I managed to get a pair of new old stock cobra mufflers for my newly acquired en500a. Unfortunately, to install, I have to cut the original pipes just in front of the crossover which I won't do until I get a spare set of pipes to screw up instead. At least then I'll be able to go back to stock.
My question is: if I install the cobra mufflers, is rejetting the carb necessary?
I tried the cobra website for info but these pipes are legacy items that aren't made/supported anymore.
Any help/suggestions would be appreciated.
