Upgrade from the standard B58 downpipe to the catless Norcal Dynamics B58 downpipe for maximum airflow, performance and sound.
The Norcal Dynamics Catless B58 Downpipe is a must-have upgrade for any BMW enthusiast looking to maximize the performance of their B58 engine. Constructed from premium materials, this downpipe is designed to provide maximum exhaust flow and improve turbo spool time, resulting in increased power and torque.
Our B58 downpipes are constructed from high quality 304 stainless steel that provides excellent durability and corrosion resistance. Catless design eliminates restrictive catalytic converters, allows for maximum exhaust flow and reduces back pressure. This results in a significant increase in power and throttle response and a more aggressive exhaust note, and is designed to be a direct bolt-on replacement for your factory downpipe, making installation quick and easy. And the downpipe is designed to work seamlessly with the factory exhaust system, so you never have to worry about compatibility issues.
Overall, the Norcal Dynamics Catless B58 Downpipe is a must-have upgrade for any BMW B58 engine owner looking to improve performance and maximize their vehicle's potential.

Very good quality
Absolutely love this spoiler on my F80. Fitment is perfect. Quality is noticeably great, and the high kick design really makes effort put into installing this mod, worth it. 10/10 recommend.

Was a little painful install but the outcome is speechless. Look amazing and sounds even better.
S55 M3/M4/M2C Norcal Dynamics Silicone Front Mount Intakes - F80/F82/F83/F87
A stronger metal if possible because I did not expect a crack to form after the valve cover was just put on thirty minutes prior.
this looks super good and feels great
Have not installed yet, but 3m adhesive completely rings the contact surface, and the reflectors looks great!
Looks great. Fitment is spot on! Super flush. Material is really good. Strong but light.
Fit well and it was easy to install so it’s a great product!
Downpipe is light, looks really great in person, and fits very well. Install is very simple and it sounds great.
Great product, very well made!

Carbon fiber looks amazing, really makes the rear look so much better. Although I recommend getting a better adhesive tape for installation.

Had a smooth and easy time shopping online. The website was user-friendly, the product matched the description, well packaged and delivery was fast. I’m happy with my purchase and will definitely shop here again. S/o for the snack.
Super easy to install and really gives my M3 some attitude. Highly recommended
Love it
PSM Style High Kick Carbon Fiber Trunk Spoiler - BMW G80 M3 & G20 3 Series
I love it. Big upgrade over the stock piece of junk for your M car that slides forward and aft when it easily breaks. Looks so much better than that cheap plastic and is built a lot more solid with its partial carbon fiber (CF) construction. The Alcantara is an upgraded look for an already sport/luxury interior. I am so thrilled I am doing the handbrake in CF / Alcantara, the shift knob & boot - CF / Alcantara, and lastly the steering wheel also in both.
Fit was perfect, goes great with my new diamond black tips and M Sport kit from Norcal. Easy to install and looks awesome.
Fits very good
Fitment was absolutely perfect and looked amazing on my car. However, the parking sensor bracket mounting tape came melted and completely unusable, I don’t believe this was a result of shipping as the provided tape for the rear bumper was fine only the front was problematic. In the end though however compared to other kits I’ve seen on other F30s this one is way above the rest in terms of fitment and quality especially for the price.
The shroud was as described, excellent weight reduction and looks good under the hood. Check the video out on instagram @g80_gtr
CARBON FIBER FRONT ENGINE BAY SHROUD FOR G80 / G82 / G87 BMW M3 M4 M2
They don’t come out as far as originals, but it’s not really noticeable. So much better looking than factory!
Love them! Been on for about a month. On a F32 with Adaptive LED (M4 headlights). In and out within 5 minutes. AND comes with the whole module. Best price and QUICK shipping
Loving the Amber DRL lights. It’s giving my F80 a way meaner and cleaner look than the CS yellow DRL
Look nice...
Quick shipping, showed up in really good condition. Looks very good, just as specified on the website. Really good fitment and easy to install. Will definitely be shopping here again!

Pleased!
I have a 2013 E92 335i LCI, They look great, fit very well and are easy to install. Packaged very nicely! Nice deep black color!
I got this not sure how it would fit but it’s as close as you can get without getting a spoiler custom fitted to your car. And with simple adhesive strips this spoiler has your BMW looking soooo much better with a simple touch. I love it!
I had the spoiler purchased as a gift a week ago fitment and the looks are on point with this thing. Super aggressive look from the back makes the whole car stand out. I highly recommend this if you wanna stand out with a aggressive style!
PSM High Kick Carbon Fiber Trunk Spoiler - BMW F30 / F80 / F82
I got the smoked version so when they are off they are completely black and accent the black/carbon fiber aspects of the rear nicely. When they are on they are TRULY UNIQUE looking. 100% happy with them! Jack went out of his way to deliver them to the shop for me as well so great customer service.
Flawless fitment
