                                                    MazdaSPEED3 3" SS Downpipe System Custom Performance Engineering is very pleased to announce the release of our new 3" downpipe for the MazdaSPEED3!

Following the same successful recipe we used for our MS6 downpipe, our new MS3 downpipe replaces the choked factory pipe and its two restrictive cats, with one high-flow cat and a 3" mandrel bend pipe.  The catalytic converter features a high-flow, all metallic honeycomb design, making it one of the most durable converters on the market.  The result of our efforts is reduced backpressure, decreased turbo spool time, increased horsepower and a more aggressive sound.  For an even greater dose of the same great sound and power, option out the downpipe without a catalytic converter,     OFF-ROAD USE ONLY.  cp-e™ Smart O2 Sims will be released shortly to eliminate the unwanted check engine light.

Although more power and great sound are high priority items when buying a 3" downpipe, the fine details are what ensure that the product will satisfy the end-user for a lifetime.  cp-e™ does not use mild "junk" steel or even cut and welded intermediate bends on this pipe.  Our downpipe is crafted from premium "bright annealed" 304 stainless steel and is mandrel bent throughout for less turbulent exhaust flow.  The flanges are 3/8" thick laser cut 304 stainless steel and critical portions of the pipe for high strength and durability.  Critical portions of the pipe are TIG welded.  TIG welds are usually avoided in this industry because they require more time and skill than a MIG weld, despite the fact that TIG welds are better suited for thin metals, are better looking, and create a more durable bond.  We held nothing back with this product.

When paired with our new cp-e™ cat back exhaust system, the full cp-e™ turbo back system on MS3 gained about 30 horsepower and 40 lb/ft of torque to the wheels compared to the stock system.  There is more to the graphs than just the "peak gains".  The mid-range is greatly enhanced, and notice how much quicker the power comes on with the cp-e™ turbo back installed.

What is arguably the most attractive feature of this exhaust system however, is the sound.
