so my buddy the welder said that he could build me a custom 3"dp. He says that the only thing he needs is a good flange. My question is, would it be possible to use the existing flange to build off of? I have my doubts as to If this will work or not, but this dude is the only one I would trust with such an enormous task.

 

you can cut off and use tthe existing flange.

 

if he does a good job he may be able to sell em to the rest of us

 

I will talk to him about it tomorrow.

 

i know this is a bit late however i noticed this thread today i did the same way to my dp i cutout the existing flange and used it on 3"dp. however make sure it is sealed right or you'll have a leak. goodluck

 

Mine is a 225, so I think it will be a little different. But yes, I'm planning on using my existing flange.

 

you know, my first shot would be just to use the exsisting flange like your doing, or i saw on 42dd website that they will sell you flanges. But hey..since you already have the flange on your factory dp right now, why not just use it, save some money from not buying one, and by your women something shinny lol

 

Your response was making a lot of sense until you said: "and buy your women something shinny"

 

hahah now i dont know if that was a sarcastic comment lol, but if it wasnt, wat i meant was.....with the money he'd be saving from not buyin a flange from 42dd, he would have some extra MONEY to buy is women something shinny(figure of speech, like a ring, or necklace) ahhha. If that was sarcastic, sorry about my rebudel, i love you, and we can still be friends on the forum lol.

 

^ all buying women crap aside!! What about the O2 sensor??! I was going to go to a exhaust shop and have em do the same thing. But I was just wondering about the O2 thing?

And has anyone gone to a exhaust shop and have them do this and how $$$ do u think it will cast
