Hello fellow nc enthusiasts. Have owned nc750s for approx three months, am wondering is anyone aware of a quieter slip on exhaust than the stock exhaust? I know its already a quiet bike however, just wondering have done a few google searches and couldn't find anything. I previously owned a CBR 500r and the thing was quieter than a bicycle at idle, which was great for me as I like keep quiet on early morning commutes. The nc seems more thuddier than the cbr at idle, perhaps the bigger engine? Both being twins. Thanks in advance. Safe Riding. ATGATT.
