The one I am looking at is slightly different part number 29500-000
One word "Hilltop"
Always wondered what they did. Thanks Roger.
Not cheap either.
I ended up like oldnfat. Not literally, y'understand.
Tried all the usual things with the exception of a remap and ended up with a standard exhaust and AF XiED units. Sorted.

About £280 from nightrider in the USA. I have no connection with them so trust me when I tell you I have had all the decat headers, end cans, remaps and power commanders and the standard exhaust and headers with the AF units fitted (very easy to do) is by far and away the best option.
Is that for the pair or just one unit?
Will they also work in cars?

That is considerably less than a Dyno remap especially when you factor in 2 tanks of fuel and overnight costs.
