Hi,
I recently just bought my first car and its a 2015 Leon FR and I love it. Ive looked into cosmetic mods and mostly gotten help on that aswell but I have no clue how to go about the exhaust. Im looking for a more deeper and a bit more louder sound but not too loud that my neighbours will hate me. Any recommendations, video links I could check to get a grasp on what im doing or what I should do?

Anything is appreciated thanks!

Extra:

I also found this induction kit one with foam and the other which is pleated, what is the difference and which one should I go for?

Check how many resonators (centre silencers) there and then get rid of em. If it still isnt loud enough you could do a back box removal or a different backbox altogether.
Removing them all will definitely be a lot louder than standard but removing the resonators makes it sound quite nice.

I always go for a pleated one. I had a foam filter once, and will never go back. They tend to desintegrate and I think the cotton filters do a better job than foam filters.

With regards to exhaust sound, I would advice either a cutout or a valved backbox. This gives you flexibility. I have a cutout on my Cupra ST and love it. I have a decat downpipe, stock center resonator, stock backboxes. The cutout is just before the Y-piece to the backboxes. I have it closed 90% of the time for normal day-to-day situations
