PRODUCT DETAILS

Punchier Turbo Sound & Serious Pulls for Your BMW B58

Dial up your turbo whistle and feel that instant power surge with the BMW B58 Catless Downpipes 4.5″, made for M240i, 340i, 440i, 540i, 740i, and 840i from 2016 to 2022. Whether you’re lining up for rolling runs or just want your exhaust to snap necks in the parking lot, this upgraded downpipe is the mod your build deserves.

Made for More Power, Built for Street Legends

The massive 4.5-inch TIG-welded stainless steel body lets your turbo breathe free. That means spool-up happens quicker, throttle response jumps, and power increases instantly, even more with a good tune. Ditching the stock restrictor gives you that unmistakable straight-six snarl.

Sleek Looks and Zero Hassle Fitment

Nothing ruins Saturday plans like parts that don’t fit. This downpipe pairs smoothly with your original cat-back or any aftermarket exhaust, no surprises, no hassle. The CNC-machined flange transitions cleanly from turbo to mid pipe for max flow and a stealthy underbody look.

Weekend Cruise, Track Day, or Midnight Lot, Your Call

Whether you’re lining up for a late-night highway run or parking up at your favorite burger spot, that sharper sound and snappier throttle will have everyone asking what’s under the hood. Simple install, legendary results.

Perfect for Car Meets and Late Night Cruises

No matter if you’re flexing at local meets or out chasing sunsets, this downpipe dials your BMW’s personality up to 11. Louder, quicker, and built to turn curious heads in any parking lot. It’s what you want if you love that feeling when the turbo kicks and everyone looks over.

Installation
V7 Motorsports recommends that all exterior auto body parts, including but not limited to spoilers, diffusers, and any other components made of carbon fiber or other materials, be installed by a qualified and experienced professional. Incorrect installation can lead to damage, improper fitment, or potential safety hazards. V7 Motorsports is not responsible for any damage or injury resulting from improper installation or misuse of our products. By choosing to install the product yourself, you assume all responsibility for any resulting issues or complications.

Carbon Fiber
All carbon fiber parts offered by V7 Motorsports are crafted from genuine high-quality materials for aesthetic and performance enhancements.

For the best longevity and appearance, consider professional installation and regular maintenance.
