Here at cp-e™ we know that you don't want to go faster, but instead you need to go faster. That need is why countless hours in R&D have been spent to develop the last turbo kit that you will ever need to look at for your Mazdaspeed3.


Introducing Atmosphere, the new Mazdaspeed3 Turbo Kit by cp-e™. The ultimate big turbo upgrade for your Mazdaspeed3 application includes everything you need to take care of your need for speed and to take your car from a stock turbo to a new Tial Stainless Steel Big Turbo.


This kit comes with an exhaust manifold specifically designed with Tial flanges to fit Tial VBand Turbine Housings from GT28-GT35, and Tial MVR External Wastegates. The =LRTmani™ Turbo Manifold is a stainless steel exhaust manifold that comes in a cast 304 stainless steel, and is designed to allow for the most efficient exhaust flow possible.


A common setup for the turbo bypass is to use a screamer pipe, which dumps the exhaust to the atmosphere immediately after the exhaust manifold. This practice is lackadaisical at best, so cp-e™ has taken the extra time and effort to divert the exhaust correctly. The cp-e™ DownScream diverts gases straight into the exhaust pipes to be expelled out of the rear of the car. Having this setup keeps your high boost events quietly intense, rather than noisy and agonizing. cp-e™ has designed this downpipe to keep your system within a legitimate decibel range.


The shining piece to this kit is by far the cp-e™ Mazdaspeed3 DownScream. Made with 3" 304 stainless steel, this downpipe eliminates both stock catalytic converters to allow for smooth exhaust flow and transition. Not only is this downpipe designed to give a free flowing exhaust from your turbo, but it is also designed to attach to the Tial MVR External Wastegate. The wastegate actuates at high pressure and causes the system to divert the engine exhaust away from the turbo.


Also included is the cp-e™ XcelXL™ Intake and Nviscid™ Turbo Inlet Pipe that will give your engine the air it needs when it demands it so that your MazdaSPEED3 can reach higher horsepower ranges. No turbo kit would be complete without the proper coolant and oil lines. cp-e™ has done it right once again by also supplying you with steel braided —AN lines for your coolant and oil routing that will fit right in with your new setup. We're even giving you a CNC lathed —AN adapter for the oil feeder hose to allow you to attach to your Mazdaspeed3 with no worries.
