Having changed the exhaust manifold on the rallye i will need to get the map changed again. Before i do this i want to know if anyone is aware of whether a 2.25" exhaust on n/a engine becomes restrictive once your are at around 230bhp? If so i will have to change to a 2.5" system but dont really want to do this if the 2.25" system isnt going to be restrictive?________________________________________ 2.1 16v 306 Rallye. |

As long as you have a 2.5" downpipe and it's a decent system (straight through silencers,mandrel bends) I'd say it'll be fine.________________________________________ www.bridgecraftmotorsport.co.uk |

Sandy built the engine so may have to get in contact with him, thought id ask here 1st though to see if anyone had an idea. ________________________________________ 2.1 16v 306 Rallye. |
