Headers - Long Tube vs Short Tube

been looking at different headers from URD, what do you guys have. Should I go long or short tube? Any regerts with what you have now? Brand?
For a 4.0 v6

 

long tubes are going to make it basically impossible to have cats so if that's an issue that makes it a pretty easy choice, people also have said if you aren't blown you will lose some low end with long tubes. I have shorties on mine but i custom fabbed up a turbo set up so I'm not exactly your run of the mill header guy

 

Only total gains to be had with the URD equal length Spec-U headers.

 

Emissions?
Short tubes.

No emissions? Longtubes

 

My goal for this year is to get it supercharged (magnuson). was hoping to pair it with the URD y pipe, trd intake, and a cat back - not sure which one. Just looking for the highest gains, I could care less about emissions

 

Isnt kernville ca in california? Dont they care about emissions?

 

Also i say go for long tubes if all else is good and ur puttin a blower on it. Basically a factory bolt on replacement with no welding required. Should flow a little better than shorties too i suppose

 

do not use the newer all plastic trd intake, K&N/aem screwed up and it runs lean.
Use the afe stage 2 SI, or the old TRD made by afe
use a 3" exhaust and not a "catback" since ur not woried about emissions it should be paired with longtubes

 

good point tho

 

I just purchased Doug Thorley headers. Silver ceramic. Comes with y-pipe. Got them brand new for $318! Couldn't pass them up for that price. Looking forward to how it will pair with my TRD supercharger. I sent URD pictures of them to make sure everything that came with them was there and the correct fit for my truck. Can't wait to get them on!

 

They do. I don't.

 

Link? That price is amazing

 

Believe it or not. I got the headers off of Amazon.com. But after I ordered them they bumped the price up to $840. I am guessing someone at Amazon had the wrong price up and after I oredered and was sent out they realized they made a mistake on the pricing. Had a friend try to order them after I did. And he found the price was changed.

 

Lucky

 

Yeah, that was not the right price for thorleys.
And they do not come with a ypipe normally, thats a different product itself.
How many bungs per header do they have?

 

Dont worry, Amazon wont ship them to u anyhow. Atleast not longtubes

 

Dick haha,
Damn you California!!!
