The Supersprint rear mufflers for the turbo Z4 is a subtle sound and performance improvement for those that think the stock muffler is too tame. This sport rear muffler is a free-flowing design with larger piping to improve flow and tune the sound. With the stock cats in place the sound is still subdued but the Supersprint muffler makes an alteration to the exhaust note to be a little more sporty and aggressive but not intrusive or obnoxious. This system includes the center X-pipe with slightly oversized piping for improved flow over the stock system. This system uses two exhaust tips per side, giving more muscle and presence like BMW uses on their "M" models.

Supersprint exhaust is widely recognized as the leader in complete exhaust system upgrades - extremely high quality, well designed for optimal flow, and amazing sound. Even at a premium price Supersprint is an unbeatable exhaust system because every aspect is done to such a high level. A Supersprint exhaust rewards you with a terrific sound, long lasting construction and excellent fitment. The Supersprint sound is very 'European' which fits the sporting sophistication of BMWs perfectly. Most systems are also modular - sections can be added or removed to custom tailor the exhaust sound to your preferance. Aside from 'Race' systems, their mufflers meet European noise laws so you get a refined and tuned sound without being excessively loud. Most Supersprint systems are built with larger diameter piping to improve exhaust flow which helps the engine do less work and make more horsepower! Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation!

section:center x-pipe + rear mufflers

connects to:factory secondary cats

tip style:2 x 80mm dual round per side

material:T304 stainless steel

Fitment note: the rear bumper will have to be trimmed slightly to make room for the double tips.

BMW’s move from the S85 V10 to the S63 twin-turbo V8 brought big gains in efficiency and speed, but the factory exhaust left the soundtrack behind. The Valvetronic Designs Valved Exhaust System restores the drama, delivering a sharper, more engaging tone with genuine GT composure when you want it. Connecting to OEM or aftermarket downpipes, this system runs 3.0 inches from inlet to outlet and features a large X-pipe crossover for superior scavenging and response. Exhaust flow then passes through our valved mufflers, exiting via your choice of premium tips. A vacuum-actuated valve system with an included controller ties into the factory harness for full, on-demand sound control.

The F90 M5 continues the powerful legacy of the S63 4.4L twin-turbo engine, yet the factory exhaust system often keeps its true acoustic potential far too quiet. The Valvetronic Designs Valved Titanium Cat-Back system finally unlocks the aggressive soundtrack this car deserves, providing a refined tone for daily driving and a ferocious roar when you decide to push the limits. Crafted entirely from premium Grade 5 titanium with 3.0" tubing from the inlet to the outlet, this lightweight masterpiece integrates seamlessly with your factory controls or operates via a standalone remote for absolute command over your driving experience. Engineered for maximum performance, the forward-mounted, large cross-section X-Pipe significantly improves exhaust scavenging and smooths the overall tone, virtually eliminating unwanted rasp, which is particularly beneficial for vehicles equipped with aftermarket downpipes. This free-flow architecture reduces back pressure to deliver sharper throttle response and a much cleaner note at the top of the rev range. For effortless versatility, the integrated valve control ties directly into the car’s ECU through the Sport and Sport+ settings, while the included standalone remote ensures you can instantly toggle between a stealthy profile and an unrestricted scream in any drive mode.

The Track Edition comes equipped with bullet resonators in the mid-pipes, and shares the same bespoke stainless steel stamped merge and precision engineering as its Touring Edition counterpart, minus AWE’s patented drone-canceling solution. Drivers can expect an 11 lb weight savings compared to stock. In place of the resonators in the rear are dual Track Edition straight sections. As a result, this version is known to get (really) rowdy in mid-range acceleration and deceleration and may be too much for many. Due to this reason, AWE Track Edition Exhausts cannot be returned based on sound preference. You’ve been warned.

The BMW X7 M60i and Alpina XB7 deliver immense performance and luxury—but their factory exhaust holds back the soundtrack these SUVs deserve. The Valvetronic Designs Valved Cat-Back transforms the experience with a more raw, motorsport-inspired tone, sharper gearshift snaps, and an enhanced character throughout the rev range. Connecting to OEM or aftermarket free-flow downpipes, this 2.75-inch system runs unrestricted from inlet to tip. In testing, we found that an unresonated design delivered the most engaging sound, producing pronounced pops and crackles when shifting, while maintaining a drone-free cabin with the valves closed. The included electronic valve controller allows you to fully control the exhaust at any RPM, unlocking maximum enjoyment whether you’re cruising in comfort or pushing the M50i powertrain to its limits.

Constructed from high-grade lightweight titanium alloys, the Evolution Line (Titanium) exhaust system has been perfectly tuned to deliver the very best aural experience in all driving modes. Through extensive testing and development, the Akrapovič sound engineers have coaxed a deep, sporty, higher-frequency V8 sound from the car’s turbo engine, more akin to that of a muscle car, while keeping it smooth and eliminating any drone that might hamper the enjoyment. The full titanium exhaust system is finished with two sets of carbon-fibre / titanium tailpipes coming from a central muffler layout featuring two valves, one located on either side of the muffler. The housings are cast in-house in the Akrapovič foundry, and there is a cast collector on the link pipe, where gases from both sides of the engine mix, all designed to create a perfect sound. This plug-and-play exhaust system can be further regulated with the addition of the Akrapovič Sound Kit to control the valves in the exhaust and switch between the sound modes. See T#599277 for this sound kit. Fittment notice:This system does not fit on vehicles equipped with Otto particulate filter (OPF). This exhaust system is not CARB approved

At Valvetronic Designs, we’ve engineered a Titanium Valved Exhaust System to change that—delivering a sound experience worthy of the M8’s incredible capabilities. Crafted from our signature lightweight Grade 5 Titanium, this system runs a full 3-inch diameter from inlet to outlet for maximum flow. A large cross-section X-pipe is strategically placed to optimize exhaust scavenging, increasing performance while creating an aggressive yet refined tone.
