Short answer. No. Procedure in the Municipal Trial Courts generally follows the Regional Trial Courts, but the rule expressly excepts civil cases governed by the Rule on Summary Procedure from that uniform approach — those cases follow their own distinct set of rules instead of the ordinary ones.
What the law says
The procedure in the Municipal Trial Courts shall be the same as in the Regional Trial Courts, except (a) where a particular provision expressly or impliedly applies only to either of said courts, or (b) in civil cases governed by the Rule on Summary Procedure

The general baseline for Municipal Trial Courts
The default rule states that the procedure in the Municipal Trial Courts shall be the same as in the Regional Trial Courts. That uniformity is the starting assumption — a Municipal Trial Court case generally follows the same procedural rules a Regional Trial Court case would, rather than an entirely separate procedural framework built just for the lower court. That baseline binds trial courts and litigants alike, unless one of the two named exceptions genuinely applies to the specific case actually in front of them.
Summary Procedure is one of two named exceptions
That baseline gives way in two situations. The first is where a particular provision, expressly or by implication, applies only to one of the two courts. The second is specifically civil cases governed by the Rule on Summary Procedure. Your question falls into this second, expressly named exception — summary procedure cases are carved out of the uniform approach entirely, not merely adjusted at the margins.
Why summary procedure is treated as its own track
Summary Procedure exists as a distinct set of rules precisely because certain kinds of civil cases in the Municipal Trial Courts are meant to move faster and more simply than the ordinary rules of procedure allow. Rather than trying to layer that speed and simplicity onto the same procedure used for Regional Trial Court cases, the provision recognizes it as governed by its own separate rule altogether.
What this means for your case
If your case is one governed by the Rule on Summary Procedure, you should not assume the ordinary Municipal Trial Court procedure — the one that mirrors Regional Trial Court practice — applies to it. The rule you actually need to consult is the Rule on Summary Procedure itself, not the general procedural rules that would otherwise govern an ordinary case in the same court, since the two separate sets of rules can differ meaningfully on timelines and on which motions are even available.
