The ARP 5 pack stainless length is simply amazing! The exhaust system upgrade provides my automotive with a noticeable increase in power, as well as an aggressive sound .Based on my observations, it appears to be made with high-quality materials, which is a huge plus. The installation process was straightforward and hassle-free. The only downside is the price, which is on the higher end but it`s worth every penny spent. Overall, I highly recommend this product to anyone looking for a top-notch exhaust system upgrade..
