Brian, is there a computer flasher/tuner you can buy for the Fiesta yet? The reason people lose low end power is because increasing exhaust size leans the engine. The lower restriction lets the engine pump more air, and the computer cannot compensate completely for big changes to the exhaust.
If you get a new program for the engine, then the program can be made for a bigger exhaust, thus no loss of low end power.
No kidding? I didnt know that...but there arent any yet, and I say yet because I believe theres a petition to get one from SCT.
Yep, here it is:
