Group buy for Doug Thorley PREMIUM VERSION headers, need 20 people!

I paid yesterday as well. My 4Runner sounds horrible with the ticking, let’s try and get everyone paid so these can start being produced!
 
Pay up people, I need my headers

:whipping2:

Lol, thanks funny. Anyone else that wants in on this, reply here. Remember, after all 20 are paid up (see first page), there will only be a 5 day window for new people to get in on this!
 
How are you guys getting ahold of Jason? I left a call back message on Monday the 12th, called 4 times over the last week and a half, and just left another message 10 minutes ago.

Text him. He's replied every time to me and if you have questions, just say "hey, gotta question. Can you give me a call when you're free" and he does. Very knowledgeable and helpful.


If you're on the list, hurry up and go return your empties and Pay Up!



.....I should start spraying the manifold bolts now with PB Blaster...
 
I'm ready to order, I was able to text him on Monday and get a good idea of how this works, and then texted him on Wednesday without response. Haven't heard from him since Monday.

I'm planning on moving to Denver and I read that Denver and surrounding counties have emission tests. Jason said he sold Long Tubes to a handful of guys in Colorado, does anybody know the situation in Colorado regarding emissions?
 
14 people paid so far!!! Once we get to 20 people paid the production can start, then remember, once we get 20 paid, 5 day window for anyone new to get in on the deal. Doesn't matter if we get 30 people, you'll only have 5 days to get in on this as soon as I announce on here that all 20 are paid up :guitar3:

Oh, and got a new phone and had to restore mine and lost some messages so anyone just text me now at 717-319-2100. I'm still here and alive :)
 
Question for exhaust nerds:

The collector diameter for the short tubes are 2.5", the long tubes are only 2.25".

If I supercharge my truck in the future will I regret getting the long tubes w/ smaller diameter? It seems that boosted vehicles benefit greatly from larger exhaust tubing.

I'm looking to weld an entire new exhaust so if I go with the 2.5" I can do 2.5" throughout the system. If I go with the 2.25" headers I would likely need 2.25" throughout.

[MENTION=164634]Snoopy[/MENTION]_gx470 on insta has a supercharger and headers. might want to check with him and see what he is running

He's got the short tubes. But he might have had them before the LT's came out. He mentioned the LT vs ST debate in a post but not the collector diameter. Nobody has mentioned it that I know of. I just emailed Doug Thorley for their input.
 
Shouldn’t be a problem. He’s got both and SC and long tubes and y pipe

Nice pic.

I don't think 2.25" will be a problem, way better than factory, it just comes down to which is better. 2.25" must match the factory y pipe diameter so that is why they used it on the long tubes. Wheras on the short tubes they don't have a flange so they could get away with the 2.5".

Any idea on the steering shaft clearance with a body lift on the long tubes? People have had issues with the short tubes and we talked about fixing that that on the phone with a dent and shorter bolt, do you think the same thing is needed?

I spoke to Mike Johnson at DT about the clearance of short tubes vs long tubes. He indicated that the long tubes would have better clearance.

I’m paying the difference for the fully SS longtubes to replace mine.

I have a body lift and the short tubes just clear. For some reason when I back up it rubs slightly. Other than that it is good. I’ve shaved down one of my steering mid shaft bolts for clearance. I never tried or even thought of smashing my new headers!

Judging by pics they look like they are thinner around the steering shaft area. We'll know for sure after you get yours.

I think I'm still on board with the long tubes, I can cut the flanges off and weld on new ones 1/4" back where it starts to neck down from a larger diameter.
