Used some scrap sheet aluminum that a friend gave me (from some aftermarket undercarriage plates from a 350Z or G35 I think) to fabricate an exhaust shield for my Yakima Exo. As luck would have it the Exo lines up pretty much right behind the passenger side exhaust. There's a rubber-coated part and some wiring right there at the end (just tucked inside) that I think needed a bit of heat protection. I've seen a few threads elsewhere of folks that have melted rubber/plastic parts when their hitch accessory was right in line with the exhaust.
Just got it cut, trimmed, bent, and tapped for a mock-up today. I'll be attaching it to the exo with some worm clamps for a test drive around to see how it affects temps on the Exo parts. Then, I'll get it sanded, smoothed, and painted gloss black to match the Exo. Then tap the Exo to attach it with 4 shorty 10mm bolts.
Set up so that the gate swings open with full clearance of the shield.
