It is indeed a huge pain in the ass to chop out exhaust components behind anything at all. Cutting tools are all speed and no torque. If you use stainless or something it will really piss them off. Aluminum will deform, frustrating cutting attempts. Mesh will block access just as easily, maybe go for a stainless mesh so its really annoying to cut through and bank the weight reduction/cooling benefits. If you use a grinder, the abrasion will take a lot longer as you have to clear both spots where you would like to cut. If you use a sawzall aka reciprocating saw, the blade has to have totally clear movements or else it will flex and slow down. If you use a torch it goes quicker, but the set up and hauling the tanks is not easy, torches are fiddly, especially if not properly maintained, the smoke is poison, and theres fuel lines down there to boot. Unpleasant. They'll just curse and roll onto the next mark.
