Catless or resonators delete....?

Dear members hope to get some help from you...I am about to made up my mind for a new exhaust, I have listen to youtube videos for several months now, nearly going crazy, there are so many good options.....I have landed on the Eisenmann Sport (I will not go with Race!) and then I cant decide between going catless DP or res delete, I will not do both to begin with...witch set up would give the best sound/loudness in your mind, thanks for feedback.

Go with the Eisenmann Sport, catless DP and code out the ASD. You'll love the sound and appreciate the exhaust.

You can always have cats added to the midpipes if you are worried about the smell. Just swap out the resonators for them.

Did you mean like 300 cell high flow sport cats..? If yes, will they fit were the resonators have been or do you need some extra piping to fit the rest of the OEM piping...?

Is it the product on the left...?

Either or. Can be stock midpipes or aftermarket. You buy some cats and have a shop do the work. Depending on the shop they might be able to get you the cats as well. Just make sure you find a quality shop and you use quality cats. Don't want junk welds or cats that barely work.
