If you have a red top engine with tb's with about 200 bhp with an sbd exhaust manifold type A or type C, a racing cat and a good handmake middle-box to hold easy 200-220 bhp of the engine,
Can you put a Scorpion Dtm backbox (because i like it so much )?
Or it is only an aftermaket backbox to give improve only for engines with standard specifications?
I think that Scorpion do two types of their exhausts.
The normal type and the group A type.
Is it that corect?
