1 piece muffler compatible with .21 and .28 engines.

This muffler features a 3-chamber design for a linear power band and exceptional all-around performance. A reinforced stinger and hard-anodized finish increase durability, while a single-piece pressure nipple is positioned for maximum body clearance and to lessen the chance of the pressure line being knocked off in crash.

The 2039 muffler is softer on the low end than the 2035, but is capable of more RPM and higher top speeds.
