Navigator Performance Online

A common place question, and usually one of the first aftermarket add-ons done, second only to the air intake. Lots of people have been going away from the best performance names, like Flowmaster and Borla and using names that just a couple of years ago were trash, like Gibson and Magnaflow. I can't see paying over $500 just for a muffler and a few feet of pipe. $500 was a low end price w/o shipping for magnaflow, and Gibson was higher. I found a Flowmaster Cat-Back in Summits catalog for $390 shipped to me, but decided instead to build my own. I went with a true dual, unequalized 3 inch system. I have yet to add the headers, seeing as they for whatever reason are worth your first born child at $800 a set. I used Flowmaster 40 series (really loud, 70 series I believe is the quiet SUV muffler, and if you want quiet get Delta-Flow technology enhanced versions) I have a pic for you to see, but it was hard to get a truely good picture of the exhaust from home without a lift

Yeah, there are a couple leaks on the end and one at the muffler. Things to be done, not really on top of the list

I recently changed to Flowmaster 50 series mufflers to quiet her down a little bit, but I really didn't notice a difference. Its still loud as hell
