Is there a company that has a tuner for the 2016 Honda Accord Sport 4cyl? Also anyone know the exhaust diameter of the pipe coming right off the catalytic converter? We may want to add a cutout there. Thanks

 

I doubt you will find a "tune" for these, if there is a claim of one I would be very scared of it.

If you are wanting noise, there are aftermarket mufflers that you could look into.....not sure what you are going after with the "cut out"?

 

He is looking at this new design. cuthroatcutout.com It should give it excellent flow and sound and if need be, he can always return it back to stock. I like the idea that because the catalytic converter is quieting down the exhaust anyway it won't be crazy loud and will still flow better than any cat back. To bad about a tuner. You would think their would be a market for it since there are a lot of Hondas out there...
