post 3 for this car with catted header back exhaust. One of the very last posts, Jason has the graph comparing the 3 different header designs against eachother and against stock:

The catted header design felt the best down low and helped improve the torque dip to the point that I didn't really care about it any more. The catless has less of those gains down low, but more gains up top- probably better for a track vehicle. It's also louder, obviously.
The axleback I'm running is the nameless with 6" custom made mufflers, that's $550. The downpipe I'm running is a high flow catted design, with the overpipe integrated into it in one piece, so less flanges, less weight, and replaces 2 pipes. I believe that's 500, with cat. The downpipe and axleback by themselves made 11whp across the board with 19whp up past 6500rpm. Add the headers in there, and it goes up to 19whp across the board with up to 25-29whp gain above 6500rpm.
Overall, massive gains. But the car seemed to baseline a little lower than some other cars, so I'd love to see these parts on one of those cars that managed to baseline 165 or 170 whp. I think Drift Office's FR-S is at 167 stock. Man, with these parts, he'd be up near 186 peak whp. that'd be cool to see.
