I bought a .40 LA off ebay and it came with a muffler that looks exactly like the OS Max E-3030, but doesn't have the "OS" emblem or "E-3030" stamped on it.  I took the muffler apart and the front part of the muffler is empty.  The back part has a plate where the front and rear of the muffler come together.  This back plate has a hole in the center about the diameter of the exhaust exit at the rear of the muffler.

Is this muffler a full equivalent of the E-3030, or should I order an E-3030 to replace it?

could by THREE just in case you break one !.

For %* sake , its justa muffla . The TOWER HOBBIES ones are LIGHTER . AND the Motor is REAL A.B.C.

Thanks, Matt.   Early this morning it occurred to me that the unmarked muffler might be from the Tower Hobbies .40.  Your response seems to confirm that the unmarked muffler was from a Tower .40. 

Just did a search of "Tower 40 muffler" and found a post by Tim Wescott in which he indicates his OS .46 LAs run the same on both mufflers.  When I asked about whether the two mufflers were equivalent, I was wanting to know if the motor would run the same on both mufflers.  Tim also indicated  that if he needs more nose weight he uses the E-3030 and the Tower Hobbies muffler if he needs less nose weight.
