Description
Stock exhaust systems leave performance on the table—both in weight and power output. The Straightline Performance Exhaust Silencer delivers a measurable weight reduction, potential horsepower gains, and refined exhaust tone without sacrificing the acoustics your neighbors will appreciate. For Arctic Cat Blast LT 4000 owners looking to optimize sled performance with a straightforward bolt-on upgrade, this is a no-compromise solution.
This silencer leverages ceramic coating technology to manage heat effectively while maintaining stock fitment, meaning installation requires no fabrication or custom exhaust work. The weight savings alone—5-7 lbs. on the standard version, up to 14 lbs. on the stainless option—translates to improved acceleration and handling, particularly noticeable in tight trail conditions.
