My last post didn't really convey the message I was trying to put out. Bassani exhaust and all these other systems are nice and very expensive, but I'm just trying to say they still don't allow the duratec to exhale enough. The power gains I got were a slap across the face. Once the computer calibrated that there was no longer a sock in it's mouth, and now three inch pipe to put out all that exhaust, the power is amazing. I'm sure were talking about 11 to 14 hp gains. The engine doesn't put out power through winding up or after 3200 - 3400 rpms, it's now very consistent. If you're about 16 or 19 years of age (I'm 18), go to highschool and could care less what others think, this may be the cheap mod for you. I only paid $170, not $1000, and my car now sounds like a Subaru rally car or a 5.0 running straight pipes. Best of all, NO RASSSNNNHHHSP. This system requires no mufflers, just the stock tips and a flowmaster Y-pipe. I will post pictures later and try to get a Dyno as soon as possible. I don't have a chip, just a K&N filter. K&N filters are bad by the way. They release fibers that get caught in the MAF and burn it out.
