The Hard Rock x Gumball 2026 Exhaust Tee in Black leads with a back design of red checkered flags rising from a cloud of exhaust-style smoke. Hard Rock x Gumball 3000 runs across the shoulders, with a small HR x GB3000 mark on the front chest. The rally-inspired details tie the tee to the Gumball 3000 collaboration and the fast-moving feel of the road event. Add it to your collection before the next run.
