FS: GT4 X-Pipe for Akrapovic

Item Interest
Hello.

I have for sale a GT4 x-pipe center section from my race car. It is a custom piece I had made of 18g 304 stainless steel from Burns Stainless and is designed to replace the x-pipe from a FULL E90/E92 M3 Akrapovic exhaust system.

It was on the car for a couple seasons prior to the car swapping over to custom headers and a custom dual 3" stainless steel exhaust system.

Please see pics of the piece below. It is a work of art.

It saves 5 lbs over the Akrapovic x-pipe. It adds horsepower and adds an incredible sound to the car.

Please note: This is the only piece included and is of value only to those that already have a FULL E90/E92 M3 Akrapovic exhaust system. It is a stright swap-out piece.

$1500 OBO price does not include shipping.

Please let me know if you have any questions or want a shipping quote.

Thank You,
-Ralph Warren (Irvine, CA)

To confirm... this piece adds a great sound to your car but it is not too loud for a street car... a nice balance.

Just to clarify, you cut up an EVO X-pipe and installed this stainless steel piece to the titanium X-pipe?

No. The Akrapovic x-pipe is still untouched. This piece replaces the Akrapovic X. It is the same length, same input / output, etc.

Hard to say how much louder. With the mufflers still in place I would say it is not TOO loud. The mufflers do most of the work for sure.

This GT4 X-pipe center section from my race car is still available.

It is a custom piece I had made of 18g 304 stainless steel from Burns Stainless and is designed to replace the x-pipe from a FULL E90/E92 M3 Akrapovic exhaust system.

It is a direct replacement for the Akrapovic center section for those with Akrapovic E90/E92 M3 full exhaust system.

Please see pics of the piece below.

It saves 5 lbs over the Akrapovic x-pipe. It adds horsepower and adds an incredible sound to the car.

Please note: This is the only piece included and is of value only to those that already have a FULL E90/E92 M3 Akrapovic exhaust system. It is a stright swap-out piece.

$1500 OBO price does not include shipping.

Please let me know if you have any questions or want a shipping quote.

Thank You,

For E90 M3 or E92 M3 owners with an Akrapovic cat-back system... this is an awesome piece for you. Direct bolt up in minutes.

Hi. Yes... it is still available.

Let me know if you want to see it in person or if you want/need additional pics or info.

If you already have an Akrapovic for an E90/E92, it is a great addition. More power, better sound, less weight.

Iím no expert on metals so was wondering if you knew what is the main difference between 18g 304 steel vs titanium. Just wondering how much the difference is between this and an actual Gt-4 x pipe and your decision to have one fabricated vs buying a gt4 system itself. Thanks

This part is still available. If you are looking for more power, less weight and a little louder Akrapovic exhaust... this is the part to get.

The GT4 part is a fortune and this part produces more power on the dyno.

Just to confirm... my part is made of stainless steel and REPLACES just the center section "X" from a full Akrapovic E90/E92 M3 system. My piece is off my race car and is lighter, louder and produces more horsepower.
