I've got an SPT Exhaust that I'm planning on installing anytime soon. I've got a 3" gasket and a gasket maker just in case. But anyway, I'm looking to see what your guys' next suggestion would be to put on the car in terms of aiding the exhaust. I've got a 2014 WRX Hatch with the only mods being: whole stereo system upgrade and a new SPT Exhaust upgrade coming. Just quick suggestions, if possible and I'm trying to stay on the safe side of things in terms of car longevity so I don't want something that will damage the engine little by little.
