Im thinking of buying a 2013-2014 E63 and curious what kind of power most car on this forum is making. I've seen stock range from 470hp to as high as 540hp at the wheel. For those that have dyno their car. Please post your number whether stock or modify. Both would be even better so all of us can see the increase before and after. Please list your mods and tune.

numbers doesn't mean much , 13 and 14 big different , S model even bigger different .

PP performance tune
down pipes
BMC filters

PeterUbers

Is that at the crank or at the wheels
Those numbers are post tune if those are at the wheels

Georgee6086

To the wheels, with the tune.
Everything thing else is stock, air filters exhaust.

Forgot to mention that was with 91 octaine gas

703 PS to the crank? if so then about 590 whp

mjd222

no 606 whp

Not to get off topic, but any idea of what the gains are for adding the down pipes? My car is at the exhaust shop as we speak getting the cats removed.

know i will use brask plugs and see if any change in power .022 gap
for tuned M157 use the same plugs as the mitsubishi lancer evolution x

i took reentech spec down pipe and made it at fox for 600$ lol
down pipe w/o catts
whit out tune will will gain 5-10 HP
but you will get the turbo sound wow

Georgee6086

Ughhhh that's what I'm hoping to acheve, that sweet turbo sound.

mjd222

man it sounds so goooooood

efiftyfizzle

What do you mean? How did you get the spec of their downpipe?

mjd222

one of my friends has the renntech down pipe
i removed it and took the magarmants for it and give it to fox exhoust and the made one for me
2000SR saudi riyel (533$) whit fitment loool

This is the issue, the prices they are charging for just down pipes is silly...
If it were a complex header design then maybe i can understand, but for simple semi straight pipes costing 3-5k is just

Georgee6086

My exhaust shop said all they needed was the turbo to down pipe gasket and they would use that as a template to get the flange made and the rest of the pipe is no problem at all to make. I decided to just cut out the cats if fear of wearing them out as my car already has high mileage. Picking it up in a few hours, can't wait to hear it.

this is why its not really worth it (at retail prices) unless people get the style that eliminate the bridge pipe too (pipe that comes directly off the turbo)... the type of downpipes that ams and renntech sell mate up to the bridge pipe, not the turbo, so there's not really any gains as the main restriction is in the bridge pipe.

of the 3 main US tuners we see on the forum, only weistec replaces the bridge pipe with less restrictive one... there are a few other companies that have weistec clones like cks and boost logic

true downpipes should pickup about 40whp... (the weistec dyno's have shown this)

mjd222

Ya I know that's why I made one for 533 $
It is only pipes that's all why 2K+!!!!

Weistec whit tune you get 40HP

gaspam

yeah i agree at the price you got its worth it, but at $3000 like renntech and ams, not really worth it.. now if the ams/renntech pipes did replace the restrictive bridge pipe then i would have no problem paying $3K for them

efiftyfizzle

Post your before and after dyno... Also, which E63 do you have? I'm hearing the 2012 downpipes won't fit on a 2014.

mjd222
