It comes standard with factory size connection to be compatible with factory midsection which is 2.75 in diameter. I actually contacted the seller on ebay his name is Tom and requested to do oversized 3 inch connection since I was going with to make 3 inch midsection as well, he did no problem at no additional cost. Now I have full 3 inch downpipe alone with 3 inch midsection all the way to back of the car, for the midsection I went to my local muffler shop 3 inch bent pipe cost me $90, so total cost for the hardware part of this mod was $450. I see he does not have them in stock anymore I would send him a message to see if he can make you one, you can't beat his price and its a quality downpipe full ss welds are beautiful. As for the DOC Cat for now I'm running without it straight pipe style, diesel smell does not bother me at all for now, I can always add a cat down the road, I know Rawtecinc uses GESi cats on their midsections I'm not sure what everybody else is using. Personally I did not delete egr its not mandatory, since you can have it coded out and unplug the connectors that way it will not open and will work the same way as if you put a block off plate there, not worth the hassle imo removing it. Hope this helps. |
Thanks for the informative post! I did contact Tom before you made this post because I saw you had used this pipe, he said he will have more in stock this week, but he doesn't make a midpipe.
I definitely want to get a DOC so this complicates things a bit vs. getting a simple straight pipe. I looked up GESi on ebay and they seem to make high performance straight-through cats but I don't see any DOC's, only gasoline engine ones.
Would anyone have concrete links to any Diesel Oxidation Catalysts that would be ideal for what we're doing here?
Also, I have been pondering on whether or not to completely remove the EGR hardware as well as the SCR tanks, and what to do with the DPF. If I sell all of these components, I think it will pay back for the parts for the delete. However, should I ever need to convert it back to stock, I would have to source everything anew, and it would complicate matters greatly. So far, I am leaning towards keeping everything in the car, and putting the DPF & SCR cats away in storage for now. What did you guys do with your hardware?
And what did you guys do with the coolant lines for the DEF injector?
