the raspy noise is what i had on my other set up, have you got remus centre pipe on (or a racepipe), thats makes a raspy sound.
Sounds subtle, but looking on those vid's there seem to be blue in the smoke, (if my eyes arent playing tricks on me) you might want it checked out. Burning oil is rarely good.
Been following your car diary mate so all ready seen them.
love the sound of it sounds very simlar to mine.
The early bird might get the worm, but the second mouse gets the cheese.
Think your eyes are playing tricks on ya mate
i check my oil regulary (can't spell ) and head gaskets been done nearly a year ago now, also i've been checking the coolant alot since then lol
buuuuut just incase i'll keep an eye out when i start the car now cheers for telling me
sounds nice m8, what year is it? I have a manicat so cant go for the sports cat option without having a lot of cutting and splicing done or a whole new manifold made up.
