Hi there have not received muffler yet cheers . Graeme

Fit correctly improved power great performance

No bs. The amount of power you get from this muffler alone is incredible sure it might be a bit loud but it does it’s job very well.

Love it guys 💪

Definitely wakes the saw up and sounds great as well. Neighbors probably hate me now but oh well

Pair this muffler cover with Max Flow filter setup and def gives the 661 some pep and chews through bigger wood nicely.

Easy to install, much better than the factory seal on the filter.

I’m a professional forest products harvester and I have to say I’m extremely impressed with the design and material used for this product, it really holds up and opened up my ms661c potential after a quick re-tune the top end was night and day difference. The only thing I notice about this material is it tends to hold the heat longer than the traditional muffler but it’s still a great trade off! I will be doing a formal review on my tik tok , as well as YouTube “New England logger” that’s again!

Legit bolt on boost. Well made, easy to install, and immediate gains, even on my ported 2511 which was already sporting a pretty heavily modified muffler.

If you don't have one you should.

This pipe woke up my saw and it ran great without tuning

Very well made, sounds good, very crisp throttle response when paired with max airflow kit

Haven't installed my muffler yet! Looks quality! Shipping was fast stayed local! Support local and you will get quality, this weekend I will take videos of stock and then straight shot, I can't wait!
