So my megaphone exhaust sounds like it has broken the weld on the two little posts inside (see pic). It makes a terrible vibration noise at 1900 RPMs. I'm thinking this might be a good time to replace the exhaust. The car only has 23k miles. I've seen some reference to Corsa 2.5 inch as an option. I found this one on corvettemods -> https://www.corvettemods.com/C4-Corvett ... _9308.html
Anyone have any suggestions/recommendations?

My vote, remove and have the megaphone welded.

If you go with a new system, I'd be interested in buying the megaphone system for my '89. I'm moving to MD this summer and can pick it up from you!

I would fix the megaphones . Nothing sounds better then the spooling of the turbos.
