However my car is still pretty quiet...I'd guess they make very little difference in sound if you're still using the stock cats.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Have anyone used a set of GHL headers? It seems that their design is different than many others and I wanted to know the quality of GHL. Will there be any improvement in performance? Will there be any difference in sounds?
That's indeed an interesting design; different to the stock or other equal lenght headers.
I went with cheap e-bay headers for $200 which I found to have the same design and characteristics than more expensive e.g. Fabspeed headers. Quality of headers and gaskets appears very good; weight almost the same as stock headers.
In combination with my GHL mufflers, the sound experience did improve with the headers. I've now already at low RPM a very nice exhaust tone. Performance wise I feel that I lost low end torque (<3k RPM); more push at high end.
I already have low expectation for N/A cars in general. Is the sound significantly different? My car have the GHL muffler right now and is fairly quiet.
I have the GHL sport exhaust along with Carrera Sport Headers sold by Suncost Porsche and I love the sound and my Butt Dyno reads a power gain of 19 � HP but, it is at the higher RPM range.
I have GHL headers and mufflers on my car...however they were already present when I bought it so I can't give you a before and after difference.
However my car is still pretty quiet...I'd guess they make very little difference in sound if you're still using the stock cats.
