Probably not a lot for peak power but it looks nice
Will be combined with a decat so the theory is you lean it out just enough to improve power. The Toda does show a mid-range gain its just hard to find conclusive data, especially as a lot of the comparisions Ive found are from the US so on the F22. Mid range is where you need more power on these.
The best chart ive found:

The standard tubular is 4-2-1 and good but like all S2000 exhaust bits it's heavy.
You can save about 30kg changing the manifold (5kg), decat (1kg) and system (20-25kg depending on type).[/QUOTE]
I know what you mean about finding data. [On the B Series] Some show TODA as the king making 13hp above OEM and others showing TODA making 1-2hp, guess there's a lot in it on older cars in different states of health but it's not gonna hurt.
30KG's :eek:
