Any recommendations for an exhaust replacement with or without catalytic converter that might increase horsepower?

You're not going to get much if any HP bump with exhaust unless there something wrong with your current.one on an S4. It's pretty free flowing. Ths manifold is quite good and everything behind it isn't bad. Might be worthwhile to replace the cat with a high flow model. If you still have the original cat on there its possible it's a bit plugged up. Don't expect anything radical though.
