AA X-pipe catless

So I just changed my AA HFC to AA catless. Easy swap. Already I love the new sound (bit more deep, then screeching at high rpm!). The throttle feels, lighter, but I think thats because the car is still readjusting.

I changed it just so I could know what it sounded, smelled, felt, and how much more power (if any) it would produce. Smell so far isn't bad, but I still think the car needs to adapt more.

So far so good though! New updates, as well as dyno will be posted in this thread later one. That dyno will also have my previous result because I lost the paper with the afe intake dyno on it :/ I am still using the AFE intake because I believe it still makes power in a real world setting. Heres the other thread:

The AA is one of the best in regards to being able to change from cats to catless which I really like. My guess is that you'll be happy.

I did the same on mine and ended up catless. More power that can be felt, better sound. A winner if you ask me.

I already love it. Definitely very very little to no drone during freeway cruising. The hfc was notorious for the drone. Can't tell if no drone is good or bad haha. Love the sound!
