Installed this on my B9 S4 and it gae it a great aggressive tone

Fits perfectly

I’ve had my FI catless downpipe for a few weeks now, and it’s been fantastic. No issues with fitment or quality, and the performance boost is exactly what I was looking for

After doing a lot of research, I decided to go with the Fiber Imprints catless downpipe for my Supra. The build quality is top-notch

Love how it sounds on my BMW M550i

Completely changed the look of my shift knob.

My M4 feels more responsive, and the aggressive exhaust tone is just what I was looking for.

sound is fantastic and the product quality is excellent

The throttle response is much sharper, and the car pulls harder throughout the RPM range

Perfect fit on my F82 M4! Not to mention easy to install! Gives the rear end a whole new look!

Highly recommend for any B58 owner looking to gain some power with a nice exhaust tone

The power delivery is smoother and more robust

fit perfectly and was easy to install

Good fitment

These mirror caps gave my 340 an aggressive look when paired with the smoked sequential mirror indicators. Definitely recommend
