M3/M4 MP exhaust question

[squirdan]

hoping to tap into the M knowledge here

am v tempted by an M3 which has the full BMW M Performance exhaust fitted (complete with invoice for £3800 fitted)

call me mad but I think its too noisy

can I swap it for standard? my confusion is i've read that the old exhaust is cut off and the new one is clamped on, as the M performance exhaust is not just the back box but the longer pipes up to (or beyond?) the pre cats

so its not clear to me if I source a standard exhaust will it fit?

i'd be happy to swap the whole thing with someone with a standard car, plus cash, if anyone is looking for a cheap way into one of these?

it has the titanium ends and has done 5k miles

cheers
