The Nissan GT-R is a modern masterpiece but were it not for the brilliance of the Skyline GT-Rs that came before it, Nissan may have peaked with its Z cars. That's not necessarily a bad thing, but hordes of enthusiasts have been attracted to the brand because of the turbocharged icon that came to be known as Godzilla. Skyline GT-Rs are now among the most expensive import tuner cars you can get, yet the people who buy them are not typically collectors who store these beauties in garages for years on end; they drive their cars. Nissan recognizes the adoration it has garnered and is always looking to cater to fans of the AWD beast with its Nismo Heritage Parts program, and now that program has been expanded to include titanium exhausts. Epic.

As anyone who has heard such a system on a car can attest, titanium makes a car sound spectacular. Four years after the introduction of the Heritage program, which started with a little more than 80 parts and now includes more than 300, three made-to-order systems are now on offer with a diamond-like coating on Nismo-branded exhaust finishers.

Nissan says that this new black-colored coating will suppress color changes due to exhaust heat, although we're not sure why you'd want to rob yourself of the gorgeous gold, purple, and blue hues that burnt titanium takes on. But beyond aural pleasure and an aesthetic enhancement, these systems have a real performance benefit too.

Nissan promises reduced exhaust pressure, resulting in 7% better output and less weight - these finishers are around 5.6 pounds lighter than original components. It's unclear why (Nissan hasn't given a reason) but the exhaust upgrades are only recommended on cars with R3 or R4 engine codes, not S1 or S2 motors. All we know is that it's related to the different turbochargers of the latter motors. R32 and R34 models can all benefit from the upgrade, but the R33 will only work if it's a coupe. As for pricing, the R32 and R33 systems cost the equivalent of approximately $6,360 while the R34 setup is a little dearer at the equivalent of around $6,460.
