Got a 3.5" downpipe I don't need anymore. It was made by gnpartsonline.com I believe, they aren't around anymore. I had to do some work (oversize flange holes) to make it fit but it does fit pretty well now. A little scratched up from installation, but functionally in great shape, I tig welded on a o2 bung for a wideband. Looking for a quick sale at $275, if you include shipping it would be more than double for one of these now. I will also include a 3.5" band clamp for the dump pipe and DP is ss not totally sure of grade but I assume 300 series. PM or call 8087790076 Tyler
