Upgrading my automotive`s exhaust system has always been a daunting task. However based on my experience with this Straight Through Performance muffler, I couldn't have MADE a better choice. It provides an impressive increase in sound and power, without any annoying rasp or drone. The stainless steel construction is durable and built to last. The only downside is the installation process was a bit challenging, but overall a great purchase for anyone looking to improve their car's performance..
