Our proprietary modular exhaust flange design allows this axle dump exhaust pipe to fit on both the GX550 and the LC250. (The included exhaust flange spacer is for GX550 only.)
This axle dump exhaust will increase the volume by 15-20% on the GX550 and about 5-10% on the LC250, while giving them both a slightly deep tone.
In our GX550 testings, the idle volume increased about 10 dB, and the top end volume increased about 15 dB. On the LC250, the volume increased about 5 dB during idle, and 7 dB at the top end.
