Did the the rotrex car you drove at the track have the OEM header and exhaust? I wonder if the OEM catback will provide adequate flow since I'd much rather keep the OEM catback for sound and cost purposes and I am definitely not worried about 3-5 whp that I can gain with that. I will most likely change the OF/FP combo only.
Thanks again

Yes the JR kit cars have both OEM cats, and have a 100% OEM exhaust system. If you get a custom tune with a non-catted header and non-catted front pipe, I'd expect to see a large HP increase. With E85/race gas, even more.
