The QS Inconel ‘Titan’ system is almost a third of the weight (18 kilos ~38.7lbs) of the standard exhaust. This is a remarkable weight saving, particularly as the catalysts cores & shells (weighing 3.5 kilos) comprise such a large proportion of the total weight. Importantly this weight comes off the very rear of the car so has a profound benefit to the balance and all aspects of performance.
These systems are as close to an F1 system as exists. Utilising type 625 Inconel in .7mm and .9mm for tube, silencer casing, muffler internals and thicker Inconel for the bands and flanges. The heat-shields are fabricated from .5mm Titanium. Though Inconel does not carry any inherent weight advantage over stainless steel, the benefit is that it’s superior strength allows less (thinner) material to be used.
Plus, inconel’s far superior durability to extreme heat make it a much better material for motorsport and turbocharged applications – which is why Inconel (and not Titanium) is used for F1, IndyCars, Nascar, LeMans and just about all the top formulae.
