I'm not too familiar if this is what I need but I have Harris S/Os. If those midpipes will work with my cans and make them high mounted, I'll take them.
You might ended up destroying 4 midpipes if the angle, bending and the diameter doesn’t match. If I were you, I’d sell those Harris S/Os and add some cash on top (say you sold your S/Os for $300...and since you pretty much ready to spend $125, that’s $425 out of $6xx on a set of brand new high mount on eBay vs.... say you destroyed the midpipes x4 and sourcing another $300 slip on. That’s basically $300 slipons at hand + $125 (price for slipon only) + $300 (“new” slip-ons).
