Audi A4 Quattro Replacement Exhaust System Information


Your Audi A4 Quattro exhaust system starts at the exhaust valves. When the exhaust valves open, they expel burned fuel into the exhaust manifold. The gases then travel through the exhaust headers, through the exhaust pipe, through the catalytic converter where it burns up any leftover fuel. The spent gases are pushed out of the catalytic converter into the tail pipe and then released out into the air. The exhaust system does not require a great deal of maintenance other than ensuring that the catalytic converter does not fail which would be immediately evident by an odor similar to rotten eggs. Since water does also escape through the exhaust system, the pipes can rust from the inside out. Depending upon your climate, salt on the roads can also damage the system. If the exhaust pipes rust, they can allow exhaust fumes to enter into the cabin of your vehicle, a dangerous situation that may cause great bodily injury. The exhaust system in an Audi A4 Quattro is rubber-mounted which removes exhaust system strain, making failure less likely. It is a good idea to check these rubber mounts regularly to ensure they are not damaged by heat or weather conditions. Be sure to purchase high-quality parts when repairing your exhaust system.

    Reviewer: Talk about a great value...

    Purge valve to be exact. I got this part for $22. Everywhere else the price was $75 up to $400! I installed it in 10 mins and works perfect. Great product at a great price. I highly recommend this company.

    2005 Audi A4 Quattro Exhaust System

    Very Satisfied
    Reviewer: Borla makes a good product

    I purchased this exhaust to replace an OEM unit that had rusted through. The OEM replacement cost was extraordinary. The Borla product is well manufactured and fully stainless so no more worries about rust. Install was very easy with two people. Note that is does require reuse of the existing sleeve and clamps at the downpipe. My clamps were rusted through, so I picked up two Accuseal 2-1/4" band clamps, which worked great. The exhaust came with Accuseals for its joints. The new exhaust note is throaty and deeper than stock, but not louder. Some might not want that, but it was perfect to keep the car close to stock (as I intended). No drone at all at speed, a little more turbo noise and growl when at high rpms, but in a good way. Overall very pleased.

    2007 Audi A4 Quattro Exhaust System

    Very Satisfied
    Reviewer: Muffler

    It arrived very early. It was in great condition but was a little disappointed in the packaging it was shipped in. But I guess it isn't the easiest thing to box up. The ends had small butd of cardboard and paper taped around them. Oherwise, perfect fit with no complaints about the actual product.
