Heat Wrapping Info - Interesting read

Here's a nice little page I found with some info on heat wrapping your exhaust manifold, no doubt will start a debate but interesting none the less.

Hhhmmm its a good read, i dont really know what to say TBH but im still wrapping my system because ive just spent abit on a load of wrapping hahahaha

Wrapping manifold no

Will be doing my downpipe, front ext and the silencer though

[cazzac2222]

Yeah thats what i was thinking lew

and you can show off your sexy, racetech mani aswell

on stainless steel, i would say do not wrap, it will cause cracking, i had my steel mani done and it was horrid when i pulled the wraps off, on a decent mild steel "STEAMPIPE" manifold, like my current one, i would say go for it...

my boost comes on about 4-500rpm sooner, with just having wrapped the manifold, if i get a turbo beenie i hope to lower it some more...

as for the rest of the exhaust, there is really not much point except to make it look pretty, mainly because its after the turbo, so therefor it is effectivly doing nothing at all (unless u are only using it to sheild parts from heat, like on mine i have the dump pipe wrapped so the clutch slave cyl doesnt boil the fluid and fade my clutch off

Yes dont want that bad boy cracking either so no heat wrap will be going near it!!

Thats interesting mate can see why it would aid in spool up because the hotter the gases, the faster they flow. Same goes for the rest of the exhuast system though, the hotter you can keep the gases the faster they will flow so it does benefit to wrap the rest of the system aswell.

I wanted my full system wrapping but was talked out of it. He said about it catching and ripping on shit on the road. He had a few cars in his garage had a look underneath and it was all hanging off

yes and no, once its out of the turbo and in a 3 inch exhaust, your not going to be able to make the velocity much faster, purely due to the size of the system...

a decent exhaust shouldnt have to be wrapped on a turbo, as u want super velocity before the turbo, but after, u have no real need,

i had my entire exhaust wrapped on my s15, but it was titanium and i didnt want it scratched or marked, but wrapping it did nothing at all compared to without it, and i didnt wrap the manifold in that either, as i had it ceramic coated with a polished look and didnt wanna ruin the look of my engine bay
