With the straight back system we really like these as they simplify exhaust routing so there is no need to run exhaust shields or worry about burning through engine blankets. They can be quite loud but can be toned down with a quiet core insert which we also have available.
Back country-Direct straight back system with a 12in silencer, perfect for snowbike or dune riding. massive increase in top end power.
Note-This system does not include oxygen sensor bung.
