Hi guys, Has anyone replaced their exhaust middle muffler with a resonator? If you did, what happened to the noise levels? I've got an R34 GTT sedan with an R33 HKS Super Drager (the one with the massive rear muffler) modified to suit, but the middle muffler is sitting really low and regularly scraping. I'd like to replace it with a resonator (to run under the transmission tunnel) but I like the relative quietness of the exhaust system as it is, so I don't really want to make it louder... Also, what catalyser would you recommend to flow 300rwkw? Needs to bolt on to 3" flanges. I'm thinking a 200cpi metal cat of some kind. I've got an X-Force ceramic high flow currently but it's suspected of restricting flow. Thanks!
