Aren't they worth more than 5hp? Maybe 50? :mrgreen:

I remember reading somewhere that the 'S' would run a tiny bit faster than the Roadster. Wouldn't surprise me if the SS would too, but how much? Probably only a dyno could tell.

I have seen the difference on the dyno.
You can also observe it on a flowbench. If you have a stub exhaust with a 90 degree bend similar to a stock pipe you can rotate it so it is pointing down and see the flow go down and rotate it to the side and watch it go up. Jim

In my experience the SS pipes with Dunstalls work best, followed by the balanced pipes, at least on my ancient Combat--the latter are worth one or two BHP and MPG. The SS setup seems to be less sensitive to tract length than any configuration I've tried.
