i'm going to do handmade a 2-1/2" stainless steel sport exhaust, under rear axle, with tru-x perforated core center muffler and 2 rear straight through perforated core by Magnaflow.

3-1/2" quad rear tips by Remus ( you can see OEM vs Remus )

2 sport cats 100 cells with the addition of 2 emulators to avoid errors to the control unit of the car.

sound + performance!

 

What brand of center muffler are you using? Keep us updated, want to see those tips!

 

mufflers made by Magnaflow

 

I like that x-pipe muffler. Do you have a part number for it? I can't locate it on the Magnaflow site

 

Hope you have an XK8, I did the same thing to my XKR and the drone was awful.

 

Please post pictures under the diff when done, and a measurement of the
ground clearance there.

all exhaust will be assembled at the end of September. We are also thinking of producing a small complete set of catalysts 100 cells (or even 75 cells) complete also of simulators for the ECU. I will let you know when we're done (and video where we will hear the noise).

 

100 cell sport catalysts... arrived

 

You know that the catalyst efficiency monitor function of the downstream O2 sensors can be disabled in the ECU and you do not need those things to trick it.

With the AJ33S you actually lose some power by falsifying the downstream O2 measurement.

Nice work, looks great. How's the sound. Can you say $$ Ka- Ching $$

 

cant see your exhaust for some reason

 

Cambo,
are three days that I tests my car with the new exhaust system and new catalysts to 100 cells (without simulators) . For now, no error signal! maybe because I blindfolded catalysts allowing them to warm up before?

AWESOME performance and sound !!!!!!!!!!

NEW SETUP for NEW 4.8L ENGINE.

soon the exhaust manifolds will be ready with the ceramic coating.

 

ceramic coated manifolds....

 

How do you disable the downstream O2 sensors?
I put similar cats on a few years ago and when I take her on a long road trip I get the check engine light with the Downsteam O2 sensor right bank as the fault. It only happens when I've been driving the car on the highway for a couple of hours, but none-the-less, I'd prefer not to see the check engine light.

 

you can disable with remapping ECU.

but i can also delete the error from my Garmin EcoRoute HD

 

unfortunately as soon as I open the butterfly valve, the traction controls enter and cuts off the power
