Looking good. I did the SW Redline Series before I put the car down, along with secondary cat delete. Sounded amazing. I did long tube headers and primary cat delete soon after. Sounds even more amazing, but the volume with the valves open is a little much. I do wish I went with the Legend series, particularly once this thing starts chopping, volume will be a nice issue to have, but still an issue. With the valves closed it was still pretty tame even with LT's and catless. I really like the deep tone from the Stainless Works mufflers though.
