I'm looking for some stiffer exhaust hangers that are the stock length to put on my 2013 wrx. I suppose I'm looking for something like this: https://www.rallysportdirect.com/fi...kb-011-12mm-kartboy-12mm-black-exhaust-hanger I have an unused bung on my exhaust and it is currently rubbing/vibrating against the transmission/mount, causing a significant amount of noise. stiffening up the exhaust hangers should help keep it from getting to that point at all. Thanks
