Has anyone put one on the dyno to see exactly what improvement there is?

Kayla has a 2 into 1 exhaust she sells and on eBay there is a dyno result showing 80hp. I had a similar system with FCR's and was getting 87 hp..

Expect at least 10 bhp on a stock motor from fitting the 41`s.

Got some pictures of your carbs fitted and your dyno readouts mince ?

I did post a dyno sheet a couple of times, one a mobile dyno that gave 88 bhp IIRC and the other a static at YPE that gave 88.1 bhp.
Dandywarhol has seen my TRX with the fcr`s fitted, we talked of the merits (or not) of single sock filters over the doubles and the issue with wasted fuel mist at tickover.
He had his hands about me carbs don`t ya know!
