I finally got some 3" 3 chamber flowmasters on my car and got rid of the one chambers and it is almost quiet, it sounds so much better and I can even hear the radio again.
The 1 chamber flows were cool at first but get real old real quick.
The exhaust system is long tube headers and 3" Dr. gas X-pipe and 3" 3 chamber flowmasters with the delta flow technology and I still have the turndowns.
Anyway just thought I would share!
