Coated sidepipes still get hot, but do cool down faster. The sidepipe heat shield, sitting just 1/4" away from the muffler I can hold my hand on with the engine running. The top is warm, the sides are cool.
With a 30" muffler, the shield is 40" x 7" perforated steel sheet. Stainless is not used as it retains, rather than rejects heat as the coated piece does, and the coating provides corrosion resistance.
The shield is rolled into a 4 1/2" dia semicircle (prior to coating), small brackets are installed on each end, then fastened in place with stainless hose clamps on the inlet and outlet 3" sections.
Simple, not particularly expensive, durable, looks factory, and most importantly no leg burns or melted clothing.
Build a couple of sets, and see what happens.
