Works good but needed tweaking to get to fit 100%corretly Required grind ton the inside because of the casting flaws

These up pipes were a great deal! They fit great and lined up perfectly with my turbo the only issue was there was only one gasket but the part store was able to match one. Overall great product

The pipes the design,an the hardware were all good an met expectations. The cast why peace as you can see in the pictures has an alignment pin so that the ports line up with the turbo ports. The alignment pin as you can see in the pictures is off just enough that when you get the PIN to go in to the turbo side it will not sit flat thus you can't get the clamp on and it's very hard to tell and see what's going on when you're installing it due to the positioning of the turbo you're right up against the firewall so after I figured out that there's something wrong I pulled the turbo off put the two pieces together and noticed that it was not sitting correct an the ports were misaligned severely so begin to inspect the y-pipe and noticed that the PIN was off center.Try to contact Amazon to do a return and maybe overnight the part because I need my truck for work cannot be down for multiple days after figuring out that it wouldn't get here until the 30th and we're on the 26th. I'm an experienced automotive technician, have dealt with similar situations so I had the knowledge and the tooling to correct this making sure that pin was incorrect position now I feel like I should get a refund for at least the the cast y-pipe. There is also casting that needed to be removed in the inside of the ports definitely obstructing flow. But it's a piece of cast so that's understandable so I had no problem cleaning it up a bitSo I contact Amazon again and the only way they want it let me get a return is if I ship the parts back for some reason I cannot contact JDM myself I have to go through Amazon so if somebody from JDM could get back to me I processed the return already but do not intend shipping the entire parts back I just want to get reimbursed for the y-pipe I think that's fair given all of the time that was wasted due to a poor quality control this will not stop me from buying parts from you guys usually everything from JDM is quite good I have yet to have any complaints other than this and I run an automotive repair service where Amazon is my main parts source so please somebody get back to me so that we can fix this

So With heavy modifications this will work in your truck. Truck it went on was a 99 f550 with a 7.3l powerstroke. For starters the alignment dowel in the cast y was off by about 1/8". I was able to work with that by grinding the pin down a little. The real main issue here was the up pipes themselves are way too long. I actually had to cut the bellows off both up pipes and shorten both pipes by 3/4" the re weld the bellows onto the up pipes. This was a major process even here at my repair shop. 3rd issue was the one flange was offset wrong on the passenger side at the manifold so you had to open the holes up a little to bolt it on. Over all no way would any of this bolt on with out serious modifications.

2001 f250 7.3LIt fits. Aggravating to install to the turboTips on doing the job.-Remove trans dip stick-remove turbo- leave new up pipes very loose when connecting the collector to turbo. Then tighten up manifold to up pipes and the tighten the up pipe to collector.Everything hurts to sit, lay or lean on in the engine bay. You will be laying leaning and bent over your knees trying to reach the bolt on the collector.The next day I felt like I had put a transmission in a car.

Installed on my 99 7.3 F250SD, it took me all day to get the 20 year old ones out...lol but they eventually came out. I was expecting it not to line up at all with the newly rebuilt and modified turbo and pedestal, I was wrong. I slid it in there in one piece installed in about 5 mins, put the turbo back on and the y pipe dowel pin slid right in and it was flush all around just clamped up and zero leaks so far! Would recommend replacing the y-pipe to turbo clamp, makes an even tighter seal and easier to install.

Bought these to replace my leaking stock uppipes. Over they were good quality. I did have to use my thread chaser kit to clean up the housing bolt holes. They have been on my truck for several months. They have been pretty good this far.

2003 f 250. Casting on collector a bit rough and looked as though it had been tossed around . Had to sand all the mating surfaces and remove big burrs on the inside. Other than that the fit was great.

works good and a lot cheaper then oem
