very high quality product from PPE . it made a good sound difference from old one and i noticed my egt's dropped a small amount. if your going to go with a down pipe i dont see why you need to go with any other product its at a good price and made with stainless steel and heat wrap. plus made in america what more can you ask for
great part

This is by far the best priced stainless down pipe out there. Very good looking welds and the heat wrap is top notch. Also, XDP has the fastest shipping ever!!!
