@east_coast_s4554 2 года назад

So I'm surveying everyone with this DP for actual results. If you have obd11,Carista or even better VCDS. Can you scan and check readiness. Even though there is no CEL mine and many others do not pass 2 readiness checks - 1 for Catalyst and 1 for rear 02. Carbnlabs has claimed this is resolved in revision.

@GOOGLM3_NY 2 года назад

dg here. interested to see reply's.

@east_coast_s4554 2 года назад

@@Broprotato That's great, however I actually have your 2nd revision from this time last year with the update. I've never gotten a CEL from this, However it's the 02 readiness check that doesn't pass...to clarify these are 2 separate things, even though both might possibly be resolved with better welds... I know the run after mine had some issues with the spacer etc. I would love to just see a passed readiness check from this setup from someone out there 😅

@swift__ 2 года назад

Usually the DP is going to open everything up for a better/louder sound. Not much in the way of HP gain tho, maybe like 4hp? But I’m not sure if anyone’s ever dyno’d to get an actual number… ( but still sounds F’n great 😎 )

@jacobkruika8954 2 года назад

The downpipe is where you gain hp. Usually you can gain upwards of 15hp off a downpipe when going catless. It's the catback where you won't see much gain maybe 4hp like you said.

@UnrelatedNonsense Год назад

Downpipes give you very noticeable gains on turbo charged cars. The most restrictive part of your exhaust is the catalytic converter. Downpipes give you better turbo spool and flow

@swift__ Год назад

@@UnrelatedNonsense yea just gotta tune it after you put dp. ( I always swap mine out, except on our “family “suv. They’re still stock )

He has an aftermarket air suspension. So his oem shocks arent connected, which is causing the error light.

@mikemayers9353 2 года назад

@Broprotato 2 года назад

Once the catalytic unit is deleted, there is no real reason to keep a big bulky pipe with sharp angles. What matters here is the size of the Y collector which in this case is the biggest on the market and the straight line from the turbine Vband to the y collector. Only reason why the Vband flange diameter on the OEM turbine outlet is large is to accomodate for the big volume needed to package the catalytic unit. As an example, an EFR9174, good for 1000hp will have a turbine outlet of only 3 inches.

Please pay attention to what you're filming instead of just shaking the camera around the whole time, and please get a proper microphone. The production quality is horrible. I literally can't watch this because it's making me sick, and even when I fast forwarded I can't really hear much from the catless car. Thanks for the content, but please focus on the quality.
