5Zigen is currently developing a mid-pipe that will produce more top-end power for your celicas. This will be an off-road use only or racing purpose only product. I will keep you updated on the progress of this project.
Yes, give more details about the pipe. But in my opinion we need help in the low end. I have a Hi-Flow cat with 2.5" mid pipe and had pretty good high end but lost low end big time. I just reduced the size to 2.25 and I am already noticing a dramatic change in my low end.
This pipe that they are developing are designed mainly to match their full exhaust. If you recall the review on exhaust, 5Zigen showed less horsepower on the over-all power gain. But, if a person that knows performance looks at the chart, He/She will notice that 5Zigen produced the most mid range power, which is important in road racing or circuit racing when getting out of a turn.

Sounds like a good exhaust for that kind of racer. I myself am a track/drag racer.
