Banks makes long tubes. The only problem is they are for Motorhomes and I think they are too long to fit in a SD.
I don't know if you'll be able to tell any difference between long tubes and shorties.
The Thorley's are probably the closest to long tubes that will fit.
How are those Thorley's holding up Antelope?

These shorties usually keep the low end the same or hurt it a bit...but will be felt on the high RPM's. So...the long tubes would just be the opposite...IMO.

I can definitely tell the difference. But once I get on it, no different.
Of course, there is more noise in the cab, coming from the headers themselves. Gotta get some insulation installed in the floor

The graph Thorley sent me shows a H.P. gain of 26.4 and a Torque gain of 40ft.lbs.
I looked up JBA, they show 38H.P. and Torque 73 ft.lbs over stock.
Banks shows 49.2 H.P. and Torque 58.7 ft.lbs over stock. This of course is with their full Power Pack minus the Ottomind.
I would like to see a dyno run of shorties {JBA, Gibson} with a Stan's or E-bay Y-Pipe mod.
Others have mentioned the Ford Racing headers. If you go that route, I do believe they are NOT smog legal if you have that in your state.

The numbers are not HP and Torque gains at PEAK HP and TQ as they would like you to believe.
You may (but I doubt it) get 73ft.lbs more torque over stock with the JBA headers, however that may be at 5400rpm, when the peak torque is around 3200rpm. HP numbers are similar too.
I'm not trying to attack you or your post Antelope. Just trying to put the manufacturers claims into perspective.

No biggy dkf. All 3 mfg. I mentioned have dyno graphs available to see at their respective websites. I tend to believe them just for hoots I guess. The JBA Dodge v-10 headers show an increase of 15 H.P. and 16.08 ft.lbs of Torque over stock. Not much of an increase. I guess my point is they could have made up some real big numbers to sell headers if they wanted to. Personally I wouldn't go to all the trouble for those low numbers.

When we were still naturally aspirated, only slightly modified, we ran shorties to keep the torque numbers up. Long tubes on a lightly modded V8 made it a dog off the line. But I don't know, maybe this V10 is just a different animal.
