Heading into Wednesday's game at the Chonburi Stadium as the only team with a 100% record despite the season being only two games old, the Twin Qilins were also looking to bounce back after a disappointing 4-1 loss to Urawa Red Diamonds in the AFC Champions League.
And just seven minutes in, they were handed the perfect opportunity to open the scoring when they were awarded a penalty after Jakkpan Pornsai was brought down inside the area; Mario Gjurovski stepping up and sending Sinthaweechai Hathairattanakool the wrong way with a clinical effort.
Two minutes before the half-hour mark, Phichitphong Choeichiu's neat pass picked out Teerasil Dangda, who sent a perfectly-weighted looping ball into the path of Gjurovski, who raced through before lifting the ball over the onrushing Sinthaweechai to double his and his side's lead, which ultimately proved enough for all three points.
Buriram United, Thailand's other Champions League representatives, remain unbeaten as well after beating Chainat 1-0 at the Thunder Castle Stadium, although they are two points behind Muangthong having drawn their opening game of the season.
Chilean striker Ramses Bustos scored the only goal of the game just before halftime when he made a darting run to the near post to meet a corner, before sending a glancing header past Kritsakorn Kerdpol to hand his side the win.
BEC Tero Sasana are up to second place following a 3-1 home victory over newly-promoted Pattaya United, who themselves dropped to second from bottom.
Japanese midfielder Sho Shimoji fired the Fire Dragons ahead in the 15th minute, before Spanish veteran Arzu made it 2-0 two minutes after the break.
Pattaya pulled one back in the 74th through an effort from Jung Ji-soo, but any hopes of a comeback were ended five minutes from time when Shimoji grabbed his second of the game.
Osotspa Saraburi are one of six teams yet to taste defeat this season after beating Bangkok United 3-1 at the Saraburi Stadium.
Following a goalless first half, the hosts took the lead on the hour mark when Bangkok's Brazilian defender Gilson Dias scored an own-goal, before Tangeni Shipahu doubled their lead just two minutes later.
Wittaya Madlam pulled one back for the visitors in the 71st minute but Ivorian midfielder Anthony Moura-Komenan struck six minutes later to wrap up the three points for Osotspa.
Bangkok Glass' woes continued as they played out a 2-2 draw at Chiangrai United, although the result was enough for both sides to grab their first point of the season.
Chiangrai took the lead in the 30th minute through Leandro Assumpcao, but the Glass Rabbits equalised a minute later through Thai international Chatree Chimtale.
Nonetheless, the hosts reclaimed the lead just before the break when Australian import Kyle Nix struck and looked headed for victory, until the second minutes of injury-time when Glass defender Peter Lang netted to earn his side a share of the spoils.
With both sides getting on the board, it is now Sisaket who are bottom of the pile following an emphatic 3-0 loss to Songkhla United, which came courtesy of Jules Baga's opener and a clinical brace from Seydou Kone.
Army United picked up their first points of 2013 after Chaiwat Nak-iem's 66th-minute effort helped them to a 1-0 home win over Ratchaburi, while Samut Songkhram held high-flying TOT to a 0-0 draw.
Finally, Police United were handed their first defeat after falling to a 2-0 loss to Suphanburi; Pichit Jaiboon opening the scoring from the spot in the 22nd minute, before Montenegrin midfielder Dragan Boskovic netted seven minutes from time to secure the win for visitors.
