I have a 2019 challenger scatpack widebody. I love the sound of the borla atak exhaust system. Does anyone know if it adds any horsepower and if it does how much? And any other recommendations for other nice sounding performance exhaust systems that add power as well?

The stock mufflers and resonators are pretty much wide open so not sure another system would add any more power.

I don't think the stock cat back exhaust is much of a restriction

I have the Borla ATAK on my A8 5.7. Cant say it adds any HP but in my opinion is the best sounding cat back out there (and I think the most expensive) Im def biased, but I get a TON of compliments on how it sounds and zero drone inside. That cold start in the garage puts a huge grin on my face every time. Zero regrets. If u want any HP gains from the exhaust, long tube headers will prob add 10 or 15 tops

Stock exhaust is designed by corsa, you are getting a bitchin mandrel bent system out of the box.


The catylitic’s will be the biggest restriction
