Hackin the Mac, looking for feedback. was created by kzz1king
I am working on an exhaust. I had originally planned on a stubby muffler right below the motor but can't find anything small enough. So I decided to cut up this header. I shortened the headpipe to it by 4" and am thinking of taking some off the can too. I will then remove the mount and weld a new one in below the brake peddle. What do you think? Stock length, short or shorter? See anything that might be a problem. Thanks

No problem, I hacked off about 8 inches on a café bike I built. Did not effect performance at all.

It's a Mac for God's sake, not a Moriwaki! Cut it up! :evil:
Don't be ridiculous! It's only a flesh wound!

It is cut up already! Just have not decided how much to cut off the can. Cut it twice and it is still too short :laugh:
