Anyone here have a direct comparison to how much the main downpipes add for power? I currently have secondary downpipes and full Remus so trying to see if it’s worth taking out the front set

High Elevation

You guys with your low to negative DAs make me so jealous. Check these out.

I should head to the Gulf coast while it's still winter.

Downpipes and Stage 2 e30 OTS tune. Forged wheels.

Yea, I was surprised to get that low. I've only had the car for about 3 months now. I'm impressed at just how fast they are. In my little rural town, there isn't anything faster.

M5 F90 SWR St2 E40

hi guys, here are my results, in custom tune By (JDL__87 SWR Team) instagram. Only downpipes, XHP, E40 fuel. The car is made for rolling launch runs, 1000 meters. 200-250 kmh seems to be a good result. For the 100-200 we made a good torque limit to preserve the connecting rods.

Did some 60-130 runs this morning (first negative DAs of the season), was pretty good for mods I think. Will post dragy later today

One invalid run that I cannot figure out, same road same direction on all the runs above lol

Mods are pump 93 octane, Dinan inlet with bmc drop in filter, Racechip on 7, catless secondary with resonator delete.
(muffler shop did such a bad job I believe I added the restriction back to the exhaust with the resonator delete. Apparently they used a 2.5 to 2.75" pipe)

M8 coupe with factory Pirellis that are atrocious for drag racing. Ordered new tires today, tire mod alone will probably make car faster than any additional power can. Tires only have 4k miles on it and look brand new but suck on launch.

Solid times!

Is that launch control or manual? Still trying to find the best settings

Suspension - I've always been in sport+ but heard maybe Comfort is better?

Traction - I've been doing 4wd Sport based on recommendation but didn't notice any real difference vs 4wd in my dragy times.

Any other tips?
