The Original Exhaust Wrap Protection

Design Engineering Inc. specializes in heat and sound protection for every powersport application. DEI premium exhaust wraps are designed to keep heat contained within the metal pipes of the exhaust system. This keeps the heat expanded longer increasing the velocity of gas flow out of the exhaust header and exhaust system mufflers. Wrapping your header pipes with exhaust wrap can reduce ambient temperatures by up to 50% while providing additional horsepower, engine protection and rider comfort.

All of our exhaust wraps are woven using the highest quality materials, right here in the USA. DEI offers a selection of stainless steel ties and clamps to secure the exhaust wrap to the headers, DEI HT Silicone based paint can be applied to any of our exhaust wrap products. This spray helps seal out the moisture and provides additional fraying resistance. Online at Design Engineering Inc.

    DEI stuff is awesome. A great range of products and serves it’s purpose well for many applications,
    I love it BUT….
    has to be mentioned! So many people don’t consider this regarding wrapping & often moisture gets the major part of the blame when the exhaust seems rusted out and/or holey after only a couple years(at best) but it’s not moisture as the sole contribution! & don’t blame the Wrap or the Exhaust producer.
    If you do a lot of LONG PERIOD high rpm riding / highway travel… wrapping is not the smartest option for your needs! Think about this…
    Drag racing or Short Rides/Short bursts of racing… totally fine! the exhaust metal gets to cool off from time to time.
    Constant long hard riding… the metal doesn’t get to cool off enough when wrapped up and reaches temperatures within the metal that starts to break down it’s composition… somewhat fatiguing or crystallizing it’s properties and limiting it’s life.

    Wrapping an exhaust can give you many years of great service if you understand and use it within it’s design : )

    Wrap stainless steel. Don’t wrap mild steel.

    Yeah, well I have this wrap on my high performance Road King. Looks the business and is lasting very well.

    BobS, Stainless steel for a rust prevention yeah but might not be a saving grace considering the effects I wrote about…
    melting point for stainless is similar to mild steel… Stainless headers are rarer so I haven’t seen or heard much of the effects on them being wrapped like mild steel…I could be wrong but I think life expectancy would be similar??

    Titanium on the other hand could be best but as most know… that’s expensive stuff to play around with.

    Would be interesting to see some research and testing & such results… I don’t mind being proved wrong if the truth can be known : )

    In reality… if you like & want the look and benefits of wrap…. go for it… Buying new pipes every few years ain’t so bad, most people buy a whole new bike every few years anyway… I just mentioned all this to help some people be more mindful of such circumstances… I have seen guys who I know ride hard for long periods cough up for new pipes within 12 months.

    I think you are not explaining it totally but heat the steel to cherry red or hotter and hold the temp and you burn out the carbon content amongst other things. Chuck a can in a furnace and heat up cool down a few cycles and the surface hardens and cracks of each cycle.
    The wrap was also favoured and still is with car racers (amateur level) to keep heat in the pipes not the engine bay. Look at all the cars with intercoolers these days, air density is king and even more so in an engine with low volumetric efficiency.
    Personally I prefer deep blued chrome blending to a rich gold but for the vintage racer look wraps the dogs bollox.
