Default Squeaking from B&B Bullets

I bought a 2014 with B&B Bullets. About 75% of the time there is an overwhelming squeaking noise coming from the rear. Even the longtubes aren't enough to drown it out. I believe it's the exhaust because the rare times it isn't squeaking you can make a faint squeaking sound by manually moving the exhaust around.

I'm trying to diagnose before taking it into the shop. It even happens while parked in neutral although not as bad. I would guess it just needs new exhaust hangers and a good shot of silicone. Does this exhaust have any moving parts inside that could be causing it?

Do you have the NPP version with the valves in the tips? I would make sure everything is all torqued and maybe lube the exhaust hangers a bit. Hopefully it is not the valves squeaking.

I'm not sure which model but I don't see any valves when I look into the tips.

Start by getting underneath and tighten all the clamps. That should take car of your problem.

+1. I have a Bullet and no squeaking noises whatsoever. On a previous car however I had some minor rubbing and had to adjust the position of the exhaust.

Tighten all clamps and lubricate all hangers.

The piece of metal connecting both mufflers together ended up being the cause. You can see it start to separate in the pic when you pull the mufflers apart.

That stinks. Can they fix the weld without having to remove anything?

I took it to an exhaust shop today and it was a pretty quick fix. Hopefully the weld holds.
