Group Buy for DT headers 200 series (1 Viewer)

[aznxfactor]

Does anyone have Dyno sheets showing the gains of the short and long versions? This seems to good to be true. Do they offer a solution to prevent the CEL if going with the long version?

The short is supposed to not get the CEL on.

Keep in mind if you get the long version that the cel will go on without tuning and you have to get a new exhaust system.

IMO get the short because the 200 series isn't a tundra. So we don't have a lot of solutions. If you owned a tundra than get the long tube because tundra sales is like jeeps so therefore there are thousands of aftermarket solutions.

200 series owner are an extremely small niche. Personally for me, I'm at the point to where I love my 2016 200 series and plan to keep for 30+ years. Probably til God tells me it's time. Im gonna mod the f#@!& out of it because if it breaks or fails, which I highly doubt than it gives me a reason to get a 300 series.
I'm literally challenging my 200 series to fail on me. Only reason I'm doing that is because I keep challenging my tundra at 198k to fail and it doesn't fail so im like, let's go!

Plus we don't have enough data on performance mods on 200 series because the people prior just doesn't want to mod it, so im breaking the mold as a 37 y/o turning 38 to find out all mods outside of a supercharger and regearing.

Let's face it 200 series outside the US is cool cuz the mode and tune the kino twin turbo v8 and we don't.

let's change that!

I have modified quite a few cars and in the process have learned that making big power from a single modification isn't super likely on a single modification (especially with Naturally Aspirated cars). I have had some cars that have gained a worthwhile bit of power (at the wheels) off of headers and had cars that made little to no power increase with changing headers.

A long tube setup is typically going to make more power, so if I am going to do this I would rather go the long tube route. Making a custom exhaust to match isn't an issue. My concern would be eliminating the CEL (can be typically done by moving the O2 sensor further away from the exhaust stream, but I would prefer a harness that goes on the O2 to remove the light) and making sure the stock tune can handle the change of headers without a tune hopefully.

I don't believe in modding things without backup data demonstrating it being worthwhile. I wouldn't want to go through all this trouble to barely pick up any wheel HP and TQ. Hopefully somebody shows up with a dyno sheet showing where and what the gains are. If the data isn't available now, I hope one of you all who bought these would spend the $50 or so to get your vehicle dynoed.

I would like to know the power gains for the "shorty" header please

Ok so I got it installed today at my buddies shop. My dealership won't do it because they don't want to mess with it. Oh well.

First thing's first:
1. I'm told it's a pain to install because of all the tight spaces.
2. You will need to grind down the steering rack bolt and parts around it as it will grind on the headers and you will feel it when you turn all the way left.

I attached a photo. Hopefully it can be clearly seen.


So far from what I noticed with no tune on the 8-Speed:
I didnt really hear anything noticeable when I turned it on or even drove at low rpm and speed. (Kinda felt sad as everyone on the tundra side said you feel low to middle end gains.)

However once I got on the feeder roads under neath the highway, I started to punch it. Here's what I noticed:
1. The middle end and high end torque punch is hard between gear shifting.
2. The sound starts to open up in the middle rpms.
3. With windows down you start to hear large swooshes of air flowing in the middle rpms when i punched it.

Now keep in mind, I've only driven it like 5 miles total so far as I had to drive to work in my rcf and it was at my buddy's shop. Im about to bring it home tonight and drive around a bit to get better feedback.

So far I like it. Here is a pic of what had to be grinded down in order for it to steer without rubbing.

Bump for reminder that the offer ends at the end of this month.

You guys know you can buy the short and long tube.

Whats the power gains on the shorty???

Whats the power gains on the shorty???

It's $100 bucks for the dyno.
I just jumped on the tundra group buy for dirty deeds exhaust and ordered one for the 200 series.

I might wait to get dyno after installation of exhaust... not sure.

Here is a thread from a cali tundra guy installing DT shorts.

DT shorty headers

What do you guys think.. [ATTACH] [ATTACH] [ATTACH] [ATTACH]

After reading it, im going to disconnect my battery as well.

And yes they do have antagonist stating that the stock manifolds are perfect but also some good facts on why the aftermarket is just as good.

I'm happy with it and I will disconnect my battery and drive 100 miles. I haven't been as I've been driving my tundra lately...

realized I didn't post the thread.

Just updated it..

Bump. Did we figure out any power gains?

Nothing dynoed but I can feel the difference. Haha

Probably needs a dyno at some point

Did anyone do the long tubes? Did anyone notice a difference between the two?

 

[Dustin Ridgway]

Did this happen? I would be interested in a pair as well.

 

[aznxfactor]

I set up the group buy a while back but not sure of the results. I bought two for each my land cruiser and crewmax tundra.

Another group buy would be nice @dirtydeeds

 

[sreyes1103]

Any idea on the discount and how many needed to get that discount? Interested.

Does any know if this will work on a 2021 LX?

 

[aznxfactor]

Will work on 5.7 v8s

Right on, reason I asked was because it only shows up to 2018 model year LC.

I can't speak for that as I live in Texas however if you look at my post there is grinding due to the small space compared to the tundra. Had to grind the steering shaft to fit.
