The two men are being held in Drogheda and Balbriggan Garda Stations.
Two men have been arrested in connection with the murder of Keane Mulready Woods.
The 17 year old was killed and his body dismembered last month as part of the ongoing Drogheda feud.
His partial remains were later found in a sports bag in Coolock in north Dublin and a burnt out car near Croke Park.
The teenager's funeral took place last Thursday and exactly a week on, Gardai made this significant breakthrough in their investigation.
The two men arrested this morning are being detained at Drogheda and Balbriggan Garda Stations, where they can be questioned for up to 7 days.
