Don't forget to rub it down every now and then. 
The exhaust parts finally arrived. Two dissassembled 12A header kits and the RB dual pipe center section. Each 180° pair of rotors will receive a short primary system, collected at RB's recommended 10" to 18". The inner diameter will be 1.8" (Standard RB pipe) rather than their recommended 1.9 to 2.0. This is not a problem though as the engine will not be expected to run to the outer limits. A practical RPM limit of 8k is fine. Modest peripheral ports should allow for some street driveability. The HP will still be in excess of 400, which in a 1st gen, is probably the limit of tractibility. This won't be a drag car. It needs to retain some reasonable handling ability for the twisties, through which it will be driven more often than stop and go straight-lineness.

Its my pleasure, really
There is one problem though, apparently the two intermediate housings were in the factory mazda boxes and the two boxes were taped together...so they were shipped as "one package" and guess what happened in shipping? Yep, the boxes came apart and I only recieved one box. So somewhere between my house and Jeffs shop is my center housing and hopefully FedEx will be able to find it, but something tells me that is not going to happen. But I will keep you posted
