Hi Guys,
I'm using 421 extractor with 2" piping and stainless steel straightflow muffler. Piping route follow the original one. Both the flexible and the center "tabung" still installed. But the sound is still a bit loud to me. Can i fix one more "tabung" to slower down the sound? Will this affect the performance? Or what should I do to reduce the sound other than put back the original piping? Pls help. Thank you
