Steveo88, what are you doing to do to fill that space in the exhaust outlet?

For now I'm going to just space the exhaust so the outlet is somewhat in the middle so it looks "passable" but definitely not great. At the very least, I'll try to find some decent look mufflers possibly and welding it on to the stock piping to fill some of that gap. Other than that, I honestly don't know what to do, I thought about fabricating another OEM ISX50 tip onto my current exhaust to "resemble" the IS-F quad outlet but I don't have the welding knowledge to think of a way to rig that up. I'm always open for suggestions and ideas so let me know! For now, the bumper is going to get painted after the reflectors and tow hook covers come in.

ok heres my test results so far. I bought the IS-F bumper as pictured in the box above. I removed the OEM bumper to test the fitment before ordering the tips, reflectors and the towbar covers. The result of the test fitment is its a perfect fit.
Alot of people talk about a gap between the trunk lid and the bumper, this is not the case, due to the IS-F bumper being slightly different in that area it just reflects light in a different way and appears to be a gap but it is not a gap at all and even the appearance of a gap is not bad at all. Below are my photos of the test fitment. I have now sent off the bumper to the bodyshop for painting

This is what I've been saying all along - it's not actually a gap, just a difference in the top side of the IS-F bumper that meets the trunk lid. IMO you guys that do this need to do it all the way with the exhaust tips. That small exhaust coming through the huge hole the IS-F has for the quad tips is going to look ghastly if left as is. Just my $.02...

as you can see by the pics the bottom of our OEM IS250 exhaust tailpipe falls at the bottom which will be perfect place to have it output through the bottom section of the IS-F tailpipe. I will basically be removing my OEM tips and i'll cut the tailpipe so that it falls behind the IS-F tips.
Oh and another thing, the gap issue between the trunklid and the bumper is only visible in the photos due to the lighting reflection and the design of the IS-F bumper. When you actually look at it with your own eyes, there is no gap at all. It is maybe a mm or so more than the OEM bumper gap, and i personally prefer this because the OEM one is so tight that the trunk-lid starts to damage a bit of the bumpers paintwork

hmmm really dont know, but yea i wanna see it fully done with exhaust tips and everything, of course it would be a waste in my opinion to retrofit stock exhaust, aftermarket exhaust FTW!

Aghhh I wish there were more used parts available for this car ... It's just too new 
Are there any forum sponsors/dealers that would be able to give me a good price for some is-f tips?

Good Job guys!! ...........(Nice pics Lou..!! 
)
As I said many months ago...
From the Firewall Back an ISx50 & IS-F are Dimensional THE SAME.
Including the Doors, Roof, Entire Rear Clip, Rear Bumper, Trunk & All Glass...
In my opinion, if your'e going to get the IS-F Rear bumper, complete "The Look" with the OEM IS-F Diffusers / Tips..
That will save you a huge headache!!
* You will have to cut off the muffler tips from the oem ISx50 exhaust.
or
just go custom with a single tip or dual tip exit, with new mufflers.
For sure the mufflers do not line up in the same place, so something has to be modified with the exhaust to fill the hole...
Good Luck
