1985 Ford Mustang - BBK Performance Exhaust System Installation
Howling Coyote Coupe Project
If you've been following us on Facebook, Twitter, and Instagram, you'll know our '85 Coyote coupe project has finally made it onto solid ground. If you haven't, well, all we can say is you're missing out.
It now has new paint, Weld RT-S wheels, massive Wilwood brakes, a new interior, and an incredible Kenny Brown suspension. Little by little, we've been installing all the necessary systems.
In this issue, we turn our attention to installing BBK Performance long-tube headers for Coyote swapped Fox-bodies and SN-95 Mustangs (PN 16340, $749). We also received an X-style mid-pipe featuring high-flow catalytic converters (PN 1786, $479). But the highlight of this exhaust system is BBK's all-new Varitune mufflers.
"For years, Mustang enthusiasts have made trade-offs when it comes to picking a performance muffler or axle-back exhaust," explained Brian Murphy, owner of BBK Performance. "Utilizing our 25 years of experience as one of the best known and largest performance brands for aftermarket Mustang exhaust and induction upgrades, our research and design team set out to build a performance muffler that would give enthusiasts the best of both worlds.
"With the Varitune muffler, a 3-inch internal power valve allows enthusiasts to adjust the sound and performance levels with the simple twist of a wrench. This new technology allows you to literally go from a mellow-but-throaty, three-chamber design, to a more radical and even higher-flowing, straight-through design in just minutes."
BBK Varitune mufflers are available in either aluminized or stainless steel, and sell for $109 to $129 each depending on size. A full line of after-cat Varitune systems will hit the market shelves in late 2013.
We haven't fired the ol' coupe up yet, but there's no doubt it's going to sound wicked. We'll be sure to update you with how well these new mufflers adjust, and how quiet and loud they can get.
