Just installed a Corsa Extreme Cat Back on my 2019 Challenger Hellcat. Overall I am very pleased with it. It makes cold start very nice and loud. Sounds considerably more aggressive at cold idle. Not insanely loud but much louder than stock. As advertised, when you get on it, it is most definitely louder and more aggressive sounding. It is not insanely loud. If you drive gently it’s probably not any louder than stock - which is perfect for those times you really don’t the want any additional attention.
I also was trying to eliminate the 80mph drone I had with the stock exhaust. I have rear seat delete which probably makes it worse. I would say the Corsa cuts the 80mph drone by 60-70%.
So for me it accomplishes my goals. Much louder at cold start up and when driven aggressively but not insanely loud. Quiet when driven tamely. And much less highway drone. A win.
I’m not sure if it’s just a 2019 issue, but the directions are absolutely wrong for measuring the cuts forward of the active exhaust valves. I think the mid muffler has changed a lot. The only way to get the cut right is to overlay the new exhaust on the old exhaust and do some measuring. The directions most definitely need to be updated for 2019.
I got the twin round tips in black. The finish is fantastic. The twin round tips are a bit narrower than the bumper cut out. Not perfect, but I like it better than the square tips. The black finish is absolutely the way to go - looks amazing.
Worth it? I don’t know. I paid about $1650. I guess I am very glad to cut down the 80mph drone. That probably makes it worth it for me. The sound is great, but is it really worth $1650 to change the sound....maybe. I’ll see what I think after having it for a while.
I think the Extreme is the only sound level to go with. It’s louder, but not insane. I think I would have been very disappointed with the Sport sound level.
No other mods - so far.
