Big Radius 2-1 dyno

[TCALZ06]

has anyone had these pipes on a dyno?

I can't find anything under search.
I know the 2-2 are not good for power but how are the 2-1?

Damn, does any other pipe do well besides the RB Racing 2-1?

Took a ride with my newly chromed Ghetto Blasters without baffles today. Didn't even compare to my 2 into 2 Radius's. They sucked, especially after the chrome bubbled off after a 1 mile run. :angry: It made me realize how important how having some back pressure really makes a difference.

Which ones are you referring to that suck and the chrome bubbled...the V&H or MBs? I been thinking about some MB pipes of some style.

My bud and I both have 07 RGs, both have exact same mods, dyno'd and race tuned by the same top tech at Harley. Sept he has rinefart true duals and I have LSR 2-1. We both topped out at 114 mph on the 6 mile flat straightaway, between vegas and pahrump, NV. I barely pulled away from him with the 2-1. My take, the 2-1 might have little better low end but no difference at the top, at least in our testosterone test. Get what looks and sounds good to you, the rest is a wash IMO. FYI, The dude at RB is convinced that backpressure is restrictive.
