ECS Tuning

Change the tone of your Audi B9 SQ5 3.0T exhaust with an easy-to-install upgrade from ECS Tuning! The ECS Tuning Center X-Pipe installs in place of the resonator located in the middle of the factory exhaust system to increase exhaust note and allow for better flow of exhaust gases.

The engineers at ECS Tuning have designed a direct fit dual exhaust pipe featuring an X cross section in the center to balance exhaust pulses and increase expulsion of spent exhaust gases from the engine. But more importantly, installation of the Center X-Pipe increases the factory exhaust system note exponentially giving a more tuned European sound. The ECS X-pipe is fully CNC mandrel bent from high quality 304 stainless steel, TIG welded with smooth merged pipe joints for optimal flow, and finished off with a soft brushed finish for exceptional looks. Installation is a breeze and can be easily performed with the vehicle lifted on proper jack stands in your own driveway. Our in-depth installation PDF, located under the Installation Tab, walks you through everything from proper measurement, cutting, and install to ensure a perfect fit to your OEM exhaust. We've even included a complete set of clamps to make sure everything is properly installed without worry of leaks.

Awesome GTI Delivery Information


For European Customers prices now displayed in cart once you enter your address will have 20% UK VAT Tax removed, however you will have to pay some form of Duties / VAT prior to delivery of your goods. If you are unsure of charges we recommend you should contact your local authorities ahead of placing your order.

Do we ship abroad ?

Yes we do, to almost anywhere in the world though remember the postage is often high when shipping anything bulky. Most bulky items we export will go by UPS so you can track the package online and could reach America within 48 hours providing its in stock !

However there are a few countries we do not ship to, some of these include: Thailand, Malaysia, Indonesia, Russia, Nigeria, Macedonia, Syria, Ukraine, Lebanon.

Why is postage on bulky items to some countries expensive compared to some other companies ?

For both yours and our safety we use well known couriers such as DPD Local and UPS for shipping, then we know exactly where it is in the world at any time and we know its going to arrive safely. Shipping small items can be cheap, but items such as bodykits are expensive to ship - we have a very small margin on the postage fees merely to cover packaging. We can now ship using standard post on some items, however using all methods you may incur import charges when you receive the goods for which we cant be responsible for.

  • ECS SQ5 B9 X-Pipe

    Posted by Bradley Lister on 18th Feb 2023

    I wasn’t wanting to spend £2k+ on a full exhaust system as I quote liked the tone of the stock exhaust, I just wanted it a bit louder. This X-Pipe, although it was on back order for nearly two months, was worth the wait. It’s simple to fit if you know your way around some tools and took me around 30 minutes start to finish. The sound, combined with the valve delete on the stock system is exactly what I wanted, deeper, throatier pitch which is still tame until you give it some throttle, the pops are more noticeable as well and it’s just overall a great product to add that missing excitement from the family car
