*AR Design Catted/Catless Downpipes 135i/335i/xi/535i/xi/1M

ModBargains is proud to introduce the new AR Design Catless and Catted Downpipes for the 135i/335i/535i. The AR Design Downpipes are the only true 3" downpipes currently on the market. The AR Downpipes will give your N54 an exotic and aggressive exhaust note as well as a significant boost in horsepower. These downpipes also virtually eliminate turbo lag, and will make your car's engine even more responsive. Give your N54 engine a boost in performance while upgrading to a downpipe that features some of the highest quality construction in the industry.

AR Design has been in the downpipe industry since 2006, and have never had a return on a downpipe due to a quality or manufacturing issue. Additionally if you do choose to sell your AR Downpipe at a later date it is proven that these downpipes hold their value much better than that of any other of the cheap downpipes.

• The only true 3" downpipes on the market
• 100% hand crafted in the USA from 304 stainless steel
• Water-jet cut flanges & CNC'd V-band flanges
• 100% TIG welded and argon purged - Compared to competitor's which are not
• Includes bomb proof gaskets and hardware
• Uses factory locations 02 bungs
• Available 2000° F ceramic coating. Coatings come with a 3 year corrosion warranty
• Lifetime warranty to original purchaser
• AR Design does NOT grind/polish their welds. Polishing/grinding welds compromises the strength of the weld and can lead to weld failure especially in high heat applications
• AR Design Catted Downpipes utilize MagnaFlow 3" metal substrate race catalytic converters
• 0% failure rate - No AR Design Downpipe has ever had a manufacturing defect
• Great customer support, unlike some competitor downpipes which will have no support in 1-2 years
• NO check engine lights on the catted downpipes

Ceramic Coatings
The AR Design Ceramic Coatings are able to withstand temperatures up to 2000° F. In addition the coating offers excellent chemical and corrosion resistance and has excellent thermal barrier characteristics, providing a dramatic reduction in radiated heat. This means reduced under-hood temperatures, accelerated exhaust gas velocity and a longer life expectancy for the downpipes.

Unlike previous ceramic coatings, AR Design's is not subject to cracking and flaking, which can lead to extensive engine damage. In fact, Ceramic coatings actually strengthen the coated part. The cured "Cermet" provides a cap of material that can withstand far more heat.

The Satin Ceramic Exhaust Coatings offered are the most advanced exhaust system coatings available. They are a very durable ceramic-reinforced coating available in various shades. When properly applied, it becomes the most effective thermal barrier coating available, increasing performance while extending component life, and has been tested to over 2000° F without lifting, cracking or flaking

2000° F coatings are available in the following colors:

Satin Black	Satin Blue
Satin Fresh Blast	Satin Grey
Satin Grey Ice	Satin Titanium

Below is a vehicle inspection report. This report shows the AR Design Catted Downpipes will still allow your 135i/335i to pass emissions.

Get rid of that annoying check engine light associated with running a catless downpipe.

• No more CEL (Check Engine Light) in the Dash
• No more LIMP MODE problems
• Allows you to run a completely catless exhaust system or just catless downpipes without any problems

When you eliminate your cat from your car, your ECU in your car reads as running too rich and gives you a check engine light in your dash. This most commonly occurs when running downpipes or testpipes. Replacing cats with downpipes increases the exhaust flow of the engine and it removes all restrictions from your exhaust system, making your car breath better.
