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.

Does anyone have dynos after adding B&B Headers and Mufflers as their only mod? Interested in seeing if they really add horsepower. I have an 03 996 that I am thinking about adding these to. Would headers and mufflers void warranties? I tried searching for this info and couldn't find it after an hour of searching. Any help appreciated.
Don't know about dyno sheets, but member mfletch had bill boat headers on his MKI and loved them.
I've driven Mark's (Mtfletch) car with the Billy Boats, and it has a great sound.....but then I also drove a 996TT with the BB's and they resonated so badly I told the fellow that I wouldn't buy the car with them in it. I just went to the Europipe website, and they have a chart that shows all the decibel (db) ratings for their product lines at different RPM's measured both inside and outside the car. You might ask the BB parent company if they have the same sort of info available....just a thought.
