Unlock unparalleled performance with Palenon Performance’s 5-Inch bmw B58 Downpipe, the largest on the market For Gen1 & Gen2 BMW. Engineered for 2020+ Supra 3.0T & 2016-present BMW models including M340i, M440i, M240i, X5 40i, Z4, 440i, 540i, 640i, and 740i, this b58 downpipe features a smooth transition from 4.5” to 5” to 4” and ultimately to the OEM connection of 3.15”. Unlike other downpipes that quickly neck down to 3” at the flex joint, our design maintains larger diameters throughout, ensuring optimal flow right after the turbo.

Crafted from full stainless steel with a stainless steel flex joint and an inner stainless liner, this downpipe is TIG welded and back-purged for exceptional strength and longevity. Experience a deeper exhaust note, improved spool response, and increased power with easy installation compatibility for both factory and aftermarket exhaust systems.

  • Faster Spool: Improved turbo response and quicker spool times.
  • Increased Power: 30HP+ Noticeable horsepower and torque gains with proper tune.
  • Warm and Deep Exhaust Note: Enjoy a richer, more warm sound.
  • Easy Installation: Fits both right and left-hand drive vehicles without modifications.

Our racing-grade downpipes are expertly crafted from premium stainless steel, using precise and standardized bending techniques to ensure optimal performance and thrilling exhaust note. Our downpipe pricing is U.S. market guaranteed. With an unwavering commitment to both price and quality, we adhere to a "customer-first" standard, ensuring that our products exceed expectations without compromise.

Cel Delete Kit

Installing b58 catless downpipes will trigger a check engine light (CEL) due to the absence of OEM catalysts. To eliminate the CEL without a tune, we offer a CEL Delete Kit featuring O2 sensor spacers that comply with BMW’s emissions parameters, effectively removing the CEL.

Vehicles manufactured from 2019 onward are highly sensitive, and the Check Engine Light (CEL) may not always be eliminated. However, the modification may help delay its activation.

Excellent Air filter - Easy installation.
Style: BE-743 1-Pack
Excellent AC and Heater Cabinet odor defense air filter. I noticed immediately the smell coming out of the vents was fresher and the musty smell that was coming from the vents was crisper and cleaner. Very easy installation that you can do yourself and don’t need to pay a shop to do. The price is one of the best online and coms in quickly. It’s very sturdy, filter quality is excellent and it definitely improves the air quality and flow in your car. Fits perfectly like any OEM filter, this is a great buy for the price of an installation that will take you Les then 10 minutes to do yourself.

Great filter and easy installation
Style: BE-159 1-Pack, Style: BE-159 1-Pack
For my 2016 Hyundai Sonata Hybrid Limited. I cannot believe I paid so much more for a brand-name filter that does the same thing as this one. It is made of the same material as the dealer one I took out. Very easy to install, cant believe I paid for this to be done in the past with oil changes. Requires no tools and did not get dirty at all. No mechanical skills needed, especially if you run into trouble and can use YouTube. PROS - great quality, cannot tell that it is after-market - very professionally made, not irregularities seen - excellent fit in position, no adjustment needed - very easy to install, cannot believe I paid to have this done in the past - no mechanical skills needed to install - great price compared to what big name productions want for the same thing - cannot tell the difference in air quality between this and the dealer filter I took out - removes outside odor completely - did not require tools are getting dirty CONS - None
