Ultimate Racing Test Pipe
Ultimate Racing Test Pipe
Just thought I would offer up my review of the Ultimate Racing 3-inch test pipe which I purchased from Z-1 performance. I installed mine last week and wow what a difference. The car pulls much harder through all gears, especially in first and second. It bolted right up to the stock dp and to my HKS catback. Wire extensions, gaskets and hardware are all included. After easy driving and rallying the hell out of my evo in warm/cold weather I have no CEL's. If your looking for a test pipe, check these out at Z-1 performance, great product and customer service 
Is Idaho a no emitions state or are you just pulling a switch-a-rooney on emitions testing ? I was looking at getting a down pipe but haven't checked to see if AZ is a emitions free state.
