Hey guys I was hoping someone here maybe able to shed some light on the issue im having with my exhaust system.
Ok I have a Mazda RX8 and last october time I had my engine rebuilt by a rotary specialist and since then ive had this rattle and buzzing noise from my exhaust I have a full stainless system header mid pipe and catback now ive tried everything ive swapped out the ss header I had fitted during rebuild (was a cheapo) with a decent one ive swapped between my high flow cat and a decat ive also stuck my old oem catback on but its still there ive replaced my engine mounts encase there was excessive movement there ive been underneath and checked up and down the pipe but can see now contact spots all the heat shield are solid.
Im at a loss people have said its just the side effect of a full ss system but a mate has a virtually identical setup and no rattle others say its the engine and a side effect of the porting I had done during rebuild but again mate identical setup etc so what for the luv of jeebus is it.
Here,s a bad video of the noise
