procharger Posted December 16, 2015 Report Share Posted December 16, 2015 How many have wrapped their exhausts, how many feet do you need and what were the results. Link to comment Share on other sites More sharing options...

procharger Posted December 17, 2015 Author Report Share Posted December 17, 2015 I still looking for any information about results. anyone measured the temp difference under cowl? Link to comment Share on other sites More sharing options...
Roger Lee Posted December 17, 2015 Report Share Posted December 17, 2015 You wrap to reduce radiated and convected heat. If you run the engine and put your hand on your bare exhaust pipe you leave skin. If you wrap and do the same you can put your hand there and keep your skin. The wrap MFG says up to a 70% reduction in heat. I don't usually believe all MFG's claims, but when I can put my hand on a hot exhaust they have a valid claim. Before I wrapped many years ago my rubber engine isolator behind the #3 exhaust pipe was cracked fairly bad. Since I have wrapped no more cracking. The wrap will help protect your wire insulation and hose life under the cowl.It will also stop any blow-by at the exhaust knuckle at the muffler. It will not affect the EGT's or the engine performance. Header wrap was originally designed for racers to keep hot exhaust gases hot until they exit the exhaust pipe. If it cooled too much it caused back pressure which would cost them a very small amount of HP. I have now been using it for 8 years on my SW with no issues. I know many more that use it and have not had any issues. It comes in 50' rolls from auto parts stores. You'll use approximately 54" per pipe and takes about 1 hr. to do all four pipes.

Roger Lee Posted December 17, 2015 Report Share Posted December 17, 2015 Andy, Tell them how your exhaust pipe was. Post that picture. If you ever get a cracked pipe you'll know it wrapped or not. our pipes rarely ever just crack. They snap all the way across. You won't get just a small crack beginning and most likely wouldn't know it with or without the wrap. Link to comment Share on other sites More sharing options...
Anticept Posted December 17, 2015 Report Share Posted December 17, 2015 Our pipes have had small cracks before, but the exhaust gasses are hot enough it will drastically discolor the wrap and it will be obvious of a problem. Link to comment Share on other sites More sharing options...
Anticept Posted December 17, 2015 Report Share Posted December 17, 2015 Safe answer: yes Realistic answer: possibly, but IMO this is a tiny change that means a lot of safety which helps keep hoses from being burned through (had one that did get the fire sleeve damaged which is what motivated getting serious about it), and we're not changing any functionality. That, and LOAs take forever to get right now. Link to comment Share on other sites More sharing options...
procharger Posted December 17, 2015 Author Report Share Posted December 17, 2015 thanks for info think I will do it Link to comment Share on other sites More sharing options...
FlyingMonkey Posted December 17, 2015 Report Share Posted December 17, 2015 You can use stainless hose clamps, but I think the stainless steel tie wraps designed for header wrapping in race cars would be better. I bought some of these, but have not bought the wrap yet. http://www.amazon.com/gp/product/B004C3C22K?psc=1&redirect=true&ref_=oh_aui_detailpage_o05_s00 Link to comment Share on other sites More sharing options...
Roger Lee Posted December 18, 2015 Report Share Posted December 18, 2015 There has been an LOA for wrap for 7 years. There is a thread section here that has almost all the LOA's. use 2" wrap and it can be had at almost any automotive store. It comes in a 50' roll. Enough to do 2.5 CT's.
