Hi Is it safe to say that there are no cats on 89 Euro 328's to begin with ? ( this may be a daft sounding question to many of you but in South - Africa there are no cat laws and only really late models have cats and have to run on unleaded fuel - as standard. I most definately run my car and always have run it since 1995 on leaded fuel as we only got unleaded fuel here in 1997 odd. I wouldnt know what a cat looked like if you hit me with it. Now that i think of it i have never seen a slowdown light in my car either. Also my car was origionally made for South - African market being RHD as well as i have found a factory sticker inside the LH door panel designating the car as being destined for South - Africa ( not UK ). It landed in SA in 1989, 8 - 10 years before unleaded fuel arrived here. All this board talk of Tubi's etc has got me going and now i too want nice noise. My car is just too darned civilised sounding. There is none of the Ferrari magic wailing and howling that im reading about here. I suppose i would go for a Tubi if i can find one here. I would not be tampering with the manifold or branches. Just the exhaust. I assume it will sound good ? Ive read about test pipes. They seem to mean straight through pipes. Does this mean that the cats are omitted or that the exhaust silencer is omitted... both or neither ? I have done my obligatory searches but still have these two questions. Many thanks Skin.
