I wonder if the difference between this and Stamfords is down to who did the remap.

Stamford has standard manifolds but a de-cat.
So I have better manifolds, but a more restrictive cat.
I suspect though the de-cat is probably worth more than Janspeed manifolds on a sports cat, That's why Stamford is about 4-5BHP higher than mine.
