Description
 

StreetUnit SUS 304 Stainless Steel Test Pipe (Catless)
Application: MAZDASPEED 3
Part Number: SUMS3SSTP
(Off road use only)

The StreetUnit Catless Test Pipe replaces the second catalytic converter on your MAZDASPEED 3. It is constructed using 3.00" SUS 304 Stainless Steel Tubing and CNC machined flanges. The SU Test Pipe removes the severe air flow restriction that the stock catalytic convertor inhibits onto the MS3 exhaust system (photo below). Removing this restriction will greatly improve the performance and power for your MS3.

The SU Test Pipe is a direct bolt on replacement for the second catalytic converter. For flexibility, it reuses the stock donut flange system to allow for necessary movement. The SU Test Pipe includes all necessary mounting hardware and instructions to make this installation a breeze. The removal of the 2nd cat will NOT trigger any check engine lights. The test pipe will bolt right up to both the stock and aftermarket catback exhaust systems.

Test pipe is perfect for the MS3 owner that...

...Does not want the hassle of installing an aftermarket downpipe
...Does not like the prices of aftermarket downpipes
...Wants to avoid Check Engine Light issues with aftermarket downpipes
...Wants cost efficient HP gains
...Wants an easy, bolt-on install
...Wants sound kept to a minimum
...Wants the ability to easily swap it out for "dealership" visits

5 of 5 Great product + Fast Shipping = WINNING March 24, 2011
Reviewer: Chris from Tuscloosa, AL United States  
This test pipe is much lighter than the stock...great looking design.  Had no problems with installation (except for removing the stock mid pipe from the hangers)....Other than that, I felt a slight gain - you can feel the car pull more :) Sound isn't very loud, but it's a different tone (lower).  Highly recommended at this price and Street Unit's incredibly fast free shipping!

5 of 5 RUST SUCKS May 2, 2010
Reviewer: Eric Brown from Granite Bay, CA United States  
This is a great quality product like all the Street Unit Products I've installed on my car.  I will say this my speed 3 has 23000 miles on it and I installed the pipe today.  It took me 2 hours just to get the stock one off due to extreme rust!  However once I got it out it took no more than 20 minutes to put the SU one in.  Top end power gains are great no more drop out at high rpms pulls all the way to red line.  A little louder and definitely a deeper tone.  Make sure you start up the car once you take the stock one off to hear what the MS3 sounds like from the down pipe it will definitely put a smile on your face.
