The toyosports actually felt 'ok' when the revs are up. Don't know if it was a placebo effect as the noise was different but definitely felt like it revved more freely

Would you agree Alan ?

Sounds ok! The backwards step is one of my pet hates and all too common.
Cliche, "If it ain't broke, don't fix it".
If I had to pick a point where headers start to get you somewhere, I'd say it was roughly 350 bhp upwards.

We get consistent results put it that way. I'm not saying there aren't any out there that just might offer better flow, but they don't actually cost power like some we've seen!

We did try a set of Killer B headers that Martyn found impressive, as usual, back to back might reveal more.
