i Just Went With The Pipe That Was In Stock Here, Of What I Have Read, There Is Not That Much Differences Between Those 2. I Haven't Tried It Yet Without The Silencer Though.
In Reality The Thing That Happened Was As Follow... Had Broken A Head Bolt On The 29cc, So The Head Gaasket Was Scrapped. Change It, A Replace With A New Bolt, The Cylinder And Piston Seem Alright Then, When Was Get A Little Hot About 2 Min Running, It Used To Stall On Me. Took Everthing Apart, To Find Out That The Piston And Cylinder Was Scratched. And When This Happened It Caused Vibration That Made The Redcat Tune Pipe To Brake. So We Changed Every Thing. That Is How I Got This Pipe Lollol.
