It did NOT fit....
Ordered this guy for a new setup with a borg s300sxe on a stock manifold. Needless to say, it did not fit. Nore was it ever gonna fit. I'm not sure if they sent me the wrong dp or the one they sent was a defect. I lined this piece up on a bench with another dp and it seems that the bend away from the engine and the *90 at the bottom were not bent enough. I ended up chopping the v band off and welding it onto an old stock v band tube. Buyer beware!

Justin, This down-pipe is specifically used for individuals with a aftermarket turbo that requires an HX40 turbo flange and the turbo mounted in the factory location on a 89-93 5.9L truck. We have not had fitment issues with this down-pipe. Next time, let us know if you are running into issues that way we have a chance to fix it for you. If there is anything I can help you out with in the future let us know.

Thank you for the review. Agreed, Diamond Eye does an excellent job with all of their exhaust products. Not many offer an HX40 downpipe for 1st Gens, so this was a nice addition when they began building and offering it.

Is this a stainless steel downpipe? If not, are they available??

This is an aluminized pipe. I do not currently sell any HX40 stainless steel downpipes for the first generation trucks.

Will this work with a borg warner s300sxe turbo. I've read a few things saying an hx40 down pipe is what you need but would like to be sure before placing my order?

No. Most SXE turbos feature a s300 Full Marmon flange unless machined down

will this mate up to a Hole Set 351CW ??

This would not, this is intended to connect only to the HX40 flanges. -AW

Will this fit a stock turbo on a 1990 no ic cummins? H1C??

This will not fit the factory turbo. It is made to work with aftermarket turbo's that have the HX40 outlet flange. This one is made to be a direct replacement for a 4wd. https://www.dieselpowerproducts.com/p-5661-diamond-eye-4-aluminized-turbo-back-exhaust-89-93-59l-dodge-cummins-4wd-k4211a.aspx Let us know if you have any other questions, thank you for your inquiry.

Hey I'm about to order your diamond eye hx40 style 1st gen down pipe and I'm wonder what size is the outlet of the pipe? I'm think its a 4" but don't see that listed anywhere on the product page. Waiting for a response so I can hit order on a exhaust system kit as well.?

The HX40 outlet measures just over 4" and is designed to work ONLY with the HX40 style flange. -Ben
