Emissions test coming

[2006PSDSD]

I need to make my delete pipe so that I can put my cat back in for the test. I can't find anything reliable to attach them. I want flanges like these

But if there is another way, I'm all ears. I realize that my cat piping is smaller, I have a welder

Nick, I have the same problem. I've looked and looked for a reducer of some sort that will bolt in/out to no avail.

I think I'm going to weld some reducers on mine and those type of flanges as well...good idea.

The flanges are the only way to do it unless you cut them out and weld them back in every time...I had to do this on my chevy gasser every two years...I had the muffler shop just weld some flanges on and was done with it...worked out well..no exhaust leaks...

Damn Mike, I didn't think you guys had to worry about emissions down there

I don't want mine permanent, I want to remove it when done with the test. Sort of defeats the purpose of having a TB 4" exhaust leaving the stock cat in, plus the added EGT's. Exhaust will only flow as well as its smallest component. I'll let you know what I find

We don't yet...I'm all about being prepared...it's coming, I'm sure.

I don't want to have to scramble looking for crap at the last moment.

You fellas should check a couple of your local Big Trucks shops...repairs and parts for the big guys...I'm sure you'll find something there or they will know where to go.

I here that. But, if you have the money, I'm sure you can get a exhaust shop to do it, don't know what it would cost though

Never thought about that, I'll check it out, thanks

I dont think it was more than 100 bucks here when I did mine....depends on the shop...on shop said they wouldnt even tough it unless I had a brand new cat to go in...so I went to the next one and no problems there..

Good luck

My 4" TB came with adapters to put in my cat, and a delete pipe. Is this not common?

That is what I pretty much made for my old truck...even this new truck has a straight pipe so ill have to do it again to this one when the time comes...the guy at the shop made me a pice of straight pipe with flanges that matched up with the other flqnges...only took about 10 mins to swap out or less when needed...
