Is it a .48, .55 or .63?
It doesn't have the markings on I would expect to see, it is a t34 off my m8's cossie I want to change the exhaust housing on my race car to a .63 and was going to use this but it looks no bigger than my spare .48 that I have placed alongside it to compare





cheers,

Sometimes the size is just inside the housing where it bolts to the exhaust manifold

looks like a .55 housing to me.
has it got a number 5 stamped just inside the manifold flange?

Its a .55 housing. I have got the same one on mine. 'CH' stands for Cheat because this is what they were used for in Motorsport so you could not identify them on the outside. Look for a '5' stamp inside.

Great housing, almost same spool-up time as a standard .48 housing but gives more power up the revs.
