I bought a 5 inch exhaust that came with this four inch down pipe. It has never been installed on the truck. It was bought for a 2003 Dodge Ram Cummins but should work on other trucks.

$75 for the down pipe. I will ship if needed. I accept paypal or cash.

would it work a 99 with a hx super 40?

 

I'm not sure. That is something you would have to find out. I think it should, just not 100% sure.

 

Is this a true 4" or is it 3.5" to 4" to fit on the stock elbow for the 03/04? How much to ship it and the 4" exhaust you have up to 40176?

 

It's a true four inch being the reason I couldn't use it. I have the 3.5 to a 4 inch downpipe now because of the fact I have a pac brake and a htt turbo made for the 03-04 trucks with the 3.5 downpipe. Shipping would be about $45 and it says it would take two days to get to that zip.
