Let's be honest—what's the point of owning a B58-equipped BMW if you can't hear it? The M340i and M440i both feature a bulky, suitcase-style rear muffler assembly that silences a wonderful exhaust note that the B58 was born to deliver. While full cat-back exhaust systems can be a serious investment, Turner Motorsport’s new muffler delete design offers an affordable alternative that delivers all the sound, style, and performance your B58 deserves.
This system completely transforms your BMW's character by replacing the restrictive rear muffler assembly with a high-flow, TIG-welded stainless steel setup that enhances tone, reduces weight, and maintains factory fitment and finish. The Turner Motorsport Muffler Delete features 3" primary tubing that transitions to dual 2.5" adjustable tip sections for a clean yet aggressive look. Accuseal-style slip-fit joints allow for easy adjustment and perfect tip placement inside the factory rear diffuser. Quad 2.5" tailpipes offer compatibility with your choice of Turner Motorsport exhaust tips.
The ARM Audi B9 3.0T S4 / S5 Competition FMIC is engineered to keep IAT's low during back-to-back pulls. By dramatically increasing intercooler core volume to a staggering 1,485cu/in and improving airflow efficiency with internal air channels, this system is designed to reduce heat soak, stabilize intake air temperatures, and maintain consistent performance pull after pull. Whether you have stock turbo or upgraded turbo, the ARM B9 FMIC will keep your EA839 running cool!
This direct bolt-on OEM-style intercooler features a 290% increase in airflow from the OEM intercooler, consistant performance and engineered to channel air equaly. The OEM intercooler on the Audi B9 3.0T platform is sufficient for light daily driving, but it quickly becomes a limitation under sustained boost, aggressive driving, or tuning. As intake air temperatures rise, timing is reduced and power output becomes inconsistent, making your second or third run feel like a much slower B9.
That's not it, ARM Motorsport products are covered under their lifetime warranty!
The H&R philosophy is simple and effective: To manufacture the best suspension products, using only the highest grade materials, and then back all of our products with unparalleled customer service. This philosophy has made H&R what it is today – the industry leader in high performance, quality suspension components. Be it on the street or on the track, H&R has become synonymous with consistent, proven suspension performance and quality.

Upgrading your suspension components will ensure that your vehicle has improved handling and reduced body roll. H&R springs have superb ride comfort and increased driving convenience. H&R Special Springs are high quality products—they will not set or sag, they are designed and manufactured to be strong, resilient, and more durable than other automotive coil springs. All H&R springs are crafted from a special (hf) 54SiCr6 spring steel to ensure premium quality and performance. H&R Springs are shot-peened to increase their life by more than 200%. All production is completed in-house so product quality is ensured. Each spring is 100% tested before leaving H&R’s ISO9001 certified production facility in Germany.
IE's carbon fiber intake system flows 37% more than the stock intake & inlet on the factory turbocharger and up to 61% more on hybrid turbo setups. This increase translates to a maximized flow rate that significantly improves turbo & engine efficiency resulting in power gains of up to 19HP & 21ft-lbs on tuned engines! IE's engineers took a "no expense spared" approach to design the ultimate intake system solution that delivers on looks, fit, and, most importantly - power!
Upgrade your intake with our optional cast turbo inlet for the most performance available from an intake system. This removes the significant airflow restriction from the small plastic stock inlet and maintains the largest size possible from the intake to the turbocharger. This combination increases flow from 11.52% (intake only) up to 61.49% over the stock intake and turbo inlet!
