it probably was direct that had a 3 inch on the wall considering that they do mostly dsm work and 90% of dsms go with 3 inch applications, finding a 3 inch application for an ls integra is the hard part. as far as millinuim goes, they want like 750 to custom build a 3 inch exhuast. that just seems a little much to pay for an exhaust that such a small shop thinks will work or looks good so thats how they make it. i mean you can buy a full pre made, pre tested 3 inch set-up application thats tested over, and over to make power, look good, and sound good for less than that price.
