We want to speak to all the readers who are over 25 years old for a minute. After all, this new muffler is specifically going to appeal to you-still liking the loud rumble of a throaty V-8 when on the throttle, but tired of waking up your neighbors when you drive home at midnight. Open pipes, gutted mufflers, bored-out cats-those are cool when you're young and driving just few miles a day. But when you start getting a little older, you start to hear a ringing in your ears, and you start noticing people looking at you like you're an A-hole, many of us will give up the thunderous pipes on our trucks for something a bit more tame around town.
And this is why Dynomax released their new VT muffler. The VT stands for Valve Technology, and the butterfly valve built into the muffler is what makes it so trick. The muffler stays quiet when driving normally around town or on the highway, but when you hit the throttle and push more exhaust down the pipes, the valve opens up, allows the increased airflow to exit smoothly, and make a throaty rumble that reminds you it's a Dynomax performance muffler.
We drove down to Mesa Muffler in Costa Mesa, California, to put one on a friend's '07 Chevy 1500 to try out in place of his stock muffler. Our friend was really concerned about being too loud around town, but liked the idea of his truck getting loud when he gassed it. We knew he was the perfect candidate.
A half-hour later, Mesa Muffler had welded the new VT muffler in place of our stock one, and we were on the roads trying it out. Was our friend happy? Oh yes. The exhaust is almost silent when he's cruising, but it gets loud when he stomps the gas pedal. Interested in what it sounds like? Check out www.off-roadweb.com/videos/index.html.
