I put a 5'' magnaflow on my 05 ctd. My truck ran like CRAP!!!!! I did not research exhaust systems. My 600$ mistake!!I think a 5'' exhaust and a stock engine is a bad combo. I had a choice of buying a new 4'' exhaust or a power mod. I bought a edge/juice/att. I was not ready to jump into the bomb pool just yet,but did not have a choice!!My truck runs GREAT now. Back to the magnaflow,the craftmenship was very POOR!! I think the person who welded the hangers must have smoked there wheaties for breakfast. Only one hanger was in the right spot. When i called customer service about my complaints they told me i should remove it and sell it on e-bay!!The sound is obnoxius,my cummins sounds like 2 HONDA'S. Thats not what i was looking for. I will be replacing it this spring. GOOD LUCK!!
