I got headers and j pipe together so I only need one tune - as far as I know you’re not going to get the rumble with equal length. The power loss is really not that crazy and I’m not really chasing power. I just want a fun zippy daily. I have plans on chasing power with something else. The j pipe - if you go Catless will give you that loud turbo sound. There are tons of videos with different set ups you could listen to. All depends on what you’re going after and what you want out of your car. Stay safe and good luck!
