I know exactly what you're talking about with the 'nested' anti-foulers.

The helix ones weren't closed at all, it's just an extension with threads. I wanted to try adding the non-drilled anti-fouler onto the extensions but the o2 sensor wouldn't fit on. For sh*ts & giggles we tried the drilled out o2 anti-fouler, but that did nothing. One other thing I didn't like about the helix v2's is that the o2 sensor extensions are angled down slightly, maybe 5 to 10 degrees from what I remember.

I just read on another thread that BERK is about to design their own cat-back exhaust. I guess I'll be waiting just a bit longer to see how that comes out. If it fairs nearly as well as the Stillen exhaust, I may be going the BERK route for exhaust (I don't plan on doing headers in either case).
