Muffler woes

Hello all, so since no one is really driving, the bike has become the go to for the few store trips I’ve needed to make. So when I parked the bike after my last run I noticed the right side muffler looked like it was tilted. I bent down to take a look and whattaya know, the weld is cracked clean off of the clamp. So today I decided to take the mufflers off. I wanted to measure the clamp size and what not to start shopping around. Well guess what, the left side was broken too!
So I took a short ride and it wasn’t as ridiculously loud as I expected it to be so I’m ok without the mufflers. So I’ve read plenty of times on here about HD sportser mufflers, are they all similar? Or is there a certain type? The other idea is just a pair of turnouts but I haven’t found any that looked like they’d work. And lastly I found these on eBay that look like they can be adjusted to fit, but not sure how’d they look with the heat shields.

Harley mufflers have too much baffle because they expect to see much higher flow. On a vn750 they choke the bike and you canít hear ANYTHING. I had mine on for exactly 4 hours and tossed them.

I still say the best setup is straight pipe to stock baffles.

Thanks for the info, I took a longer ride out on the interstate the other day and I have to be honest I kinda like the way the bike sounds without the mufflers. Which is a good thing considering they’re both broken. I was shocked when I looked up the price ($300 each) for OEM replacements. I’ll learn how to weld before I pay for that lol. Used on eBay is much cheaper but they look as bad as mine do. Any way, I found a couple of 3” x 6” long exhaust tips that’ll bolt on to the GB’s pipes once I get the corroded clamps and gaskets off. I’m hoping that’ll make it look more “finished”. I might need to mess with the heat shields to get it all to fit cleanly. They’re not very expensive and returnable if I don’t like it.

I'm in the middle of an engine rebuild, so funds are tight. However, when I have cash again, I plan to put a pair of these on in place of the mufflers.

The clamp on the front of these tips needs to be cut off, and a hanger should probably be added near the back.
However, the diameters should be just right to fit. And I think they'd look great on this bike!

I put these short 6” tips right on the GB. Makes it look like a solid pipe under the heat shield. A little more finished looking than just having the mufflers off. Like I mentioned in other posts I’m not looking to spend a ton of money on this bike anymore. They’re cheap as hell and I was able to get the heat shield clamp to fit right over them. They sound good to me, not ridiculously loud but grunty.
