Heat shields

Iím getting a new exhaust system made and Iím considering doing away with using the heat shields.
Just wondering if anyone else has ridden with no heat shields on the exhaust and if the extra heat is a problem?

My Vulcan didn't have any when I first got it.
I would quite often end up getting a whiff of burning blue jeans when stopped at a light. Usually seemed more from the left side than the right.
I got a couple aftermarket shields and haven't noticed it since.

the only problem when considering Header wrap is, when the pipes are wrapped the heat doesn't escape along the length of pipe because the wrap keeps the heat in the metal. this causes the pieps to get real hot wheich then screws up the pipes manifolds. they usually use that stuff in race cars where distances aren.t long or /and the are always replacing parts.

aftermarket shields are the way to go best bang for the buck JUST mho

humm... didnt know that..... how does it mess up the manifolds? to my understanding, wouldnt a ceramic internal coating help with this?

Cool

I dont understand wrapping the pipes will have no affect on the pipes or the manifold at all.Your just keeping your pants from catching on fire.Best thing is to get heat shields...............

This is one of the types of heatshields I got. Ya gotta watch where ya use it though.
The tips of the flames can easily catch your pants leg.

the wrap doesn't allow the heat to escape from the outside surface of the pipe so the pipe gets super heated and deforms and weakens eventually. the heat by conduction will migrate from the pipes to the exhaust manifold and then the excessive heat can cause problems there.
the wrap kinda acts like an oven whereyou are cooking whatever is inside of it.
now if the interior of the pipe is ceramic coated then thats another story. the ceramic coating protects the metal form the high temps so the heat travels thru to the end of the pipe, so the heat isn't an issue. in fact some applications of cermic coating, heat shields aren't needed.

We had this discussion earlier in re: the MAC pipes, and I think the Forum was split. My understanding is that most after-market systems don't come with heat shields, so if you'll have to find the right size at your dealer or Ayers. For the short time that I had the MACs on, I wasn't into the possibility of burning jeans or flesh, and so purchased a small heat shield for the left side (which was perilously close to my calf). While it probably provided some protection, the shield I bought sat really close to the pipe itself - I'm not sure if I'd pressed my leg up against the pipe accidentally if I still wouldn't have been burned. Hyper's flame version (ironic, no?) seems to sit off the pipes just a little - might be a better option if you're really looking for some protection.

If Your Having The Pipes Costom Made You Could Have Them Bend Some Extra Pipe About 1/2" Bigger Diameter To The Same Dimentions Where You Want The Sheilds And Have Them Cut And Shape Them Nice (even With Your Name Or Vulcan/vn750 Cut Outs) And Weld Small Theaded Posts To The Pipes To Attatch Them To With Bolts?
