Wrapping header

[oyajicool]

My eBay header is wrapped with eBay wrap. I've had these for two years on my car. There was exhaust leak but it was due to faulty gasket than cracking.

I have Bisimoto header being worked on to fit on my car. When this is ready, eBay header will be replaced. I shall see if there is any crack on this one.

For wrapping, go with name brand. My eBay blue wrap held color for three days only. Then changed to tan. Still holding heat within, though.

wrapping headers is just asking for them to rust terribly. get them coated and keep them clean IMO.

My Bisi header is coated but leaks like a bitch outta the slipjoints so im thinking of wrapping the collector up

^header wrap w/ 2 large hose clamps on the outside and stuffing the inner w/ fiberglass rope was my best fix to date.

Just to note... eBay does not make parts.

Just to put some more input into this thread. I have a Hedmen header and it's been wrapped for years with no issues (warping, leaks, etc.).

Just because it can, doesn't mean it will. But the possibility is something that should be taken into consideration before a decision is made.

Exactly. Explore all solutions and possible outcomes to those solutions and make an informed decision.

I know I debated the hell out of wrapping it...

I think you have posted a photo of your header some place else on this forum. Mine is exactly the same way. There is way too much gap at left front slip joint. I don't think wrapping will help at all.

The problem with Bisi header is upper part of the assembly. The bends are originating from inside of those slip joints. Those sections are not true round because of bends.

I have asked my exhaust shop to correct that, possibly by stretching those sections. I hope it will come out good.

For a header of that price, and supposed quality, that really should NOT happen! It's bad enough that the "custom" header built to your specs comes with that connector that requires a flange to be made... but the actual build itself should be solid for the price, even if it was the $630 group buy price!



Anyway, on topic... wrap is fairly cheap, and no-name headers are fairly cheap. So wrapping a cheapie header isn't going to be the end of the world. If it cracks, it cracks. Drop $50 and replace it.

Lol that's a good way to look at it but yeah I ended up getting them wrapped so thanks for all the info guys
