I've never seen a negative CXR thread but I've seen lots for O3 .. Lots of fitment issues and ####ty customer service from what I've read with O3.. Plus their hot sides are mild steel. CX are all stainless, back purge welded.

I've been sitting on the TT kit for about a year now, getting all my part together. I took pics of it if you all are interested. CXRACING Slideshow by leadfootdriver | Photobucket

I went ahead and bought different Wastegates tho. These are way better and are still affordable.

My on3 kit fit perfect on my stock motor/mounts. I did a k-member that moved the engine 1" back and used mounts that dropped it an inch, which made the downpipe hit the firewall and front header hit the motor mount pad of the k-member. just had to grind on the pad and manhandle the downpipe and all fits okay again.
