It would have been nice to have the Decibel difference or at least what they are now revving at 4000rpm ? As many racetrack forbid over a certain decibel level Ex: 94DB . A dyno chart would be great to see. Congrats, Looks Great, Fabrication quality seems really good and it does sounds amazing!
I noticed that when test driving the Fabspeed Exhaust for comparison, you kept the revs just below 5K RPM... What gives?? These flat six engines don't get exciting until about 5200 rpm, in my experience. I have an 02, 3.2 liter 986 Boxster S with Fabspeed Exhaust, headers (no cats) CAI, IPD Plenum, throttle body, etc. and it sounds absolutely vicious... Luv it, might even go with Fabspeeds "spec boxster" Exhaust next.
Call me crazy, but that x-pipe doesn't scavenge in that orientation. It's just adding back-pressure making each bank fight with the other and causing a raspy noise while making less power. Cool project though 👍
It sounds more like the last of the aircooled 911`s with this exhaust. those had more of that raspy goodness in their exhaust tone from the factory. I like it that way. But the K-swap is where its really at for me, bring it on! (you might want to consider having a chat with Taylor Ray about turbo K-series and stock connection rods breaking... since he nearly burnt his Cefiro to the ground on its first trackday after a wild engine explosion..)
So I noticed you made an actual x pipe vs fabspeeds which to me looks more like a connecting pipe vs a crossover. I'm not sure I have seen in it person or the inside of one. I'm curious about the sound difference in person? Did you have drone
I have a o2 simulator you can have. It can do 2 post cat sensors. It's a little computer chip that sends a varying voltage back to the computer and make the ecu believe the converters are doing a very good job
