Argon and Stargon and Oxygen will make my girlfriends honda go faster right?!?

The flange from ATP was not flat (about 0.075 out), so I fixed it.

And you know, some other pictures...

I think I'll likely end up with a booster delete for exhaust clearance. It would probably be fine if I was running a center exhaust, but it needs to turn toward the drivers side for the side exit pipe, so it's even closer to brake master cylinder. I foresee downpipe wrap in my future....

That thing is going to spool like crazy.
Also, LOL@ATP. I can't wait to see what you come up with for a downpipe, are you still dead set on using that sidepipe "muffler" thing?

I don't think you understand exactly how short this exhaust is going to be. The 2.5 is not going to be any sort of restriction 
Also, the 3 -> 2.5 transition is a beautifuly smooth Burns conical, not some FLAPS pipe expansion transition. Its not going to be an issue.
