Bolt on more power with an Egan Performance “header pipe" to your Husqvarna 550 mk2 chainsaw for an immediate increase in power and throttle response and a reduction of engine temperatures. This pipe will only fit the mk2 version, and not the older version 550s.
Independent dyno sheets show an increase of 6% in horsepower and maintaining more power throughout the rpm range. Please check out the dyno sheet below.
We recommend using orange loctite when install this pipe. 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 as one will not last in this application.
All mounting hardware is included. Please take care with the muffler gasket when removing the oem muffler. We do not supply replacement gaskets if the old ones are unusable.
Upon installation, the carb will retune itself.
Please Note: This is considered a 'larger' item. Only two 'larger' items can ship in our standard package. If you order more than 2 of these types of items, or other items in addition to them, there will be additional shipping charges, which you will be emailed an invoice for. (This note is in the product description of all of our larger items.)
Made in the USA from stainless steel.
Fit and finish is very nice. Welds look good. Could feel a noticeable difference in throttle response and power. It polishes up nice too. Hear protection is a must after install!
Just got done running this pipe for the first time in some decent size oak. I previously did my own muffler mod and this is a big upgrade. Feels better in the cut and has more torque and hold rpm’s better. Easy install. I have 3 point dogs and it does fit but rubs the inside dog slightly. High quality pipe built to last and sounds mean! Loud so keep that in mind. Great company to buy from.
