New Turner E46 Resonator Delete Exhaust Upgrade

Clear BMW chassis

Please ensure your correct model is selected

A new performance mid-section with an integrated X-pipe for BMW E46 323i / 328i models, designed to improve exhaust flow, sound quality, and overall driving feel. Replacing the restrictive factory midpipes, this upgrade reduces backpressure and enhances throttle response while delivering a smoother, deeper exhaust tone. The integrated X-pipe balances exhaust pulses from BMW's inline-six engine, helping to eliminate harsh rasp and create a cleaner, more refined sound under acceleration. Constructed from durable T304 stainless steel with mandrel-bent tubing, the mid-section is engineered for long-term performance and precise fitment. Designed as a direct bolt-on replacement, this lightweight mid-section pairs well with aftermarket mufflers and performance exhaust systems, making it an ideal upgrade for E46 owners looking to enhance both sound and performance.

Upgrade your BMW E46 exhaust system with the Turner Motorsport X-Pipe, ditch the bulky factory midpipes and resonator, reduce backpressure, and let your engine breathe the way it should. This free-flowing X-pipe delivers smoother exhaust tone, improved throttle response, and a noticeable performance advantage over restrictive OEM components. Factory exhaust pulses exit each cylinder separately, creating turbulence, rasp, and unwanted backpressure. A performance X-pipe merges and balances these pulses, producing a cleaner, deeper exhaust note while increasing overall exhaust efficiency. For the best sound and power gains, pair the Turner X-Pipe with a high-flow performance rear muffler. BMW’s straight-six engines, especially in the E46 323i and 328i, are known for their metallic “rasp” under load. Turner’s mid-section with an integrated X-pipe dramatically smooths the exhaust character, enhancing tone without sacrificing flow. Each system includes upgraded hardware for the downpipe connections and premium stainless steel exhaust sleeves for a perfect, leak-free fit to your factory rear section. Features and Design: Turner in-house engineered using FARO ARM laser scanning and SolidWorks 3D CAD for exact BMW E46 fitment T304 stainless steel construction with natural finish, 1.25mm wall thickness, TIG-welded and back-purged for longevity 2.0" OD stainless steel mandrel-bent tubing for maximum exhaust flow T304 stainless 12mm barbed exhaust hangers, TIG-welded in OE locations for perfect alignment Direct-fit flanges designed to bolt to factory BMW E46 downpipes Over 10 lbs of weight reduction compared to OEM midpipes Engineered for smoother flow, lower backpressure, and enhanced performance on E46 323/328 models Kit Contents: E46 323i / 328i Mid-Section with Integrated Turner X-Pipe New rear exhaust brace New downpipe hardware (replaces seized factory studs) Dual stainless exhaust sleeve clamps for easy installation to the factory rear section

Maxiumum Flow Pro5R Filter

This intake kit replaces your restrictive factory air box. It features a 3-angle aluminum velocity stack adapter, 1.6mm powder-coated steel heat shield, trim sealed to seal out hot engine air, and a custom aFe brand cotton filter.

This version uses aFe's highest flowing filter media, which uses a lightly oil gauze to filter out dirt and particulates, while allowing more air to flow to the intake. For the best flowing filter, with the best performance gain, we always recommend this standard aFe filter media (often called "Pro5R ", which has a blue pre-oiled filter media). We also carry this filter in the "ProDry" grey filter media, which is oil-free for only slightly less performance and no maintenance.

By removing your stock intake air box, you are removing the most restrictive portion of your intake system, increasing both horse power and torque, improving acceleration as well as throttle response.

aFe has reported gains as high as 6 hp and 12 lb/ft torque

For the maximum benefit in performance, we recommend upgrading your engine software with the Shark Injector (Click here for more info on the Shark Injector performance software.)

This aFe intake fits the following BMWs:
1999-2006 E46 BMW 323i 323ci 328i 328ci 330i 330ci 330xi
2001-2006 E46 BMW 325i 325ci 325xi - Only with M54 Engine - Not for SULEV M56 engine

Updated in 2020 to provide additional reinforcement! The E46 rear driveline and suspension are very similar to that of the E36. An unfortunate side effect of this is that the E46 also shares some of the same problems as the E36. One of these problems is the rear mounting points for the subframe, which can rip out from their spots in the sheet metal. This happens because the rear differential transmits the torsional load from the engine through the subframe, then into the chassis. This constant loading and unloading weakens the sheet metal and causes it to fatigue and separate from the chassis. BMW tried to fix this problem in the E46 by placing a cross member on the front two mounting points of the subframe. This cross member keeps the front mounting points from having problems by placing the bushing and the stud in double-sheer, thus reducing the twisting action on the sheet metal. The unfortunate side effect of this is that the load from the front of the subframe now gets transmitted to the left rear of the subframe. This is where we have seen many failures of the chassis on low mileage street cars and race cars. BMW has also tried to prevent the issue by injecting foam into the open space between the underside of the chassis and the top of the trunk. This seems to work but that does not address the issues of the spot welds failing on the sheetmetal. It can also make any additional work there harder and almost impossible to weld against. Our reinforcement kit has proven over and over again to be effective and the easiest to work with in the long run.

This product reinforces the chassis sheet metal at the subframe mounting points. We do this by thickening the metal and distributing the load over a larger area. This kit will save time when repairing the chassis, and is also strongly recommended as a preventative maintenance item.
