hi,
has anyone got experience of having a 2.5" exhaust fitted to a bravo hgt? its a pre vis 20v and at the moment ive got a 2.5" downpipe coming from vis manifold (late collector type) that ive reflanged to 2.5". the system is then 2.25" from the downpipe all the way back with no cat. the car is quick as it is but im wondering how much mid range ill lose for the gain at top end. at the moment it pulls well from 4k and im wondering how far up the power band will move. itll be getting chipped soon so ive no doubt ill see top end benefits. what do you think?
John
