Just what I expected, have the flexibility of disabling the device via the Bluetooth App. Noticeable difference!! Very happy!

Best in the business for cold air intakes that don’t require a tune

After doing research stillen gave the most dyno proven HP gains. So lead to me choosing them over other competitors. Have to say one of the easiest intake installs I’ve done!
After installation didn’t notice much on the sound(didn’t really test before). But the throttle response when driving is dramatically improved and nice. Can be a little jumpy but when proven HP gains it shows!

i have smashed this thing into walls repeatedly and been tboned by an suv totalling the car and it still looks perfect and fits great after pullijg the frame back out.

Got this kit installed in a little under 2 hours, thanks to the youtube.

Noticed immediate and instant gains on the low end. Fuel mileage is still TBD, but the gain in the low end was worth it. Highly recommend!

Fit perfect on a 2024 sierra. Looks awesome

Immediately felt the power difference and I was able to do longer burn outs with my truck lol. From the line it’s quick and accelerates whole lot quicker than usual

The sound is incredible. It’s quiet while idling, but nice and deep when cold starting or accelerating. Perfect for us old heads that still love the q50, but don’t want to annoy are neighbors. Not obnoxious are too loud. Stillen nailed it with this exhaust upgrade. It sounds great passing through canyons. If your car is lowered like mine, the sound feels deep and powerful. Perfect for daily driving your Q.

Fairly quite below 1.7k rpm with a low tone rumble but you could really start to hear it above 3k or if you step on the gas. I have an hour commute and it is not too loud for it to be an annoyance. Welds all look very good. Parts fit together well. I put rustoleum high heat primer and spray paint to hopefully avoid corrosion for a few extra years. Very happy with the purchase for the price.

These look great, much better than the Ti tips. Much better finish with the double wall look. The included clamps were a better finish than the clamps included with the Ti tips, but was curious why they went with the smaller diameter fastener. Looks good with the rear valance.

I’ve been running the tuner for a week now and have driven just over 1500 miles. Very happy!

Just as advertised fits perrect and is so much better to drive on than the OEM sway bar. Tons less body roll and i upgraded all the suspension along with it and its feels so tight and so nice able to corner at crazy speeds

Love the look and great material quality like oem parts

Easy install ! Perfect fitment ! Sound just right ! Not too loud but perfect for street use , amazing finish on mufflers ! Fast ship as well !

Definitely noticeable throttle response. Hole alignment issues have been rectified.
