My New Headers

I would think Porsche thought about how these cars would be daily drivers and they didn't want any resonance issues,which I think the headers add.

I thought that resonance is cancelled out by the muffler?

One must never forget that these aftermarket headers are made out of stainless steel, not cast iron like the originals. Therefore, they "tick" a little as the steel expands and contracts, most noticeably at idle.

My passenger side header, sent from Che last year, had a true leak in the collector and had a hissing sound under hard acceleration. Of course, he swapped it out immediately and without question. There was an hour of labor I had to pay though to get it swapped.

Any aftermarket headers should be checked for leaks before you install them to save money, especially these eBay parts we're putting on our cars. When I got the replacement header, I used packing tape to tape up the engine side of it really well, cleaning the surface with alcohol before I taped it up.

Then I blew into the other end while my wife listened for possible air leaks in the collector. I huffed and puffed and could not find a leak, so I had it installed.

Killer price, by the way. That's like $400 off, no? It's nice to see parts for our cars coming down in the realm of reality.

What part of the header is the 'collector'?

[RandallNeighbour]

The collector is where the three pipes go into one pipe.

Im not so sure about the clicking randall, its only on acceleration it will kind of fap fap fap, idling it sounds fine.

[RandallNeighbour]

Oh, you didn't say "fap fap fap" earlier.

That's a completely different thing altogether, isn't it?

You may have a collector weld that didn't quite get into the tiny corners. I'd get that one swapped out with the seller.

We can't have our cars making fapping noises on acceleration! That would drive me nuts.

UK people will have fun with that.

This is so wrong on so many levels.

.

The Porsche factory headers are not cast iron they are steel may in fact be stainless, just not polished, at least the 996 ones are. The last cast Porsche manifold I have seen was on the early 944.

Thanks for the fun fact. If I end up doing an engine swap I am gonna ask you for help, lol. Your only down the road. Think we can do it for 5 grand?

[tholyoak]

You can do it for not much more than the cost of the motor, if you are able to do the work yourself.
I just finished up a 3.4 swap, so now I can put the X51 motor in my car, and then it will be a swap of the old 3.6 I remove from my car into a new recipient.

Todd

Ok, So if I buy a 3.4 can I do it at your place over a weekend? I dont have all the necessary tools. And if I do a swap it will be after january if I can find an engine.
