you guys are funny. But i agree that you need to find out about that 45 degree coupler. I agree it should have the bend like every other pipe, but thats probably why this one costs so cheap. Might be due to the elimination of the bend, or the coupler not being included.
on the one i have the mazdaspeed cai coupler works fine, i dont need an angled one, but then again mine has the bend at the top.
For you guys wondering if the turbo inlet is worth it. It made my bov seem quieter (which I hate) but as soon as your car starts hitting boost this b**** is loud. The turbo is much much louder and your intake should be louder as well. Its ridiculous the change in sound. As for a gain, it may be minor, but you can certainly feel it at WOT. The turbo does spool at a lower rpm as well which can be a good thing or a bad thing. Means you'll probably get worse mpg if you're a daily driver like me since you'll get into boost or closer too it much sooner and you will probably loose traction sooner than if it was the stock part.
all in all a worthwhile part but can be a pain to get installed in there.
