I run both a mantzel and a janspeed 4-2-1.
R/R at TOTD
124bhp
117lb/ft

JUst the Mantzel was 119bhp.

But it's not just the power they both make together.
The mantzel is very peekky, add the 4-2-1 and it fills in the mid range revs upto where the mantzel works.
Both off them make the driving experienece much smoother.

Fit the box first you will notice the gain even with standard manifold , then improve this with the janspeed.

Do you think a local garage would fit it for me with it being a performance mod?
