Holley Announces Hooker BlackHeart Exhausts for ‘99-‘15 Mazda Miata

Because power is never something people think of when they picture a Mazda Miata, the model makes up for its lackluster acceleration with agility, braking performance, and sense of occasion. It’s the original 1.6-liter engines that are most often criticized for being anemic. The successive engines are much torquier — first displacing 1.8 and then a full 2-liters. Now, Hooker Headers has just released a new set of exhaust systems for those larger motors to make those generations extra lively.

To drag a little more punch out of the engines in the second- and third-generation Miatas, parent-company Holley introduced its new line of Hooker BlackHeart exhaust systems — both in axle-back and cat-back configurations. Utilizing the factory mounting locations, these exhaust systems are easy to install and offer maximum clearance. They’re also lightweight, robust, and covered by a limited lifetime warranty.

NB Miata (1999-2005)

The BlackHeart’s straight-through muffler design produces a deep, aggressive tone without the drone. Constructed from 2.25-inch, 18-gauge, mandrel-bent, 304 stainless-steel construction, the exhaust can take a beating — from curbs, debris, and the elements. The exhaust also reduces weight — up to 33-percent over the factory exhaust system (with a muffler). The axle-back saves seven pounds, and the cat-back saves a full ten.

The axle-back produces an extra 2.84 horsepower and 2.38 lb-ft of torque over the factory exhaust.

In a featherweight like the ~2,200-pound NB Miata, now lightened with the cat-back exhaust system, the gained 4.15 horsepower and 3.8 lb-ft of torque is easily felt. Best of all, the bump in power is accompanied by a growl which is sonorous and smooth, and in no way droning or raspy, as you can hear below:

For a more subdued exhaust note, the axle-back exhaust might be the ticket.

The NC (2006-2015)

Some prefer the newer NC Miata and its larger 2.0-liter engine. As you might imagine, these exhausts have a slightly greater payoff with added displacement. They also give the NC Miata a more distinguished appearance thanks to prominent stainless-steel exhaust tips adorned with laser-etched BlackHeart logos.

Strong low-end gains help the Miata feel even lighter and more agile than it is already.

Both use an x-merged muffler for a deep, sporty tone, and 304 stainless-steel construction for the 2.5-inch tubing and polished 3.5-inch tips. With a larger 2.0-liter motor to build upon, the gains across the entire rev range are noticeable. An additional 8 lb-ft of torque and 6.5 horsepower can be had with the addition of the cat-back. The throaty, impressive exhaust note won’t encourage your neighbors to shoot you dirty looks.
