Used these to replace the resonators on a 2023 challenger gt v6 and pulled the the mufflers. Much louder and throaty ar 40Mph and below on surface streets and if you want them to roar put the pedal where it belongs....to the floor!!! yet atb75 mph on the freeway they are nice and mellow. VERY HAPPY WITH THESE!! Also have a single one on a 2018 wrangler jlu with just 16 inches of pipe coming off it under the seats. Also sounds great!!!

Had to put new exhaust on my old small block chevy pickup. Dual straight pipes with stacks at first, figure out mufflers later. Badass, but really loud in that metal cab. Watched some vidieos, finally went with the 10416 Magnaflows. About half as loud as straight pipes I think. Way better, still loud when when I get on it, nicer sound. Some drone in low rpm but overall, like them a lot.
