Calling all V8 owners that want a high flow Y-pipe!!! I can do it. Need your help!

[Jason B]

For short tubes (since they need welding) what he said above it all correct ^^^

For the new Long tubes will be less, 7-8 hours. Y-pipe is probs 1-2.

Thank you Jason B for hooking me up with the Updated 03-04 Y-pipe. Be here Thursday.

 

[Az4runnin]

Y-pipe is Here

Cant wait to install. Thanks [MENTION=9]Jason B[/MENTION]. Stoked. Sunday most likely for install.

 

[Az4runnin]

Looks very Nice.

 

[Az4runnin]

Out with the Old

 

[Az4runnin]

In with the New. No hangin below cross member.

Did they redo the design? I got one of the first ones they made and it’s literally no better then the stock one for clearance.

Edit: looks like they did from the pics. 3 pieces now and it’s definitely higher clearance. Crappy for us first batch buyers, specially since I made it abundantly clear my only reason for this was clearance and after install complained it has zero more clearance and didn’t receive any response.

Yes they Did redesign it. They brought it Higher Up for just that reason.

[MENTION=9]Jason B[/MENTION] anything you can do for us first batch guys who you promised the pipe had higher clearance and it didn’t? My pipe rattles insane on my RCI skid even with spacers.

Do you know how recently they (DT) started shipping the redesign to distributors?

DT just started Shipping last Monday. I had been in Constant communication with Jason because I needed it ASAP.

Dang. Ordered Tuesday from URD and their batch got to them a couple of weeks ago..

UDATE/EDIT: So, just got off the phone with DT.

They were only seeing fitment issues on the 03-04 models where the crossover was hanging too low.

They have a new pipe for those years. The original pipe design should not hang too low on the 05-09 model 4Rs.

 

[Jason B]

New pipe looks great. Call or text to order form me here 717-319-2100

 

[Brian3676]

Take that as a no then. Bummer. Simply being acknowledged with a no would be better then ignored.

 

[JONBOY345]

Couple shots of the fitment on my 09 V8.

Note that I have an aftermarket cat-back with an additional resonator between the muffler and the flange connecting to the y-pipe. The location/angle of that pipe is close to stock, but not exact. If you have a stock cat-back exhaust, it's possible it may fit up higher under the truck. I'm not running skids, but from looking online I think I'll be okay when I add them later by running a couple spacers.

The pipe is hanging about 3/4" below the cross member, not great but not bad either.

I'll get around to creating a video eventually. Have a drive at the end of the week that I made 2 weeks ago. Looking forward to see if I pick up an MPG or two.

 

[Jason B]

Thanks for the pics, and posts. I don't always see all the replies here. When I get an email notification and I'm in a rush I reply but again sometimes miss other posts.

If you have a fitment issue or question for the 03-04 Y pipe, call Doug thorley at 800-347-8664. Ask for MIKE and tell him Jason sent you and he will go over it with you, etc. and will help.

Also, if anyone needs a Y pipe, call or text me at 717-319-2100 to order, etc.

Yesterday I ordered this from Jason, a new build thread to be born.

Any notice in performance gains? Butt dyno, MPG, etc. from these new y-pipes?

That's what I was afraid of with this question … silence.
Why go thru the aggravation if there is no measurable benefit?

@%1;

I can tell the difference on start up. Truck roars to life with a very deep growl. Butt dynos are subjective, but I feel at between 3k and 4500 rpms it pulls better. The problem with any expectations of measurable power gains is it costs money to tune and dyno. We are the first ones to put these on our trucks. DT has been producing headers since the 1960s, so I think they have a pretty good idea how exhaust flow works. Looking at a cross section of the OEM crossover tells me that my engine will breath a whole lot better. Is this enough juice for the average person to go through all the aggravation and expense? Not for most. We don't have the luxury of dozens of performance aftermarket parts being produced and tested like say a small block Chevy or Ford. We do these mods in the hopes that our soccer mom SUVs will gain some punch. Toyota performance costs money unfortunately. If someone wants to donate a stock V8, do a baseline dyno run, put 33 to 35 inch tires on it and do another dyno run, put intake on, tune and dyno again, put exhaust on, tune and dyno again, we would have concrete numbers to advertise for these products. You see the logistical and financial problems this would present for most of us? Hell lets put a go fund me account together, buy a truck and donate it to DT and let them experiment for awhile. Even then there is not enough interest for DT to put much R&D into a project like this. These pipes make power, but until some real world proven numbers are published, there will always be people who disagree that they make any power at all. I'm sure someone will disagree with this post as it is. There would be people who disagree with actual dyno numbers being accurate. This is not like an interior led swap where you can take a picture and show everybody. It's a leap of faith I was willing to take and have been happy I did.
