Hi guys, Getting a JTG Gas conversion and custom tune soon. In the meantime I am looking at other support mods for reliability and am looking at cooler pipes. The two at my price point (sub $500) are the Herrod & Coolerworx. On the surface they seem virtually the same, black powder coated aluminium, ribbed pipe ends, silicon joiners & spring clamps. I noticed in another thread that Herrods don't allow for 4 inch+ turbo side intakes, is that right? If you guys were doing it which would you choose? And those of you that have done it, which did you choose and why? Cheers, Daniel.
