Description

BMW E39 530D and 525D Dual Decat Turbo Downpipe & Twin Cat Bypass 2.5inch bore pipe increased into two 2inch bore pipes.

Fits all E39 525D & 530D Saloon and Touring models regardless of year.

This is a direct replacement for the standard primary dual catalytic convertor and down pipe that are fitted to the car from the factory. This downpipe will not interfere with any sensors or cause any ECU faults. If you are unsure or require assistance, please don't hesitate to contact us, we will be delighted to assist.

Built for performance, economy and longevity!

Performance - You will enjoy reduced turbo lag and a noticable performance difference throughout the entire rev range, the original downpipe exits the turbo with an immediate restriction as there are two compressed pipes fastened to this section. The extreme bends on the original downpipe are replaced with a straight 2.5" bore pipe which is extended allowing optimal flow from the turbo and a huge reduction in exhaust gas temperatures. As a result your turbo charger will run substantially cooler reducing your air intake temperatures, extending turbo life and the reduction in back pressure allows your turbo to spool up quicker with less effort.

Economy - You will experience a 2-4mpg improvement over the original restrictive catalytic convertor depending on your driving style due to the reduction in turbo and intake temperatures.

Longevity - Your upgraded dowpipe is over-engineered in 316 Marine Grade Stainless Steel and the flexible coupling in 304 Grade Stainless Steel, flanges are lazer cut for a perfect fit, your new downpipe should outlast the life of your vehicle. You should also expect your turbocharger to have a longer life as temperatures are greatly reduced.

How does it fit - This downpipe was carefully developed using the Genuine BMW factory item as a template and tested on the vehicle, improvements were made to flow where possible. Every downpipe is hand made using a jig ensuring a perfect fit every time.

Noise - There is no noticeable difference to the sound of the exhaust forby a near inaudible yet pleasing whistle which comes with the improved flow.

MOT - Removal of the primary catalytic convertors on the 530D has no effect on the MOT test. Your engine will produce lower particulate emissions due to a more complete combustion cycle. Petrol cars differ as they are subject to a full emissions test.

Quality - Our exhaust components are built with over 20 years experience in all kinds of fabrication and welding you can be assured that the quality of your new performance downpipe will be second to none!

Guarantee - A lifetime guarentee is offered on the pipework and as the uprated stainless steel coupling is a flexible part, we offer a two year warranty on the flexi section.
