Default Custom exhaust and mapping

Just been to powerflow near me to chat about a custom exhuast and map, I want the V sound, I want it to growl when you boot it and bark when you rev it but i do not want the drone at 70, 80, 140... whatever cruising speed.
Very pleased to find out the guy has an 08 w12 himself so feel in good hands! He says possible 75bhp gains but will have to see, i didnt think you could get that much from an NA engine.
Be cool though!!

I would be very surprised if you got gains like that.

Be nice if you got a before and after dyno run from them to prove it.

If he does indeed get that out I would pay for an increase like that.

75bhp seems very optimistic from an n/a engine.

I'd still vote to remove the centre silencers and tie the butterfly flaps open! I'll upload a vid soon

You won't hear much drone at all because of the sound proofing and twin-pane glass etc.

you'll be lucky to get 15bhp from an exhaust change on a n/a engine. more important is the sound, however

You just spoiled the whole fun guys for Rick
I guess if a another map uploaded with full exhaust made up, filters 75 may be possible. AMD in essex provide similar service, similar gains mentioned
Guys lets remember lambo runs 500 standard from stable
Lets be optimistic

Haha no hadn't spoilt my fun.
I was going to go with a quantum map, says around 25bhp increase which i thought was good given that its a NA engine.
Its a plug and play jobby, no rolling road setup.
I have one on my 2.2ST tdci work car and its a very good company, improved everything!

Now this other chap at powerflow i think its a live road setup but not 100% on that yet.
At the mo we are just going with afrint and centre section with one pair of cats removed. More V sound.
If i then decide its still not enough he will do another section.
I want to keep the standard look of the end pipes. Not interested in making it obvious looks wise.

Yes I agree with you all and I would be completely suprised by a 75bhp increase with just a custom map. But he has obviously played with his w12 which i believe is about the same bhp as standard around the 450 mark. I would be over the moon but so long as the engine is not working to capacity. I still want it reliable!
Anyway its all booked for the 25th of this month so will see what we see!

From the standard headers as i kept the precats, also its an engine out job to upgrade the headers! right back to the standard boxes is all changed. So still options to change the boxes for a deeper/louder sound if i want.
