Performance Catback Exhaust for pure unrestricted power and sound. This exhaust takes out all of the stop gates and pairs with the S58 for an iconic driving experience.

If you have driven an S58 car, even in stock form it feels like the sky is the limit.(If you haven't driven one, we are not sure why you are even looking into this exhaust)

When your driving an S58 equipped car such as the G80 M3 you can put your foot to the floor and it feels like the car would keep going and going, possibly with no limit. The G80 driving experience is great but there is always room for improvement. if dropping over 40lbs from just your exhaust and the gain in flow alone aren't enough to sell you, no problem. From enhancing the exhaust with smoother flow paths and taking out the bulky and restrictive muffler we saw gains up to 10hp and 14lb of torque on the stock ecu with zero tuning. Now that there are options for plug and play tunes as well as unlocking your ECU for custom tuning there is a much larger upside for power improvements. You will have to find the other restrictions holding you back from more power because it wont be the exhausts fault, this is as free flowing as it gets.

Here at Turner our mission was to amplify the G80/G82 with a proper catback exhaust system. To accomplish this goal, our engineers increased flow, reduced weight by 26lbs, and delivered an exhaust system that captures the full unrestricted sound of the sonorous twin turbo inline-6 S58 engine. The increase in flow was gained from dual 3.0" 304 stainless steel exhaust pipes that feed into straight-through free flowing rear section. We specifically designed this catback with flow in mind to ensure the exhaust would never be a restriction. Weight reduction is achieved by replacing the factory piping with lightweight 304ss for a more-than-modest weight advantage. The best part of the Race Inspired catback is the capability to perform far beyond the point that the factory exhaust. All of this plus the direct fitment and straight forward installation leads to our Turner Race Inspired Catback exhaust being the clear answer in your mission to find the best exhaust for your S58 powered G80 or G82.

This Supersprint performance exhaust is built from the Euro exhaust layout. It features oversized dual 50mm stainless steel pipes leading from the catalytic converter. This Supersprint system has a center resonator and rear muffler with free-flow designs for a sporty sound and less restriction to free up horsepower. The sound is such a great match to the M88/S38 engine and retro cool that these cars have now. It's a classic growl and throaty sound without being overly aggressive. We've had nothing but compliments on the sound from this system. The previous mild steel versions have been discontinued - this system is now 100% T304 stainless steel!

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!

Fitment Notes: This system is not a direct fit with the US catalytic converter section. The factory system is connected with 2-bolt flanges but the Supersprint Euro system is based on the Euro 3-bolt flanges. The US cat section flanges must be removed and replaced with the triangular 3-bolt flange (BMW p/n 18111178137) and gaskets (p/n 18301723886). Or, conversely, remove the 3-bolt flanges from the Supersprint and re-weld the old 2-bolt flanges from the stock resonator section.
