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.
Turner set out to amplify the G80/G82 with a proper catback exhaust system. To accomplish this goal, the engineers at Turner 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. Turner 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 Turner Race Inspired Catback exhaust being the clear answer in your mission to find the best exhaust for your S58 powered G80 or G82.
