hi , have overfinch which needs new exhaust down pipes ( headers ) for the 5 Ltr chevy engine thats fitted ,some people say that the pipes were made for overfinch , but i am not sure , has any one got any ideas ???
best route is to go to a custom exhaust place like powerflow or longlife, they will make you a replacement in stainless steel at a fraction of what Overfinch will charge.
Plus, they give a lifetime warrenty on their parts.
You have probably sorted it by now ...but .... FYI
I have an overfinch disco - the original cast headers always cracked (I believe due to conversion to unleaded fuel) - finally tracked down a set from a corvette specialist in east london.
spent a fortune on a custom S/S set but have had to stop project due to lack of time and money :-( ..
