I have ample access to 4 and 5 inch exhaust where I work and was wondering if anyone has used it on their cummins? I know on semi trucks I use it lots but theres big brackets and stuff that support entire system to frame and under our trucks there isnt many brackets. im just wondering if the flexpipe will rattle to **** or not? I was wanting to use it in place of the Catylic Converter? Has anyone used it in place of the muffler?

 

maybe ill be the first to do it. Ill be in guiness books

 

I said in your other post that I did and have no problems

 

oh sorry. did u use 2 4 inch stepclamps with it or how did you seal it?

 

I used 2 4" clamps and on the rear I used a hanger/bracket bolted to the frame for support, I got that at NAPA

 

That reminds me I need to cut out a section of pipe and put a piece of flex pipe in there. Having solid pipe all the way up to the turbo is bad when you drive up and down logging roads. I've had to retighten the clamp at the turbo several times cause it comes loose.

 

yeah that could happen
