ain't so much as lack of back pressure that burns the piston as it is running lean that does it

I'd start with keeping the stock exhaust but replacing the goats belly with a crossover pipe. This will make the bike louder, but you won't lose as much overall performance as just running unconnected pipes.
Losing "back pressure" won't hurt your pistons, but you might need to rejet if you go to straight pipes...you'll gain better power at or near redline, but you'll lose power and torque at middle rpm ranges.
Many think the "goats belly" is some kind of EPA thing....but Kawasaki's own description calls it a "powrer chamber"... it is actually designed to provide the best power over the entire RPM range.
If you just want the bike to be louder....drill the baffles.

Custom Straight Pipes
Hello all, first I want to start my first post with a big thank you for all the information that has been shared on this forum. I have been lurking for awhile and it has helped me tremendously with my first bike. It is a 2004 Vulcan 750 that I got 2 months ago with 16,000 miles, I'm up to 17,500 now!
So like most of you I want add some more sound to the motorcycle but can't shell out the $400 for some Vance and Hines. I was thinking of taking off the mufflers and goat's belly and fabricating a cross over for the left side to the right. Is there an advantage of making both of the pipes the same length vs fabricating an H pipe? I have read that I could fry my pistons by running the bike without a muffler to create back pressure, is that true? If this has been covered in another post and I passed it up I'm sorry I just couldn't seem to find any info covering it already.
Thank you again for all of your help!
