Here is the Hpi ss cut at the mid band and extended for more low to mid range. This extension gives it almost 4" more which puts the mid band length close to the DOM.

I have started a aditional weld before it breaks at the flange (as of hellya header). The HPI header is very poor aluminum material. the previous ones are welcome to send it back to me for this additional weld. I will do it free of charge. I however cannot cover shipping so you may want to do it when getting another part.satttheman said:if ur running the hpi ss pipe on ur rampage you want the extended band it was a night and day differences. i wish i couldve made a vid before the header broke at the flange no big deal my friends goin to fix it sunday. im also goin to try the stock gearing and see how it does ive been running 30/30 i would how much more bottom end power will i have with the stock gearing. ive seen hellya vid and his rips with the 23 and the dom withs tock gearing thats how mines rips now after the extension and the 30/30 gearing
