Ok, so I have done some searching here and couldn't find the answer I needed. I am looking at getting a Courtesy B-Pipe, but do not know what muffler to purchase for maximum flow. I already have a Stillen rear section, but I would have to get a flange to neck down from the b-pipe, right? I have saw alot of posts on the Apexi N1, is that the muffler of choice?

I am trying to see what my options are.

Keep the Stillen or get something else? And what would the something else be?

TIA,

Jerrod

really depends on how much $$$ you want to spend, what you want the car to sound like and how you want the tip to look. a handful of people, myself included, have the dynomax ultraflow. it's a straight through 2.25" design. sounds nice, drives nice, and is reasonably priced (~$50 shipped). you can buy your tip of choice and have it welded on. this set up including the tip but not the installation should be well under $100.

my advice is the same. Ditch the stillen and get an ultra-flo.
