yeah, that's what mine does. if it was perfectly horizontal, then the tip would be fine, and the etching on the exhaust tip (not the Ti tip) would also be normal. weird...

two questions:

1. The stock gasket from the midpipe that meets up with the hks exhaust seems too big. Basically it feels like it's sealing, but the midpipe and exhaust don't meet up because the gasket is so big... did you have this issue?

2. The exhaust tip just after the muffler (not the Ti screw on part) has the two holes that screw into the Ti part on at a weird angle. It's closer to vertical than horizontal. Did yours come this way too? (I can post pics later on of this if needed)
1. You should have no issues with sealing once the bolts are tightened. You will see more of the factory gasket because of the design of the CNC flange (on the HKS Hi-Power).
2. The reason why the tip bolts are rotated is because the actual Ti tip angle is rotated to fit the contour of the factory rear bumper better.

I hope this helps!

so you're saying it's designed to have the midpipe and hks not touch and instead crush the stock gasket between them? I'm just worried about the gasket falling apart from all the pressure.

That is correct. The stock exhaust does the same thing, it's just not as noticeable. Trust me, it won't fall apart as long as the bolts are tightened. Mine has been on my car for about a year and I've had no issues at all.

ok cool.

I'm strongly considering buying the 90 mm version of the active silencer now:

http://cgi.ebay.com/ebaymotors/Apexi...QQcmdZViewItem

The specs look like it'll fit into the HKS can. It's basically a standard silencer (a blocking plate that has a smaller pipe in the center that reduces sound (and air flow), but the blocking plate is sitting on a spring, and when the exhaust flows, it pushes it back, allowing the exhaust to flow freely at high rpms but without the sound at low rpms...

cause without a cat this exhaust is just too loud for me.

Have you thought about adding a resonator to your B&B catless midpipe? Without a CAT, any exhaust will be loud... even with a turbo. On my turbo, I plan on using an HKS Metal Catalyzer (which includes a resonator) and I'm pretty sure that will be loud too! haha

My catless midpipe already has a resonator installed...

I ordered the apexi active silencer last night, so in a week I should be the first one on this forum to have one to post pics and share
