As far as exhaust?
Yours is good.
The only thing better is long tubes with high flow cats.
If you do that then your next step will be a supercharger. Don't get all worried about exhaust.
There's a whole lot of changes before the exhaust that will need to be done to take full advantage of it.
Peace!
