Just wanted to give a heads up to those thinking of using the oldstyle header and tuned pipe combination from MacsPro. I called them for tech support and had a rather unpleasant conversation with who I believe was the owner of Macs about him stopping production on them, the older style,in lew of the new style black one piece non tuned pipes.
I called for tech support about some trouble I was having with a tuned pipe setup and well he frankly was not very interested in the old stuff. I had recently bought a pretuned setup for a 45 OS and was reading the direction that came in the package and it refered to a propellor I never head of zingali or something like that, I asked the guy if he new where get them and he said we haven't bought any propellors in a long time. I was kinda shocked that here is a company that makes exhaust systems and is not testing any of the product with current propellors.
I have not been happy with this guy and it's a shame cause the product's seemed to be good quality.Of the times I called for tech support and got him he's just been a real jerk. Didn't seem like he wanted to help me out on the older stuff at all. I do understand that he probably wants to sell the new stuff, but if that's the case then he shouldn't offer the old if he can't be bothered with supporting it.
Once I called, he answered, said he was on the other line, took down my name, ph# and even ask for me my zipcode and said he'd call me right back. 40 minutes later I called him back and he didn't even remember taking the call. Horrible tech support.
All I can say is get what you can and preferably not directly from the company as he signed a no discount clause with with his clients and has to charge full retail prices. $130 for a OS 40-45 FSR pre tuned sytsem. At least that's what he told me and charged me. I won't buy from him again and If I can help it won't buy new at all.
This guy is a real piece of work!
