Best performance exhaust

[410.Stinger]

So I’m currently running the mbrp exhaust but I heard that the stillen exhaust adds more HP and TQ. Not really looking for a better sound but just gains. Is there anything better than the stillen exhaust?

I've never seen a real attempt at comparing power gains with exhausts for the 3.3 Stinger. It would be nice if at least some existed. Same for intakes.

They all have almost zero performance real life gain. The gain you saw on the dyno is simply from turbo overspin due to back pressure change and our ECU is okay with it. For Audis I've even seen ECU dial the torque back to make the car run less power due to turbo spin limiters.


If you dail the stock car's boost curve as same as the moded one it will make exactly same amount of power.

@410.Stinger you seem like a horsepower junkie like me. Ark Performance or Stillen are going to be the most performance-focused exhausts that we offer at the K8 Stinger Store. To really see these gains, pair the catback with a high-flow primary and catless secondary. I highly recommend the Ultimate Performance HFC Downpipe and Midpipe Combo Kit and I can help you out with a discount on that. Just finish this all off with a tune like the JB4 and you should see some good numbers! I hope this helps, feel free to send me a message if you have any questions!
