I took a quick look/feel this morning, and it looks like there's definitely something under there between the two down tubes that would potentially block a standard DE y-pipe. Although, maybe you could just hang it a little lower. If I had easy access to anything but a hand jack I would take pics asap, but I'm not sure how quickly I'll be able to borrow one. Any other X owners want to chime in? My factory warranty was up in October of 2008, and it's a 5yr/60k deal right? So does that put my build date at somewhere in the fall of 2003?
I would imagine that the pipe that seems to be on some X's must not be as efficient as the HR's right? Why else would Infiniti not just put it in all sedans?

To those with a coupe midpipe...
How hard is it to bend the necessary heat shields during install? I'm going to need to have a shop put on my y-pipe due to the rusty nuts and bolts. After that I'll have fresh ones on either side of the midpipe so I can get it on myself, but I'm wondering if I'll be able to just bend the heat shields by hand or not? I've never really looked at them. My midpipe won't be here til next weekend and I want to get the y-pipe on beforehand so I can see if there's a difference between whatever one is on there now.

My 2004 x had the same exact "T" pipe as what's shown in DaveB's picture on the left... and have the same 07 HR Y-pipe.. not DE that is on the right in the picture.. no fitment problems at all. The exhaust system changed in 05/06 for the sedans... smaller mid pipe(half the length!)... bigger muffler... so the DE Y-pipe for these model years may very well have been modified also... no info to back that up though.. but it would make sense.. if the rest of the system was modified then.

These mods are not so much about awesome HP gains, but more so having to do with sharpening up the responsiveness of what you already have... across the entire power curve, as well as bringing out the "throaty" sound of the VQ engine as well. At least on the sedan, in combination with the 06 sedan mid-pipe, the exhaust note is really sweet, without any drone.. nice and deep, not quite as deep as a coupe or Z exhaust note.. but pretty dang close as we can get.. and still maintain OEM hardware!

I just bought an HR Y-pipe from a guy on my350z for my 2005 6MT Coupe, it should be here on Friday. I'll be getting some HFCs in the next few months as well. I'm hoping I may see some modest gain with this and my other breather mods (Z tube, k&n drop in, MD 5/16 iso, MREV2). Does anybody know of a less restrictive stock mid-pipe I could put on as well? I guess this exhaust is all temporary anyway, will probably go with the FI exhaust in 6 or 8 months.

so how much louder does it make things with the windows up?

YES!... the past several days it's been Springtime in Columbus, so the engine seems to really have opened up and resonates that fat VQ sound.. but yet last Wednesday I took a day trip to Akron, clocked about 300+ miles for the day.. and it was a very mellow ride with windows up at 70 (or so... ).. and purred like a content cat all day long.. seemed to pull about 23-24 MPGS... not bad, seeing how I was pushing 80 on the Interstate.. then drove home through a rainstorm on the way back.. but all in all.. the car was awesome on the road.. a cruiser on the highway... very responsive at the touch of the throttle... big thumbs up to you DB!!
BTW.. I've gotten some good responses back on the Fat Boy cans!! it just looks like they were meant to be OEM on the G!
