Full BTB system inc 6 branch
Moderator: martauto
This is available now through the Zone and has given a proven 18 bhp on a standard 325i without any chages to the ignition or fuelling.
Around Ԛ£1100 +/- Ԛ£50. Still awaiting a price from BTB on the exhaust part.
The manifold gives a large chunk of the power and thats Ԛ£650.
