what power would i make?

[Brecht]

As the title states, curious what power i would lose.
I'm thinking about getting it remapped with the oem exhaust manifold!

Currently makes 247bhp and 238Nm , pw jdm intake , tegiwa v2 exhaust manifold , rrc ( not ported with oem tb), and mugen twinloop.
vtec at 4000rpm
Did change to an rm01a a year ago but didn't dyno it.

i'm guessing torque would improve in the lower rpm range,i'd have to raise the vtec point as it would choke at 4000rpm ( it's the case now if i change to oem manifold on ther current map for MOT )

any guesses?

Thanks!

love the power it makes now , just thought about the option if i wanted to quiet it down a bit.
i'll leave it as it is then.
thanks for the replies !

i had the tegiwa coupled with the twinloop for 4 years i think and the rm01a for 2 years (1 year on the side as the car was getting repaired from an accident )
rm01a didn't really make it louder , more tame on the lower revs , i think my twinloop was kind of broken as it sure was getting loud at the end haha.
i don't mind the sounds at all , really like it.
Just a thought that if i was getting tired of it, that i had an option of toning it down but still have the performance .
Oem manifold sure does quiet things down haha.
driving an mk8 fiesta st at the moment , just nice to have a "silent" car at times when you are just cruising along
getting rid of it as soon as the dc5 gets registered again.
Just repainting some stuff and checking things now it's off the road, repainting rocker cover , brembo calipers , doing valve clearences ( never done them since owning the car .. 55k km to 134k km yikes.. )
