FD / Fister Exhaust Recommendation and install guide
Team
After a lot of research - I went with the Fister / FD Motorsports “sport exhaust” (professional gundo) and did the core exchange.
10/10 happy with the result. I am an 07 C4S Cab 6-speed. Sounds is perfect. In my opinion - it’s OEM++ if Porsche sport exhaust (PSE) is OEM+.
Sound: very mechanical. Only noisy when you want it to be - under aggressive load. No drone. Cruising in town and on freeway - can’t tell difference from stock. Sound is less raspy than OEM and is best described by me as unmistakably Porsche, mechanical and perfect level of loud.
Install: once I actually figured out what is needed and not needed - easy as hell. ChaptGPT and Claude both had be doing like 30 extra steps (with good intent). I think they thought I was installing a full system.
My install experience and guide:
No need to remove rear bumper OR rear wheels
No need to remove any body or panels or heat shields
Process: jack up your car safely. If you don’t know hot to do it safely, don’t do this project,
I jacked up the rear only - stands on lowest setting.
I used a lot of PB blaster - but I am also a 17k mile southern car.your mileage may vary.
To get the mufflers OUT - it’s only 6 total bolts.
- 2 bolts connecting the rear muffler section to the mid-pipe. 13mm - right next to each other, muffler clamp style. That’s 2. Then - I went into the inner fender at the bottom near the wheel and removed the bar that keeps / holds the rear bumper in place. It’s a torx / star bit, right behind the rear wheel. Just remove the bottom (not the top connected to chassis). This is the third bolt.
Here is where I was initially mislead. The last 3 bolts are actually all on the side / inside of the mufflers. The muffler is mounted sort of vertical. There are R bolts (again 13mm) on the SIDE of the muffler (on the inside, near the engine side. They are not going up and down - rather sideways, connecting a crack to the muffler. Remove these and then the mufflers will Tetris / jenga their way out.
Once out of the car - there are 3 more bolts. Two 13mm that connect the muffler to the bracket - you’ll need a wrench 13mm and a 13mm socket, easy once the mufflers are out. Then you’ll need to remove the exhaust tips (also 13mm) and move to your new exhaust.
Install is reverse.
6 total bolts. 3 in the side of the muffler holding the bracket to the muffler, 2 at the back connecting to the mid pipe and 1 to help give you space with the bar that holds the rear bumper in place.
No shit - once you get the car in the air safely, I estimate the TOTAL install on both sides at one hour.
Highly highly recommend Fister / FD. Darrin is awesome, quality is great, sound is perfect for a daily or weekend fun car.
