Exhaust info

[1973]

Hi all,
Can you use a straight through exhaust?
Will it effect it as in back pressure?
How could you make the sound deeper?

ya you can-2 or 4 stroke you asked about back presser so I'm guessing 2 stroke-go with a bigger then stock tube go long for bottom end short for top end power cut it back 1/2in. at a time entell you get what you're looking for-if you're looking for power get an expansion chamber and tune it the same way long to short head pipe before the expansion chamber have fun!
