Kirker 4-2-1 header trouble finding exhaust tip
« on: July 22, 2013, 10:37:25 AM »
Have an old, what I think is a kirker but may be a Mac 4-2-1 but I'm having trouble finding a good exhaust header. If you know of any that fit 2.5 inch opening and you think it will look good on my build let me know! Thanks!

Guys use cherry bombs, not as ghetto looking as it seems at first blush.

I just took a 2.5-4" megaphone and welded on a reverse cone cap for my bike, what is your skill set/toolbox?
