I am looking at the LRD and the DASA pipes. I am looking for great performance but also want a quieter pipe if possible. I have read that the LRD pipe is only 92.5 db with the spark arrester in and 96 with it out. Is this comparable to the stock pipe or does it sound much louder? I also looked through the forum and found some dyno charts and there it is stated that the DASA is 100db. Does anyone know if this is with the spark arrester in or out? I guess my main question is witch pipe performance the best and yet keep the noise level down as much as possible? I do a lot of mountain riding and a quite pipe would be great. Also are there any other pipes I should look at?
