At 45°F ans Sunny I almost wore my shorts to lunch.

Oh boy, just bought a set of pulse matched headers for the 928. The headers that are currently available except for this set are long runner and not equal length pulse matched.

Now do I have a good muffler shop fab me up and x-pipe, or get the Y-pipe cats and borla muffler the guy has.
2 owners ago my car had these headers with Y-pipe and single 4 inch exhaust. With only an adjustable fuel pressure regulator it dynoed 400rwhp.
The last owner put it back to the stock exhaust to pass emissions in Ohio.
