I put this on and my saw came to life. Had to do a little tuning but nothing major. If you are on the fence about getting one, well jump over and get it, You won't be disappointed.
Looks great and sounds great. Haven't put it in wood yet but seems responsive.
Good fit, good sound. Seems to add some rpm’s when hard cutting.
Definitly a bit more rpm this is the best filter design there is wish all saws came like it
Egan straight shot is the best exhaust I’ve used!! Awesome sound with excellent performance!! Thanks for a bad a$$ bolt on part!!!!
Thank you for the great service. I put the straight shot on just about all my Stihl saw. Always happy with results.
Dawgs are a great aesthetic and the exhaust really makes it sound like a professional saw thanks very much
5 min performance upgrade. You do need to retune after install but the cost of this upgrade is worth it. Buried a 36” bar in hard maple after install and couldn’t make the saw feel it. Unbelievably easy upgrade.
Love these dawgs, work very well on the 661. Thank you! 5 stars!
This thing kicks @$$. Highly recommended for 661
Great upgrade for 661. Very nice system. Thank you
Definitely a nice upgrade. The performance of the saw with the EPS exhaust is well worth the money. Great throttle response and man she has some serious crack to the sound. Definitely want some hearing protection while using this product.
Sounds great!
Dogs fit perfectly and make it preform great in sticking saw to tree for cutting.
The air filter doesn’t disappoint, fits like a custom hand fitted part, air filter itself is of great quality and saw seems to react well to increased air flow. Great product.
