Exhaust piping size and valve control
What is the size of the piping I need to do OEM exhaust mod.
And to be clear, the 335is muffler, inside the muffler box the pipes are perforated correct? I want to put it straight pipe on the exhaust valve side. Also, anyone who sells remote control for the valve? I've seen 2 websites mentionned searching around but they are both non existant/out of business. |
