i got 10m of that heat wrap stuff for $75 but as i dont want to pull my car appart i will have to wait till next service and get it all done at once. is there much prep needed in ceramic coating? And why do you stop at the cat, why not do the whole exhaust?

I don't think it would be necessary, aftermarket headers, ceramic coat, wrap, silicone coat, done.

benifits of wrapping post turbo? Other than heat protection....

hot gas moves quicker then cold gas.

tuna, did you use that silicone spray to seal it? do you have to clean the piping before you cover it? did you ceramic coat it or is it fine without? and can you install it from under the car or will it be shit?

I heat wrapped my new 3" dump pipe only. Not really for any performance boost, but mainly to protect the speedo cable and other various parts from overheating. I got 10m by 50mm wide wrap on a ebay auction for around $60. It was a proper auction not a buy it now price, and it seems to have helped alot.

When I popped my bonnet the other day, I could definitely feel the less of a heat wave coming out of the engine bay as I opened the bonnet. Plus I have a unboxed pod in the engine bay with a temp sensor, and I am seeing on average 2 to 3 degree drop from the standard pipe with heatshields.

I acutally used the whole 10m roll and double wrapped my dump pipe so that it has at least two layers of heat wrap on it.

silicon sprayed the headers only,
pipes were ceramic coated, so they were clean when i wrapped them, i wrapped them off the car so i could get the wrap as tight as possible... next time i'll do it with wet wrapping over some sheet plastic on the ground, the fibreglass makes you itchy otherwise

would this wraping and coating change the boxer sound or would it relatively stay the same?

i would think it would stay the same as your not changing the piping, you could probably enhance it if you only wraped the longer pipes though.

it quietens it down, but actually has more bark at high rpm (due to higher exhaust temps)

impreza_GT · #39 20-11-2006, 01:33 PM

thought so...is the quietning heaps obvious or relatively insignificant...its not gonna sound stock?????
