Title: How big a build will V&H powerduals support?
Post by: guesscrazy on September 24, 2019, 05:41:54 AM
Getting ready for offseason motor build on 2014 103 wethead. Going to do the 110 drop on if the crank checks out. Will do a 124 if it wobbly. Bike has powerduals already. Will these pipes support either builds or should I start looking for another exhaust?

I had the Kuryakyn version (same pipe) on my 2003 all bore 107".  130TQ and 120HP with Khrome Werks 4" mufflers.  Only thing holding back the HP some was a 50mm TB.

You'll be just fine with a 110" and probably fine with a 124"

A few years back one the tuners said he's seen that pipe support 140hp.

I enjoy mine so much that I'll just use them no matter the build size but yeah, I'm wanting to build the same. 110 if the crank is ok, go 124 if I need to split the cases.
