Hmm this is one of the things I have been looking for. I run a SuperTrapp on my race cars. It allows me to adjust the backpressure of the exaust as well as adjust the loudness. This is very interesting. Does anyone havs a Particle Filter on their CRD or is that a europe only option? How many mufflers/resonators are there on the CRD? Ihave not gotten mine yet but I hope to have it in a few weeks. Does opening ut the exaust help any like maybe to 3"?
Not on US model till 2009 if I remember right, but could be on 20007 model. I just don't remember when it was said they would be on US diesels. One muffler is all it has, no resonator. Yes a 4 inch exhuast is about the bang for your buck mod you could do for the CRD, I believe it has a 2.5" exhuast. It may have been that it was just necked down to 2.5" at the muffler to be able to use same muffler & tail pipe for all three engines.
