Bolt on more power with an Egan Performance “header pipe" to your Echo 355 chainsaw for an immediate increase in power and throttle response and a reduction of engine temperatures. Independent dyno sheets show an increase of 10% in horsepower. Note: 2 mounting bolts (torx) are provided as the oem bolts will no longer work. We recommend using loctite when installing. The header pipe will get hot and can cause burns if it contacts your skin or clothing. We will not assume liability for misuse or negligence. The header pipe does not include a spark arrestor. Made in the USA from mild steel. Upon installation, the carb will need retuned. NOTE:  The site will automatically calculate Priority Mail Flat Rate for shipping during checkout.  When you only order this item, and no other products, we will send your 355 pipe to you via First Class Mail (with tracking) when doing so will result in significant savings in the cost of shipping.  We will refund you the difference when that occurs.
