It was considered but after several thousand miles - no problems though I have heat shields on the mufflers. I felt that heat would be better dissipated without any restrictions. A hand feel of the booster and MC show them to be just above ambient after a hard drive. Low mass of tail pipe thickness tubing, no cats, just wont retain heat more then a very few minutes
