I think that makes 3 of us now that had to modify their Y pipe to fit the DT headers...
Really? I stopped looking at that thread because of how annoyed I was with the wait time. Similar modification required on yours?

I did things a little backwards. I had the DT Y installed before I ever pulled the trigger on the headers. I did not install the Y, but my buddy who owns a pretty reputable repair shop and a built 3rd gen, did the job. He told me they tried every angle and config they could think of, but could not get the Y to match up to the stock driver side manifold. They did a pretty good job on the cut and repo.Yes and [MENTION=119302]4RunnerAquasport[/MENTION] modified his too.

Now fast fwd 10 months and the modified Y won't match up when I installed the headers lol. So it needed to be modified again, and I drove it over to his shop wide open 4.7 hittin the airwaves. I will say his welder does pretty good, and my bud being a T4R fan, helps my wallet with cash deals after close of business. That way his welder gets paid off the books too.
I wonder if I had done this the right way if the DT Y would have matched up to their headers. Now if I want to have CATS put back on, guess what? The Frankenstein Y gets modified.....(Forest Gump voice) AGAIN......
The strange thing is the passenger side matched perfectly with both installs, never had to do anything to it.
I also wondered how much variation of manifold fitment might be across all the different models and years of Yotas that have the 2UZ, and how many cross referenced parts were used over the years.
Hell DT's donor truck (or mine) could have had a drivers side Tundra manifold stuck on there at some point over the years, throwing off the geometry a little.
So I really have no evidence to offer because I was too busy and wasn't there for the initial mod of the DT Y last year, and will never know if it was their fault or not.
Learning the hard way is how it goes, seeking power out of 4Runners lol.
Can't say I'm not happy with how they sound and perform though. I just re-torqued the header bolts after a couple thousand miles and only got an 1/8 to 1/4 turn out of just a few of them. So they're sealed up tight with the gaskets and heads and breaking in pretty well.

Purchasing my interior LEDs from SuperBright as we speak. Install and map-light mod coming up next for me!
