fLOWMASTER MUFFLERS
 

I am looking to add some deep rumble to my 2014 SS, I have the dual outlet per side (NPP) right now and I like the look just wanted to add some Flowmaster mufflers to them. However, I cannot find that option anywhere, Summit told me I had to get an axle back or Cat-back system, most will not sell/ship to CA. Does anyone have real experience with this? Thoughts?
