3 Piece Crank/ Spindle Help!

[skrew37]

I have a 3 pc. Primo Hollowbite BB/crank/spindle setup and since I decided to add a tuned pipe/expansion chamber, I'm having major pedal clearance issues. I don't want to reroute the pipe higher because, well, I don't like how it looks for my specific bike. I see that Bikeberry has the wide crank setup for just under $63 to my door, but I'm pretty sure I don't want to pay that much. I was wondering if the cranks for that would fit the spindles on mine. It's a 22mm square spindle, but with NO taper. OR... If someone has this wide crank setup that they're not using, and is not using a tuned pipe, maybe we can trade or make some kind of deal?!?

I mistakenly welded the tuned chamber to the bottom of the steel crank support on one of my motorized bicycles way to far out to clear the rear tire..
The aluminim crank arm was really hitting the side of the chamber.
I found an old steel crank arm and used a torch to heat it up enough to bend it out of the way .
It looks weird but works fine.
Older three piece cranks used steel arms not aluminum like they do now.

Yeah I'm pretty sure my crank arms are aluminum, so bending them would be out of the question...
