🚗 Flowmaster 842543 2.5 Inch Inlet/Outlet Delta 40 409s Performance Muffler Review

Not too loud and not at all. I think it ended up being a good compromise. You can tell it's not a standard muffler, but it's not annoying like some of the louder ones I've heard. I decided to only do a muffler replacement, not an exhaust overhaul.

I bought two of these mufflers for the C6 project. Perfectly welded, they sound nice and even. I buzzed a bit at 1900-2200 rpm. I had two more projects in the works and would buy these mufflers for those projects.

I bought these to replace the Flowmaster 40 Thunder Road mufflers I had because of the rumble in the car. This is a Deltaflow, which is supposed to be quieter in the car. They are worse than the drone that has just been changed in the speed range. $200 for mufflers and $200 to cut out old ones and replace with these. What is too much noise now. Certainly a little misleading advertising. I would appreciate some sort of compensation, I feel like I've been misled
