ideally you want to make the manifold as long as possible, then create a cat section to match. The standard join position is poor / not great / terrible, delete as appropriate 

 

More designed for the production process of Astra's than mid engined sports cars.

If your car is supercharged, you just want a chunky, 4-1 manifold with large primaries and a 3" merge. The 'fancier' 4-2-1 is more for those with NA engines who need all the help they can get

I run SC with the TMS 4-1 version which fits with the boot intact. Notable increase in torque but also in noise which may not be too all tastes.

To be fair if I could find a second hand one and save myself the hassle I would. I'm not a fan of doing things for the sake of it.

Yeah, second most expensive item I bought for my car (the first is WebCON ITB set). Not ideal (I would make longer primary and change 1-4, 2-3 order), but it's made indestructible. I talked to the maker last year, he dumped all the mock-ups and measurements, so it remains one of a kind. I will have clam off soon (as pre-spring "maintenance), if anyone wants additional view/measurements.
