Adds so much sound and grunt to my SQ5. This is how they should come from the factory. Not overly loud by any stretch, but you definitely know it's there.

(Read the last paragraph for a neutral compliment on the exhaust)

I don't know what I was thinking, David M. even says in his video that the exhaust is loud and I just figured he was adding a bit of creativity to his video. Man was I wrong....lol. The install went mostly fine, I think once we figured out the downpipe was slightly skewed from the centerline it went a lot better. I'd say the parts fit, they just need a bit of finessing here and there. Driving in Sport mode could possibly be annoying for some, but if you drive it into regular Drive mode the volume goes down.

In terms of the sound, I think the best explanation and complement comes from a friend of mine that owns two entirely custom Lambos (Spyder and a Perf) and a custom 700WHP Lotus: "HOLY $*** your car sounds good! And LOUD! The pops and bangs, especially when you shift are fricking glorious! It's aggressive as any Lambo with nearly the volume of my Lotus. Your shifts have the same aggressive pop/bang that a trans swapped Lamobo has, and theyre the best sounding shifts out there."

I was surprised with the quality of the exhaust. I was unsure I would like the way it made my SQ5 sound. But I’m in love with the way it sounds especially in sport mode. It sounds like a sports car and it’s not obnoxiously loud. It’s perfect! I definitely recommend and I’m looking forward to purchasing more mods for my vehicle.

Great experience from start to finish. First off, easy to order and fast shipping. Then received it well packaged, everything was packed with great care to ensure product integrity was intact. It was on overall easy install, and would recommend doing the downpipe at the same time if you got the money, but for me I did the exhaust only. Would definitely like to purchase the downpipe in the future, as their products are very well engineered, hence the name. One tip on the install of the driver side, you need to tilt the pipe and tighten to get it to clear the rear brace. Quality on the exhaust and welds are top notch, can't say enough about the quality. Recently purchased the intake and inlet as well and together a perfect symphony of sound. Really elevates the driving experience, and take it to another level. So do yourself a favor and pickup something, anything from Integrated Engineering. Everything they make is great, but exhaust is must!

If you're on the hunt for more turbo noise or a louder exhaust note than what your stock exhaust offers, look no further than the IE Catback for the Audi B9/B9.5 SQ5. Constructed from T304-L stainless steel, this exhaust system not only promises longevity, but it also eliminates the problematic single valve on the driver's side that often fails.

Designed to fit flawlessly onto the Audi B9/B9.5 SQ5 without any need for modifications, upgrading to the IE Catback is a hassle-free process. I can personally attest to this. The exhaust system delivers a deeper and more aggressive sound, lending a sporty and improved exhaust tone to my B9 SQ5. The turbo noises are also amplified depending on the turbo setup.

Installation of the exhaust system is relatively easy, and the high-quality construction ensures improved sound and enhanced performance. As an Audi enthusiast, I can confidently say that the IE Catback exhaust system is a worthy investment that delivers on its promises.
