that properly insulated headers can enjoy an equally long life as their un-wrapped counterparts. As the word circulated that exhaust insulating wrap worked for obtaining lower underhood temperatures and gaining a horsepower advantage, many users got wrapped up (that pun thing again!) into the age long train of thought, which is - "IF A LITTLE IS GOOD, MORE IS BETTER!" This could not be further from the truth.

Excessive overlapping, double wrapping, etc. completely "mummifies" each primary tube, thus decreasing their natural and needed ability to expand and contract as the exhaust heats and cools. Now perhaps you can begin to understand where these half-truth rumors originate.

Question: Why does the Design Engineering Exhaust Wrap have two blue lines stitched in?

Answer: We are the only manufacturer of Exhaust Wrap that provides this time saving guide line. The blue lines are actually wrap indicators which are sewn 1/4" in from the edges of the wrap. This helps act as an overlap guide so you can achieve perfect overlap during installation.

Question: What about year round usage of Exhaust Wrap on my daily driver?

Answer: Good question! As a performance enthusiast, you probably already know that your common mild steel tube headers are prone to "rust rot" with or without the elements - let alone salted, winter roads. We strongly advise the use of our HT Silicone Coating to coat and treat the exhaust wrap after it has been installed. This silicone based, high temperature coating, creates a protective barrier against road grime, oil, dirt and helps prevent water from being wicked up and held against your headers by the wrap.

Question: How do I fasten the wrap to my headers to prevent it from unraveling?

Answer: We manufacture Stainless Steel Locking ties for this purpose. They are neat in appearance and completely constructed of type 304 Stainless Steel. For more info on these ties, click here.

Question: I just installed your Exhaust Wrap and noticed the Wrap smoking after I fired up my vehicle. Is this normal?

Answer: Yes. It should only last a few minutes. What you are actually witnessing is the excess vermiculite "burning" off the wrap. There is no need to be alarmed, just be sure your in a well ventilated area.

Question: I heard that ceramic coatings offer superior thermal retention. I have also heard that Stainless Steel pipes attribute towards sufficient retention as well. If this is true, why would I benefit from wrapping my exhaust with your products?

Answer: While ceramic coatings and Stainless tubing offer good thermal retention properties above and beyond their un-coated and/or mild steel counterparts, coatings and/or Stainless tubing cannot offer as much retention as Exhaust Wrap. Exhaust Wrap offers the highest thermal retention for keeping underhood temperatures down to a minimum. Bar - None!

Questions: What kind of underhood temperature reduction can I expect by wrapping my headers?

Answer: Although our competitors claim 70%, we have tested theirs and ours and have achieved a good average of about 45%.

I guess you didn't check out the link I furnished above. No, big deal! I do the same thing...

Horsepower...

Wrapping also increases the thermal retention within pipes and subsequently expedites exhaust flow at a higher velocity. This characteristic increases horsepower.

Although Exhaust Wrap received it's claim to fame from renown engine builders and racers such as the late, great Smokey Yunick, it is not just for racing. Wrapping the exhaust on your RV, heavy duty truck or tow vehicle helps add horsepower while reducing unwanted heat in the engine and driver's compartment. Wrapping the exhaust can also protect surrounding wiring and hoses from premature failure.

Design Engineering's Exhaust Wrap is constructed of a high temp resistant woven fiberglass that is then pre-heat stressed in a process called burnishing. A vermiculite coating is then applied to act as a bonding agent and to increase durability levels under extreme heat - up to 2000º F.

Ah...Just saw this... To me for learning how to read...
