EganPerformanceSaws

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.

Cracking piece of kit , lovely welds . Good postage . My 550 will Rip !!!

Quick shipping and quality parts

Great exhaust and dogs! I’ll be ordering more for my other saws soon!

This is my 5th or 6th EPS mod. Hands down, the best. Added it to my Dad’s last saw, an old 036 Pro to get it back in action as a limbing saw for my small operation. Pretty impressed with how it has really added some low end snap to that little saw.

My vmodest is running like a champ

Make sure you’re wearing ear protection because this thing is a screamer. So far it seems to be more stable than I had thought. Pumped on the product.

Another awesome upgrade from Egan Performance. Perfect fit, great sound and definite performance increase. Shipped out quickly. Thanks!
