A very cost effective way to increase sound and power on my 10th gen Si. Added the silver ceramic coating option on the downpipe. Some raspy sound at mid-high rpm on stock exhaust, not too bad. Overall sound is 2 times louder than stock on Si. Louder at between 2000 rpm and 2300 rpm. TSP price including shipping is VERY competitive, actually best price I could find. Very responsive customer service. Highly recommend RV6 products and TSP.
