I assume the removal of the engine cross brace was a temporary thing only for this install?

Thanks! Brace back on and here are the impressions:
I have to say, the difference with the new hose was dramatic. Moreso than the change after adding just the filters. Response, tip in power, torque, and sound all changed noticeably. Honestly it surprised me and I have a pretty well calibrated Butt. This leads me back to my feeling that the stock boxes are not the weakest link. What is, is the accordion hose and 2.5"ID path. Opening this to 2.75 is a 21% increase in surface area, Volume is increased, flow is smoothed.. There is still a restriction at the stock MAF holders which leads me to believe the additional plenum area the 2.75 provides is significant. Interesting that Nismo has chosen 2.75" tubes for their system. Fuel trims are still in line. I have a feeling there's even more power on the table with the enhanced MAf TUBES. More when I get these done!
