Been a bit of discussion about stainless steel manifolds and full systems. I have had a straight through system on A666 for 10 years, works a treat, never touched it. A member on here, Simon works with stainless all the time. He is the brother of Mat, who are both helping me with A69. Top class workmanship. I spoke to Simon this morning and he is more than willing in to fabricate and tig systems to order. The only drawback maybe availability of bends and tube in this present debacle. Give him a ring on 07852 612652 for a chat about what you may need. Paul.
