As most SH owners will tell you, the downpipe likes to get ground up against the ATTS unit and create a nasty little vibration.... around 2500RPM for me. So while I am installing a Exedy Stage 1 clutch and Fidanza Flywheel (not sure if the 8.x pounder is what i need though?) if figured i would replace mine with an ebay special. $28 for the XTUNE Header and $40 for the shipping = whopping $68.


First, I notice the piping ends flush with the outer lip of the flange


..but not in the middle connection to the downpipe




...but flush again at the catalytic converter


Anyway, on to welds by a 7 year old chinese boy







Overall, not bad quality for the price. To be honest, I expected worse. I will say that the piping is SLIGHTLY smaller than stock. Anyone know if this could cause a problem?

Anyway, I will finish the review once installed. Which should be Sunday or so.

 

My eBay header had tiny piping too. Now would be the easiest time to do the 2.5" collector. And clean out that slag inside the down pipe

 

Can you get some measurements?

Like ID of the pipe at the cat. Also, ID of the primaries and secondaries?

$68 is pretty cheap, that's about the cost in materials right there!
