Right, now I understand - the hole won't be parallel. but there should be plenty of room for 2.5" pipe inside a 4" hole. It will probably need a reasonably tight bend to avoid the flange, but not enough to be a problem.

John boy..... Oh Johnny boy... ( I was looking for a whistling or singing emote but seems we do not have one )

Man that underside looks clean. Come up real nice.

Fuck yeah! That's how it's supposed to look!

Also, on the cross member hole, you guys got me worried now... I need to go check mine.

If you want you could measure up that pipe and we can run it through the chop saw and clean it up on the lathe, you cold also die grind an egg shape into the cross member so you can weld it on an angle in the direction you want it to go

2-3mm on each side would would a pretty nice angle on that thing to help with clearance.
The Answer to your Question is NEEDS MORE VG30

Ginge, have you not enlarged your exhaust hole yet? The original hole is just barely 2.5" so with the 3" exhaust I'm guessing you want you'll definitely need a 4" pipe too.

Thanks for the offer James, I think I should have more than enough room going straight through though - just need to get that hole cut out somehow first!

My crossmember hole was 3" so with my 2.5" zorst fits pretty well. I I think I have 2x 2 bolt flanges at either end of the zorst section going through the cross member too

Weighed up the pros and cons/potential risks and decided to go for a surge tank instead of an in-tank pump. Of course no off the shelf surge tank will fit in the space I have available underneath the car, so I'm having to make one.

First step was to have a quick measure, attempt to bend some 5mm alloy plate in the shop press at work and fail miserably. Ended up making a rangi vice-mounted press brake thing out of some 50x70 angle iron and Bunnings hinges.

You'd think bending this stuff would be easy, but it actually takes a lot of force to bend. Surprisingly the pieces turned out really nice, shame I scarred them up so badly with my previous attempts. I'll definitely keep this bending tool and use it for brackets etc. in the future.

Also my JIC weld ons arrived from aliexpress today. When I'm not so poverty stricken I'll get some more argon and try to get back in the groove of AC TIG welding. No excuses really after I bought the fancy machine and everything.
