Just installed my borla catback and I was wanting some opinions on which plate to use.. I have the tuneable system.. I now have the wide open plate in and I was wondering if one of the other plates would give me a deeper sound.. There is a fully closed plate and a fully open plate with 2 different sized plates in between.. give me your opinion. my car is a 99' ss

 

also if you go with the fully closed plate is there any horsepower loss?? thanks

I had the borla adjustable, and i didnt notice an difference between the smallest to the largest plate.....

 

Here's a link to a movie that might give you some idea of what it sounds like adjusting the Borla. Gonzo has an electric motor (same one I got) that opens/closes the right side of his system. He has a bit more work done to his car though. As far as the plates go, I've only run the closed and wide open plates on my system before I moved to the electric motor (in anticipation of headers...which hasn't happened yet ). Personally, I don't think it affects the tone a whole lot. It's more volume controll. As for power differences...you might see a small difference, but nothing major. Hope that helps some...
