Wow, what an amazing product .. Put these on my 2010 R/T 6-speed and the sound is "purrfect". A very deep "bark" at start up had people peeking out to see what was going on .. And the "growl" leaving a light is just right. Best of all, the car retains much of the same cabin noise as stock when cruising on the highway .. I am extremely happy with this purchase.

Just bought a brand new Challenger RT 6 Spd with the Trak Pak. Put the glasspacks on the next day and what a difference it made! Sounds better than other pipes that cost hundreds more! Glasspacks are the perfect middle ground for the exhaust loudness. Not obnoxious and not quiet either. A great product for the money!!!! Oh, and you can put them on yourself. Its so easy even I could do it!!!

It was an easy install to put the GP250CE glasspacks on my 2012 R/T with track pack, and I love the sound! It harkens back to the '70s muscle car sound. I have to say it is louder than I thought it'd be, but that suits me fine. Under steady throttle, it probably is 6 db louder inside the car. But get on it at all, and it really growls. My wife and I will be taking a couple cross-country trips in the Challenger and I'm interested to see how she does after 8-12 hrs/day in the car.

2010 challenger 6db glasspack

Just installed a set of your pipes on my Challenger RT and couldn't be happier. The 6db resonator kit makes the car sound better than I expected with just enough growl not to wake the neighbors. My Challenger now sounds like it should, and reminds of the day when cars where cars and a rice burner was just a bad cook. Thanks, Gary NY
Just installed last night ..
