Safe to say there's no way to get the performance of an aftermarket downpipe, without the added noise level?
If you are thinking about going with catless downpipe, I have barely used ar design catless downpipe with integrated vibrant resonators in it. This may be suitable for you as it gives you same power gain as catless downpipe but with reduced drone and noise.
If interested, check my sales post.
As long as you have secondary cats in place, you won't smell much gas after cats get warm.
