2" x 50' Titanium Exhaust Heat Wrap Roll for Motorcycle - High-Temp Fiberglass Heat Shield Tape with Stainless Steel Ties - Perfect for Motorcycle, ATV, and Car Exhaust Systems Protection

I applied this on my car's exhaust (Toyota MR2 ZZW30) it was enough to cover the headers, the down pipe, and part of the Main cat. It was not difficult to apply but you NEED gloves and eye protection because the fiberglass strands are very tiny and could pierce your skin. I soaked the whole thing in water and it became a lot more manageable. The provided metal straps are not that good, you need pliers to tighten them and I used a Dremel to cut the remains. If you got the money, get better metal straps, if not, these work fine but you need to cut off the excess and they're a bit of a pain.Pros: After applying the wrap along with the factory heat shields there was a noticeable decrease in heat in the engine bay. You still cant touch the heat shields directly but inside the compartment there's less radiating heat. I also noticed how the speed of the gases increased and can be heard in the exhaust. Sometimes there's even a bit of backfire noise on deceleration.Cons: Tons of smoke on day one, had to run the engine for a couple of hours and rev it really high to let the wrapping get heated and release all the moisture. They also smell pretty bad on day one. After 2-3 days the smoke is completely gone but they still smell a bit. Everything is back to normal in around a week.Some people also say they can rust the exhaust if they get wet often because they hold moisture. I don't believe this because the pipes get so hot that I doubt they can stay wet for long. Still I applied high temp Rustoleum paint on the pipes before the bandages. I would recommend rust prevention or more expensive ceramic coating if you got a good exhaust system just in case. I didn't apply Silicon because the one I got is flammable, but you could try this as well to make them water proof. I still got my heat shields/covers and I avoid driving on the rain so I'm not worried.Good product, would buy again, Thanks!
