2007 Dodge Charger SRT8: Highs and Lows of the JBA Exhaust
June 24, 2015
I was talking about the aftermarket exhaust system on our 2007 Dodge Charger SRT8 with new-guy Jonathan Elfalan, when E-I-C Oldham did a "drive-by" and stopped at my desk to critique the crappy photo I had taken.
Trying to move things away from my untrained photo eye, I dug myself a deeper hole when I said I had never heard of JBA before.
"What's the matter with you?" he asked. "They've been doing exhaust systems for years. And they're local too, based here in Southern California."
Then he docked me a day's wages for my aftermarket ineptitude.
I may not have heard of JBA Performance Exhaust before, but I do know the system on our Charger sounds great. Most of the time.
It gives a manly bark on startup, then adds the kind of low-rpm V8 rumble that the stock system doesn't deliver. It sounds burly even when driving slowly in the Edmunds parking garage, but it especially comes into its own at full throttle. Then you're getting not just the rumbly exhaust, but a thrilling concoction with the 6.1-liter, 425-horsepower V8.
But after driving the Charger for awhile, I started to notice a strange tone or reverberation filling the cabin at certain revs. Most specifically when dipping slightly into the throttle from 2,000-2,500 rpm. Do it enough and it can tire the ears. Steady-throttle highway running is fine, but ask for just a bit more power in that rev range and the exhaust gets boomy. Two different passengers over the weekend noticed.
Want to know how to make it worse? Lower the rear seats, say for hauling a bicycle, something I've been known to do.
No. I'm just saying this exhaust produces an occasionally annoying tone at certain rpm that just happens to unfortunately correspond with often-typical highway speed. The rest of the time it sounds terrific. And because of that, I don't mind putting up with it.
