Stainless Tubular Headers $300 shipped Options

[KOU In3]

Thought I'd post up on here in case anyone was interested. I'm running a group buy on these over on DSMtalk but anyone here is welcome to get in.

SSautochrome has 30 of these on hand available for us in a GB. We've got over 10 buyers currently so the price has dropped to the lowest amounts.

We're looking at $300 shipped for the Mitsu flanged version
or $320 shipped for the Garrett flanged version with Tial WG flange.

Pics, dynos, and reviews can be seen here:

We did see a 20-25hp gain on the top end.

Not sure how much everyone here has followed things so I don't want to deluge everyone with old information. But I'd be happy to answer any questions or assign GB numbers to anyone that wants in on the GB.

That's an interesting theory and well within the realm of possibility. Do you think there was that much unburnt fuel? Because when the throttle is closed and there is still a load on the engine, the injectors shut down completely. I've seen this on datalogs.

Since the gasket between the manifold and turbo was all good, I am inclined to agree with you, though.

It also may have also been a combination of the two. After reviewing the video a few more times, I notice there is smoke most definitely coming from where the manifold meets the turbo. I suppose this could be some unburnt fuel escaping then it hit the manifold and ignited. I just can't see it all coming from the head because it burns along this smoke cloud starting at the manifold-turbo junction rather than at the head at first.
