Re. Noble wiki

In the wiki there is a link to some dyno curves for the M12 with various exhaust mods. Has anyone got any links to similar curves for the M400 - particularly interested to see the boost curve for the 425bhp engine.

Before (dotted) and after (solid) curves from an M400 having the Roush exhaust fitted.

I've just got the curve for after installing the Roush exhaust dunno what it was before as it was a "new" engine fitted at same time as the exhaust.

Thanks for them.

[Mr Noble]

My before and after runs.

Its important to note that simply popping on the new exhaust won't make much immediate difference, it'll rev much more freely, but you'll need to get the car re-mapped by a pro on a rolling road to unleash the new power. Mine was a new experience altogether after the exhaust AND re-map.
