Talking N54 Downpipe Fix BUILD THREAD *** its finally available again ***

Hey guys,
Just wanted to share the good news with you that the N54 DP fix is now available
By purchasing and installing this product you agree it will not be used to facilitate the removal or defeat of any emissions control systems. Not legal for use on pollution controlled vehicles.




X-Kitty is a fully adjustable fix that eliminates timing pull, oxygen sensor miscalculations, check engine lights and tuning issues associated with high flow exhaust systems.
X-Kitty installs within the ECU wiring harness.
X-Kitty is compatible with all BMW performance tunes and N54 twin turbo engines.
X-Kitty does NOT work with the 2011 and newer N55 twin power turbo platform.
By purchasing and installing this product you agree it will not be used to facilitate the removal or defeat of any emissions control systems. Not legal for use on pollution controlled vehicles.




*Emissions Notice to Customers in California*
Wedge Performance sells only competition use only performance parts. Competition use only parts may only be used according to the guidelines posted below. California regulates automobile aftermarket parts that have the potential to impact emissions. In most cases, the sale and use of emissions related aftermarket parts on automobiles is prohibited unless it is either a "replacement part" as defined by California, or is a specifically authorized use of that part as reflected in an Executive Order ("EO Part.") The California Air Resources Board (ARB) regulates aftermarket parts and has promulgated regulations that essentially place all emissions related aftermarket parts into three categories: (1) Replacement Parts Replacement Parts are aftermarket parts that ARB considers to be functionally equivalent to the stock part they are intended to replace, and therefore would not impact the emissions from these vehicles. These parts are appropriate for sale and use on automobiles used on or off the public highways. For aftermarket exhaust systems and parts, there are two applicable scenarios: (a) If the automobiles stock exhaust system does not contain a catalytic converter, then an aftermarket exhaust part is a replacement part as long as the part does not remove or replace any emission control equipment originally attached to the stock exhaust system, such as oxygen sensors. (b) If the automobiles stock exhaust system contains a catalytic converter in the manifold section of the stock exhaust system, then an aftermarket muffler positioned downstream from the catalytic converter (i.e. cat-back) is a replacement part as long as the part does not remove or replace any emission control equipment originally attached to the stock exhaust system. (2) Executive Order Parts Executive Order Parts are aftermarket parts that ARB has evaluated and determined do not adversely impact emissions, and thereby are granted an Executive Order (EO), which allows the part to be sold and used on specified automobiles. Any aftermarket exhaust system that replaces or otherwise impacts emission control equipment, including catalytic converters, requires an EO to be sold and used on a automobile used on or off a public highway. (3) Competition Use Only Parts may not be sold or used on an automobile that is used on or off the public highways other than those automobiles used exclusively for competition. Competition Use Only Parts are aftermarket parts that replace or otherwise interfere with the operation of an emission control device, such as a catalytic converter or oxygen sensor, and may be sold and used on an automobile that is used only for closed course competition. THESE PARTS ARE LEGAL FOR USE ONLY IN COMPETITION RACING VEHICLES AS DEFINED UNDER CALIFORNIA LAW, AND ARE NOT LEGAL FOR USE IN ANY OTHER MOTOR VEHICLE. California law defines a "racing vehicle" as "a competition vehicle not used on public highways." (Calif. Health & Safety Code 39048) These parts may only be used on competition racing vehicles operated exclusively on a closed course in conjunction with a sanctioned racing event. Competition-only motor vehicles may not be driven to a racing event on a public highway and must be transported on a trailer or other carrier. USE OF THESE PARTS IN ANY OTHER VEHICLE MAY SUBJECT YOU TO FINES AND PENALTIES FOR VIOLATION OF FEDERAL AND/OR STATE LAW, WILL VOID YOUR WARRANTY FROM WEDGE PERFORMANCE, AND CAN VOID YOUR VEHICLE'S WARRANTY. It is your responsibility to comply with all applicable federal and state laws relating to use of these parts, and Wedge Performance hereby disclaims any liability resulting from the failure to use these parts in compliance with all applicable federal and state laws.

Im not sure if i can post the price.
I think if i do the thread will be considered a Commercial one instead of a build thread.
Sent a message to the admins to make sure i am not violating any rules. Still waiting for their reply.

When you NEED this thing to pass emissions, you pay what it costs.

That's high, but he's the only game in town unless you do the "build your own" way.

I think this is great news, and now I can go ahead and start pushing pennies toward some damn downpipes!

$140 ouch

=$10 for shipping ? ouch again. Bet these $10 covers parts necessary to build it + shipping cost...

That's one expensive O2 simulator...

Let's hope VRSF comes out with theirs soon. I bet theirs will be half the price of this.

I heard leaving the dp fix in is actually bad for the car? It starts to mess with your timing and afr's. This is why I thought it was recommended not to leave it in and using the auto clear function on tunes. And only use dp fix when needed for short term purpose.

You do not want to keep it all the time.

Wedge had an intro price on these for the first few samples.
That price has changed.

I thought you could change the setting to inactive. I have had no issues in that position.

Any proof, logs, etc.

As long as the wire pin outs for the N52 are the same for the o2 sensors, this will work as it just stabilizes and divides the voltage to keep within parameters.

I'm glad you asked.


There's a good demand for it and no other vendors are selling it. No competition. Simple economic, supply and demand. To be fair, if it's that easy and cheap to make the dp fix, why don't you start making it and sell it for $20? lol

if the there's not enough profit, these vendors wouldn't have an incentive to make and sell the fix.

I did this

https://www.google.com/search?btnG=1...tch&gws_rd=ssl

First search result.

Just wire in a bypass switch, then I can turn the DPFix on when I need it and off when I don't all from outside the ECU box.
