Inexpensive Exhaust Modification
My 300C looks mean and tough. On a race track, it tears up the competition.
The Volant CAI has a sweet 'big V8' induction sound.
There's just one problem. My exhaust sounds like a DeVille in a funeral procession.
Quiet. Stone cold silent. I can't stand it any more!
Following the lead of a few other members, I took the plunge last week. My Black Beauty went up on the hoist. The 2 big rear resonators were surgically extracted. Two straight pipes were pressure bent to shape. Then 2 Reactive 4" tips were welded in place.
Lowered the hoist. Everyone from the muffer shop standing, waiting, listening. Fired her up. A sweet, deep, bump bu de bump bu de bump bu de burble issued out the back pipes. A big V8 awakening from a sleep. Gotta love that sound!
Blip the throttle - stand back - a menacing growl spits out - echoing through the work bays.
They all want to hear it on the road under full power. I circle the back streets and pass by the shop along the main road. WOT -serious power; kick-butt acceleration - and a sound that has jumped from the flames of Hell.
I circle back to see a bunch of Midas monkeys with silly grins on their greasy faces.
Yeah, they're happy, but will it pass the wifey test? Friday, we head out on a 1000 mile round trip to a family gathering. I start up inside my garage. No comment. Roll out with mild acceleration - some exhaust note - again no comment. 20 minutes later, I pull out to pass an 18 wheeler - 3/4 throttle. the beast jumps forward with a roar. After the pass, my wife says, "Boy, does this car ever move!"
The car is still quiet at cruising - a distant exhaust note but no drone or resonance. No difference when going into 4 cylinder mode. No more comments about the sound - but she is used to me having noisy cars in the past.
Lots of positive comments from my relatives - especially the burble on idle.
I am happy with this inexpensive mod. Even if I go to a "tuned" system such as Borla or Zoomers, the resonators would have to come off.
Will I go to a fully tuned system? I'm not sure. Once a good chip programmer is out there and we can see some dyno numbers - I would go to a full system and headers - if a significant power boost is to be found.
2015 Charger Hellcat is in the stable!
