i will be the first to admit that my bias is probably purely in my head.. ijust tend to trust a company like say DC to fabricate a way more efficent piping system then some guys ina muffler shop.. there are LOTS of things i will cut corners on.. but this was something i did not.. i went with a cat back apex kit.. super durable sounds decent and im just confident its quality NOT sayign you won't get something good.. just saying that i would trust someone with more R&D money and time into OUR specific needs..
