Thermal R&D 5408A Universal Exhaust Tip 5in Dia x 8in Long x 4in Inlet Polished Angle Cut
The Thermal R&D 5408A is a polished dual-wall angle cut exhaust tip measuring 5 inches in outer diameter, 8 inches in overall length, with a 4-inch inlet.

Built in Lancaster, California, USA, the 5408A uses the same premium stainless dual-wall construction as the full Thermal R&D exhaust tip lineup, delivering a bright polished exterior that resists heat discoloration from the inner wall buffer.
