JUST got back from putting that exhaust on. fug its quiet now. has absolutely no note, which is cool, because its got no whistle now either. so i'm no longer cop bait!! :P
and its sooo much happier sitting at constent rpm now, like cruising the highway.
still getting pretty hot though (espeacially on 10spi :| ) so i think i might do a water pump swap tonight. :D
I'll get back to you about the discs, if you sell them in the mean time thats cool, i've just been neglecting my mazda a bit lately so i better spend some money on that for a change!
