One pipe was a couple inches too long, and I don't own fancy cutting tools, so I had to hand saw it multiple times to get proper fitment. Also, the 2.5" T-bolt clamps are extremely snug on the silicone couplers even at their loosest setting, so that was a pain. The larger clamps left ample space and were a breeze to work with. The pipes do look great now that they're installed, but I dread ever having to take them off and on again. In hindsight, I wish I'd gone with full silicone hoses instead.
