4-1 options

All, I'll preface by saying I've done a brief search and I'm also on the mobile so bear with me. I have a 77 kz650b that Po decided would sound better with open heads, its far too loud for my taste. I would like a motogp/Yoshi style exhaust. Right now I can't afford a brand new exhaust, are there any that can be modified to fit. Thanks Josh

Find some used stock pipes and install, or find a used 4 into 1 and put it on.....
Not sure what would be need modified
Or all you really need is 2 mufflers sections used or aftermarket.....

Shout out to martin_csr for the tip on years. Went with an eBay zr7 chopped down. Still a little loud for my tastes but the bikes running much better. Now for a baffle and a tune up. Trying to figure out how to post pictures from a cell phone.
