Tomos A35 BiTurbo Pipe on the Iowa Urban Express

Hack ‘n’ weld BiTurbo on the Iowa Urban Express.

After adding an SHA carb and getting the right jet in, this thing hauled ass! It also helped that I raised the exhaust port slightly – maybe a couple millimeters and opened up the exhaust port in general. I later added a monster air box which slowed me down but I may switch back. The biturbo is relatively quiet which is great. I got lucky with the header length as well. There’s a formula on youtube that I’ll link to later.
