How can I make my 201tc more powerful (without porting it)

Not noticed that myself Matty.  I have 3 ms200t’s.  Some properly ported by Spud and another with a 11mm hole drilled in the muffler.

 

All three were noticeably more powerful than a stock saw and exhaust.

Aye but they are ported too so you get the benefit.. my feeling was when they started getting cracks in the exhaust they lost a lot of torque, sounded and picked up great though… if you liked hearing damage.

One was a full port and exhaust mod.

 

the other was just an exhaust mod.

 

Thenother had an exhaust mod but I sold it years ago.

 

The last one I own is for spares or repair.  Not a lot left of it tbh.  It is like a box of fresh air at the moment LOl.

The MS200 benefits from a muffler mod but doesn't like any ignition advance.

I stopped drilling holes in MS201 mufflers a long time ago and just opened up the outlet hole with a dremel....much neater job but same effect.

TBH, I never bothered "Porting" MS201Ts as they responded so well to a bit of muffler and flywheel work and a change of air filter.

Before anyone says anything...I charged a much lower cost for MS201t modification and stated the work done on the invoice

Could you add some photos of how to do the work on the ms201t

It won’t make it more powerful but will cut a lot quicker if you switch to 1/4” bar and chain

Sorry, I really don't have the time but a previous post in this thread lists how to do the ignition advance and opening up a hole with a dremel isn't that difficult or technical TBH!

I’m not telling you to do this but I drilled two 6mm holes in my 150 exhaust and it’s a different machine. Picks up the revs a lot quicker and never bogs down, even with the whole 12” bar buried.

Aim to make the hole about twice the original size. If you can sneak under the deflector and enlarge the hole that's great, I chose to drill down through both, shape the slot and then cap the deflector as I don't have a Dremel. Useful increase in power for not much hassle and low risk of problems.

 

I think if your saw is 2016 it's probably tcm so will autotune to compensate. Do you have carb adjusting screws?
