UPDATE!

Alright so before it started raining today. I picked up a datalogger and the whole setup. Ended up finding the exhaust gasket I need (went through 3 Discount Auto Part Stores and they didn't have it)... ended up going to Lokey Mitsubishi off Gulf to Bay and they had it. Put the downpipe, extension and test pipe in with all new gaskets. Initialized my SAFC and did the inital setup. Ran the MMC program on the datalogger. Started the car up... sounds nice... then I felt around found 1 exhaust leak... tighted the bolt up more... no more leak! Then it started to rain... tomorrow if the weather permits I'll start tuning and changing the settings on the AFC. It was idling where it should idle and no wierd noises
