Full set of left and right headers and cats is supplied where applicable or on turbo models a full downpipe often with the mid pipe is included in cat or decat.
This RS3 Downpipe is DECATTED (recommended) and includes a heat shield as well as the mid pipes! These are the best sounding and looking downpipes on the market and are available at an amazing price. 100% brand new, 100% T-304 Stainless Steel with computerized mandrel-bends CNC-machined flanges for strong solid support TIG-welded for strength and durability 3-stage polish for a mirror-like finish on some exhausts We offer 3 different options when purchasing. Where applicable Heat Shield installed lowers engine bay temps by upto 60* Where applicable 100cell or 200Cell High Flow Catalytic Converter Installed for performance whilst maintaining emissions standards Where applicable decat (without catalytic converter) for max performance and better suited for crackle/pop on deceleration. We offer install and dyno tuning on this item in Victoria!!! For overseas customers we have outlets in many countries, feel free to ask us for tuning/install if required!!
Q: For which vehicles is it necessary to buy a pair of headers? On your website are headers automatically sold in pairs for these vehicles?
A: When purchasing exhaust headers for a V-6 or V-8 engine, the header package is complete with two headers. If your vehicle is a 4-cylinder, there only a single header that is uséd.
Q: What does a header do? Why buy a header?
A: An exhaust header is a performance product that replaces your factory exhaust manifold and improves an engine's performance by allowing air to flow more freely. The easier an engine breathes the more power it produces. Headers generally use piping with a wider diameter than factory tubing, which allows more air to pass through the exhaust system than factory. A header is one of the easiest bolt-on modifications you can make to increase horsepower, making an effective use of money if your goal is to quickly gain horsepower.
Q: How do you install a header?
A: A header is a direct bolt-on. Simply remove the factory OEM exhaust manifold and the aftermarket header is put in its place. The header is to be attached the head of your vehicle. Remove all the bolts that hold the flanges in place and detach the factory manifold. The down pipe or exhaust pipe should be removed as well and then reattached once the header flanges are bolted back onto the head.
Q: How much does the material uséd to make the header matter?
A: There are two main materials that headers are manufactured out of: ceramic and stainless steel. Ceramic headers are less expensive, but are prone to cracking if they get to be extremely hot. Stainless steel headers are more expensive but are more durable and generally more stylish. Stainless steel headers can take any kind of heat you throw at it and not prone to cracking.
Q: What are the different tubing options for headers and what is the difference between them?
A: There are two major designs for headers: the 4-2-1 design and the 4-1 design. In many cases 4-1 headers are designed for racing applications where the vehicle is being driven at or near redline. The 4-1 design maximizes top end power, whereas the 4-2-1 evenly distributes it throughout the power band. Either way, you're going to be getting more horsepower from a header.
A. For most euro vehicles we offer catalytic and non catalytic converter options as well as heat shield options. Downpipes and headers with heat shields will help lower intake engine bay temps by upto 60*, some vehicles are incredibly prone to heat soak! More so during stationary or low speed use. On our website you will have the option if applicable to purchase them with cats, decat or with heat shield. On other platforms you will need to look at the picture to ascetain whether it has it or not.
A. We recommend tuning any vehicle built after 1996 with a header or downpipe install. More so if you've gone the decat option (where applicable)
A. If you want max noise decat is best, you will likely get engine cat codes like P0430 and P0420, which can be cleared in a tune. Decat will not pass emissions testing, 100-200cell cat options are more likely to pass emisssions but we cannot gaurantee this due to the age and condition of your engine being out of our control.
A. There are strictly no returns on these items once used. We do not cover return shipping for swap over parts.
