Updated: All Cats and resonator deleted and added h and x pipe ala Akrapovic added

Hey Guys,

So I dont have the video yet as I had to come straight to work, but I had a pipe made from the headers to the stock muffler. Basically it is exactly how the Akrapovic Pipe looks like (not exactly but kinda like the ugly sister). H-Pipe first and then x-pipe with no cats or resonator. Absolutely no drone. Actually if you arent accelerating you cant even tell there is anything different at any rpm.

The sound is exactly what I was looking for. The "volume" is almost the same as stock, but it is very high pitched (not sure that makes sense). I am going to get a video to show exactly what I mean.

Here is a crappy pic I took with the phone. You can atleast see where the "h-pipe" is located.

I am getting my cat delete pipes for my AA x-pipe Tuesday, so I will be running no cats, with resonators, and the stock exhaust. It should sound great.

I just bought a stock OEM mid pipe with just the secondary cats deleted. Looking for this result on a lower level.

Got it off another member here.

Yeah the muffler shop nearby has a mandrel bending machine so it is pretty close to what you could buy from a brand name (welds arent as nice though)...

I have thought of doing this!

What size of the pipe did you use?? Diameter The stock Diameter is 2.40 inches.

Why doesn't the Check Engine Light come on? is it broken?

So there's no drone while cruising on the freeway?

He has AA software for the O2 sensors.
