My HE are shot and so looking at various options. I am considering other weight saving, suspension & engine mods at the same time so might as well try and get a bit more out of the exhaust system. Car will be primarily set up for fast road with the odd track day thrown in so would not want to sacrifice torque for hp and need to keep the sound down to reasonable levels and flatsix not V8 sound. I do have a good used set of 993 HE so one option would be to head that way but am open to other options.
