On a cost effective and availability level, crush bend will do the job. Mandrel bends will be ideal, but I wasn't looking for efficient flow, hoping to gain extra power. Crush bend will cause a bit of restriction to mimic some of the stock levels.
Not sure if my phone camera can record the sound clip properly, but I'll give it a try.

I finally got my quad tips. Replaced center muffler with magnaflow x pipe 11385, ultra vibrant ultra quiet resonators 1140 x2, and 3.5 tips. It is kind of loud between 1800 to 2300 rpm. Im thinking of adding 2 more magnaflow resonators 14415 next to the xpipe to quiet it down. Do you guys have any suggestions? Thanks

Did you keep the stock resonators? I can't tell by your pictures. But Yea, I've been thinking about adding another 18" resonator on both sides to bring down the noise at lower rpm. I know it's defeating a purpose of having an exhaust that doesn't purr.
