Unlock unparalleled performance with Palenon Performance’s 5-Inch B58 Downpipe, the largest on the market. 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.

Features
- Maximum Flow: 5” diameter with smooth transitions enhances exhaust flow and reduces restriction.
- Faster Spool: Improved turbo response and quicker spool times.
- Increased Power: Noticeable horsepower and torque gains.
- Aggressive Exhaust Note: Enjoy a richer, more aggressive sound.
- Customizable Fit: The end section (3.15”) can be adjusted to fit custom exhaust setups or swapped to a 4” diameter.
- Easy Installation: Fits both right and left-hand drive vehicles without modifications.
Profile: 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.

Customer Reviews
The sound quality is awesome, and I love it!
Wow! This product is incredibly well-made and solid! Installation was a breeze, and I could feel a boost in power. Highly impressed!
The fit was perfect, and it worked exactly as intended. Gotta loves that turbo spool!
Very happy with this purchase. It arrived in less than a week, and the quality was amazing. The installation was very easy, and it sounds amazing. I highly recommend it.
I bought the 5-inch downpipe for my m340i with an O2 spacer to avoid a check engine light, but it did come on. Palenon Performance has been amazing in helping me resolve the issue. Just reach out to them on Instagram – they've been helping me fix it quickly. One of the best reasons to buy from them!
