The 2020 Z4 is BMW'slatest incarnation of the Z4, keeping its reputation alive and well as a powerful and fun roadster. The Z4 M40i dramatically benefits, in terms of sports car sound and power, from a Fabspeed Motorsport Sport Cat Downpipe. You'll appreciate the more aggressive exhaust note and significant horsepower increase.

These downpipes feature German made HJS 200 cell EURO 6 EC certified compliant trimetallic catalytic converters. We use 4 inch piping from the engine side to the cat, and 3 inch tubing from the cat to the rest of the exhaust. These are the largest and highest flowing catalytic converters you can fit on the M40i 3.0L. Larger catalytic converters are better because they allow for more exhaust flow and the increased catalysts surface area allows for better exhaust gas filtering which means emissions compliance and will NOT trigger a check engine light. Our Sport Cat Downpipes are a direct bolt-on replacement for the factory Supra catalytic converter.

When we looked at the factory 12” long 700 cell ceramic core cats we immediately found an opportunity for improvement. The OEM Cats restrict exhaust CFM flow, limit sound and worst of all, rob performance. Replacing the OEM cats for a set of Fabspeed Sport Catalytic converter will net you improved performance with absolutely zero fear of a check engine light.

FEATURES:

  • Simple bolt-on installation. Instructions included below
  • The largest HJS tri-metallic catalytic converter that will fit in the factory location
  • This HJS catalytic converter will support 1200HP+
  • Designed to fit Left hand drive and Right hand drive cars worldwide
  • Significant performance gains across the RPM band. Estimated +35HP gained over the factory unit
  • Even more power can be unleashed with a ECU tune. Please inquire
  • No tune required
  • Superior quality all German and USA components built in house by hand
  • Optimized for maximum performance with NO catalyst generated check engine light, guaranteed
  • TIG welded by our expert welders
  • T304 stainless steel construction
  • Fabspeed performance products are backed by Fabspeed's Lifetime Warranty

Why We Choose HJS Catalytic Converters:

HJS German imported catalytic converters are made from some of the highest grade materials you can find in a catalytic converter. This yields high performance gains and longevity so it wont deteriorate over time like lower grade catalytic converters. These catalytic converters flow up to 93-95% of a straight pipe in most applications. The benefit is that you get the "straight pipe sound" while still being able to provide enough emissions scrubbing to prevent a check engine light. If you'd like to learn more, watch our video about HJS catalytic converters.

Kia phone holder, it’s worth it if you go buy some heavy duty tape!
Model: 2014-2018 Forte
If you’re going to buy this phone holder, you better get some Strong tape because when I put it in my car, the tape didn’t stick at all. I bought some clear thicker tape that is used for patching the liner in a pool, it’s waterproof and works in hot or cold temperatures and now the phone holder is in place and will not move and now works beautifully!

Strength
Model: 2019-2024 Forte
It does fit perfectly in my dash. I do wish that there was a was way to tighten the fit to the dash but other than that it does its job of holding my phone.

Only lasted a couple of weeks.
Model: 2014-2018 Forte
Was nice but after the first day, it would start to loosen and my phone would slide down. After a couple of weeks, it fell off from the car completely. It was a birthday gift so pretty disappointed.

Will not stay attached
Model: 2014-2018 Forte
I used rubbing alcohol to help it say attached. Unfortunately would not stay attached so useless. I thought of getting Velcro or some other type of product to secure it, but why should I have to work at getting it to work? I was never able to see how my phone would work as it never stayed attached
