I chose DMH units based on both reviews and close inspection of build.

I have had mine for many years without a single issue. Given the need again, I would choose them again.

That said, I do believe that the installation is key to success.

Choose a reputable installer that has experience with Corvette's, experience with cutouts and works on EXPENSIVE cars. Large "metro" areas always have "the shop" to go to. Drop by their shop, talk your deal and rely on experience.

Good luck

I did a bypass on my Corsa added 10 db

Used Pep Boys 3" cutouts made for easy overlaps













Added some angle iron guarding to the wiring

It looks like a bypass mod with the ability to turn off or on.
I did this with stock exhaust but no cut out.

Also I thought the purpose of cut out would be to dump after headers?

It is, but sometimes finding a shop that will weld before the cats can be a difficult task.

The purpose is to make more noise

Dumping under the middle of the car was too violent for me.

This gives me 10 db more volume without smell and vibration

Nice setup. I'll be doing something like that on my car, but using the factory mufflers instead.

I agree that dumping under the car is too violent. The sound is great at WOT but the drone and vibration makes it really unpleasant.

I got them done near you at what used to be Extreme Automotive on Stage. It has been sold but I hear they still do good work.

Good luck, maybe see you soon.
