Installed fall 2024 and love this exhaust so much! At idle its slightly louder than stock, but as you accelerate and hit higher rpms is when it really shines! Noise inside isn't too loud so days I want to enjoy it I'll roll my driver window down. Planning on getting the long catted downpipe down the road and maybe a cst4 turbo to pair. Love all of the products I've got from you guys so far, great work!

I love the tone of the exhaust and with the downpipe. Most definitely a must have, sucks that when I bought mine the price dropped. I definitely would recommend this Catback exhaust.

Will your 80 mm downpipe fit this if I decided to get it down the road?

I'm looking at getting this system and I'm wanting to put this onto the stock mid pipe, will this work? Looking at getting a race pipe later on

Would this cat back exhaust for a 2009 Mazdaspeed 3 fit to or be of suitable tuning for a 2009 Mazda 3 Hatchback? I’m looking for a cat back exhaust system for this car but it looks like the one listed for it is a full system.
