Berk race vs Berk street review

I've had the Berk race w Berk mids and ar catless dp on my car for a while and swapped it to the street version recently. Highway noise is reduced significantly but I notice a substantial difference in turbo response and power with the street version.

Looking for a way to mod the race version to have a muffler.

The race clearly has more flow and less back pressure and is much better imo.

Just a heads up for those thinking about either version
