if I put a tower 46 muffler on a tt 46pro engine or take the baffle out of the tt muffler will I see a increase in hp

Yes, I put a Tower muffler on an OS 46 FX. With the same prop a 11x6 APC I had top open a little more on the high needel. It may have gained 400 rpm. Its makes a little more noise but sounds better.
