Follow-up: Very pleased with the exhaust system. Sometimes I wish it was louder but every morning at 4:15am I'm glad it isn't. In conclusion, don't cut off your rear mufflers, get the Solo mufflers or go full cat back. These cars need the J pipe. Un-Driveable without it.

So I love the car but I do like some peace and quiet sometimes. I get a lot of road noise in the car that varies greatly on road surface. Not sure if it is the rubber floor matts, a wheel bearing going or something in the suspension telegraphing every bit of the road into the cabin. Any thoughts on ...

Never mind I found a gold mine of info!

I think I need to replace the balancer on my motor. I can see a slight wobble at idle.
Are there any tips and tricks / better pullers for the job on this car? 2013 PPV

So I took the measurements, Did the math and decided to buy the kit from SOLO

I spoke with the CEO and the sales guy and went with the MACH kit. The Mach shorty would have been better but I daily this car and I am really sick of noise in the cab.

Well here is the data:
Drone at 1800RPM in 8 cyl and 4 cyl

I have deleted my rear mufflers piped out past the bumper and hate the drone.

Has anyone ever cut open the factory mufflers, removed the factory tuned J pipe if it exists, and added it to a straight pipe?

Thoughts?

So I found this post on another forum. By Geroge C The concept behind drone is pretty simple; nearly everything has a resonant frequency...exhaust systems, electronic RLC circuits, even gravitation has resonance. At peak resonance, the amplitude of the wave at the resonant frequency shoots up to man...

So, I had the exhaust extended out the rear bumper. The motor noise is less but the Drone at 1,700 to 2,000 RPM is sitll unbearable!! I've run swamp buggies with straight open headers that were quieter than this harmonic going on in this cab! I'm ready to try custom J pipes or something, I can't sta...
