Let’s be real: the stock exhaust on the B9 A4 is about as exciting as watching paint dry. If you’re looking to amp up that sound and really feel it in your gut, the iE B9 A4 Catback Exhaust System is where it’s at. This isn’t just about noise; it’s about giving your ride a voice that matches its performance. Say goodbye to that tinny, droning sound and hello to a deeper, more muscular growl that’ll turn heads.
One of the standout features here is the DroneTrap technology. Ever been cruising along, only to be annoyed by that irritating drone? Yeah, we’ve all been there. This system tackles those pesky sound waves, so you can enjoy the drive without the headache. Plus, we’ve paired this catback with our iE ProCore Downpipe, which is a game-changer. It comes equipped with a 4.75?? 200 CPI catalytic converter that’s got some serious tech going on. We’re talking rare metal coatings that help keep your emissions in check while still giving you that high flow you need for those upgraded tunes and bigger turbos. No check engine lights here, just pure driving pleasure.
This setup is not just about sound; it’s about performance too. It’s designed for the Audi B9 and B9.5 A4 models from 2017 to 2020, so you know it’s a perfect fit. Just a heads up: if you’re already rocking our iE B9 A4 Downpipe (PN: IEEXCK1), you’ll need to reach out to our customer service for a free adapter piece to make everything work seamlessly together.
In short, if you want to transform your A4 into a beast that sounds as good as it looks and performs, this exhaust system is the way to go. It’s got the power, the sound, and the quality to back it all up. Trust me, once you hear it, you won’t want to go back.
