Re: WK CRD muffler chop
I removed the resonator on my Jeep and I didn't really notice any difference, expect maybe just a bit more exhaust note. There is no efficiency gain from what I noticed. I removed it because I had the tube around and want to install a rear skid plate that might interfere. The resonator is pass through and weights around 15 lbs. It won't set off any codes. The 2.75" exhaust tubing after the dpf is more than enough for stock to modified power levels. The dpf pipe is 2.5" so you would need to get rid of that to see any flow improvements. I wouldn't buy the mbrp system.
