Default Best headers / exhaust combination

I have a set of GHL headers / exhaust on our car. These were installed on the car when we brought her home. Subjectively, the car sounds a bit anemic by modern standards and it may be that I've grown accustomed to higher revving motors, but I wanted to know if there is a system(s) that people recommend. Also any appreciable performance gains apart from sound? Thanks.

Not a fan of GHL myself. Particularly I would stick with stock headers unless you are doing a full build. A simple cat delete or 100 cell cat and a simple magniflow and chip will give you great sound and decent performance. If you want more sound a cup style airbox and 4" Dansk tip. I haven't found many claims to be worth the expense otherwise. IMO.

I concur, although there is a bit of drone around 3000rpm on the highway. Not a problem once you get past 115km/h (70mph)

OP, your username is familiar to me. You wouldn't happen to have been in the GM / LS world in a past life?

Thanks for all the input. Perhaps sticking with current set up or going back to stock makes sense...

Does anyone know how the Fabspeed headers compare to the B&B headers that Rennline carries? Thanks,

Our systems are hand welded here in the states, and have been a center piece of what Fabspeed represents for many years. We developed these headers almost 30 years ago, in efforts to wake up the older Carrera's with bolt on system that wont trigger lights.

I’m already sold on Fabspeed, and love the sport cats in my 993. But seriously, can anyone provide an objective comparison?

I did so much to mine when I had it built so I cant tell you an objective comparison but I will say that my RSR dual outlet setup is great. Wife dosen't complain about loudness.

Fabspeed’s exhaust is junk. If you’ve got the money for theirs, then you should be able to spend an extra grand and buy the best that’s made buy M&M in Germany and used by the factory race teams.
Segmented Welded, not mandrel bent. Best money can buy.
Our primary tubing is segmented and welded under pressure with the use of forming gas. Forming gas actually pressurizes the area being welded to create a smooth inner surface. This means that material walls in the bend are consistent and strong, ensuring reliability. But we don’t stop there, once the segmenting is completed, a tool is passed inside the header, which will actually grinds away any left-over slag. This process produces extremely durable headers with superior strength that ensures higher gas velocity and less exhaust gas restriction.”
