Come on, how much can heatwrapping cost?

What exactly is used to heatwrap the exhaust?

I for one also believes heatwrapping the whole exhaust would overally makes the whole car perform a lot better and cooler.

looks like a bandage, it's some kind of fabric. You just wrap it up, literally like a mummy. Costs pennies, really.

Are you not afraid that heatwrapping the exhaust might cook the catalyser ?

Or reduce the power if the cat sensors detect a higher temperature and enrich the fuel mixture ?

Just a question...

i don't have stock cats so no idea about that. as for higher EGT, it won't be that much higher. and i'm fairly certain the car does not have a sensor to measure EGT at the tips anyway so what would it matter?

keep in mind when you initially install the exhaust wrap it'll really stink as you drive the first few miles. this is just the wrap "curing" from the heat of the pipe. After a few dozen miles the smell will go away.

i wrapped the exhaust on my lotus myself and noticed the same thing. after wrapping it definitely reduced engine temps, as it was mid engine.

i'm hoping that wrapping the gt-r will kill a lot of the cockpit heat and fuel tank heat sock.

to wrap the entire exist is plan stupid, water and road debris would kill it with in 1 thousand miles. Ceramic coating would be a prefer ed method to stop heat build up- but then again it cost to do so. There are many reflective self adhesive heat shield available and would be far more effective at blocking radiant heat as wrapping would have different side effects like the ones commented on.

i'm wondering if there's enough room for a full heatshield? i think ceramic is the way to go too but will be expensive. i'm going to speak to mine's to see what experience they have with this.

mindlessoath · 1st September 2008, 06:38 AM

please do! i have been asking around if anyone can get temps or even a comment on this subject and no one is bothering to comment on it.

I had my Amuse midpipe and exhaust heat wrapped before installation.

how well is this doing for you?
