Anyone used the VTP 55-60 M8 manifold and had a chance to compare dyno numbers against an SE or S&S 55? Wondering how much difference it actually makes?

Like all other choke points.  If the manifold in the restriction........

I get that. Just wondering if there is enough bang for the buck if you already have an SE55.

If you've already replaced the stock plastic for any of the aluminum options, I'd say you're good. Even swapping from stock to one of the aluminum options, I doubt you would ever feel the difference in a manifold only swap. I'm sure you would see an improvement on a dyno, but doubt it would ever be felt.

I was told that the dyno would show maybe one or two hp increase at best just adding a SE manifold to replace my stock plastic one all things being equal.
This was on my 124 build.
I did it for peace of mind as I usually ride in hot climates and really don't trust the plastic ones.

Same.
I installed the se55 immediately as it can get pretty warm here. No seat of the pants difference. Just peace of mind. The dealer at first said I'd need a tune but then said I wouldn't.

Thanks
