matthimself456 Posted April 10, 2013 Share Posted April 10, 2013 I am just about to replace the famous split Passenger inner CV boot. Mine was damaged by heat even with stock UP/DP and all shields in place. It has me considering trying to fix the problem with a more permanent solution. Some VW's and FWD GM cars have sheetmetal heat shields around the CV boots but I don't see that being an easy fix. I am wondering why I can't use silica/mylar fabric to make a flexible boot to go over the rubber CV boot. A similar material to what fire suits are made of. It seems like this would be able to reflect a lot of the radiant heat coming off the exhaust while being flexible enough to allow the CV joint to articulate. Maybe even something like this: http://www.speedwaymotors.com/Thermo-Tec-16000-Fire-Proof-Shifter-Boot,51155.html could be attached over the rubber boot. Thoughts? Should I just try it?

bnguyenbb6 Posted April 10, 2013 Share Posted April 10, 2013 That is fire resistant, not heat resistant. You should try wrapping your up pipe and down pipe with exhaust wrap to hold heat in. Link to comment Share on other sites More sharing options...
matthimself456 Posted April 10, 2013 Author Share Posted April 10, 2013 Yes it is fire resistant but it is the reflective mylar surface that reflects radiant heat. It is the same material that thermo-tec uses for their heat-barrier products. Wrapping the exhaust is a good idea too. It creates some corrosion concerns, especially where the wrap will be soaked with salt water frequently. Plus I have seen members here and on nasioc report heat damaged boots even with wrapped exhausts. Link to comment Share on other sites More sharing options...
