N63 catless downpipes

I recently took off my catless downpipes because I couldn't stand the gas smell and my neighbors complained about the cold start but I definitely missed the power and turbo. Any recommendations on how to get around this issue even with less hp but still want that aggressive deep sound of the engine?

You can try a catted dp and install a pair of Vibrant resonators to tame the sound even more more if necessary.

Yeah that video of that 535 is loud but with the v8, it's even louder

But do you think I'll still have the power after installing catted dp?

I cant speak cuz I dont have a dp but from what AR said you wont compromise too much performance with their hi-flow catted downpipes. You should ask them directly so you can make an informed decision.
