First Look: RX8 – Power Series Dual-Resonated Racepipe

RX8 Racepipe

The last week has been a lot of fun here at Corksport. We have been working on developing a cure for High Decibel Situational Tourettes Syndrome, which effects a certain percentage of enthusiasts who run a non resonated racepipe in their RX-8.

Our latest solution is a dual resonated Power Series Racepipe for the ’04-’10 RX-8. Incorporating a 140mm primary resonator and a 100mm secondary resonator with 61mm exhaust tubing, the resonated racepipe improves exhaust flow dramatically while keeping the decibels at a level reasonable enough to avoid spontaneous profanity from drivers and spectators alike. Think your racepipe is too loud? Check out this video clip of the Power Series Dual Resonated Racepipe and with Power Series Cat-Back Exhaust on our ’04 RX-8 and let us know what you think:

Like all of our Power Series exhaust products, the Dual Resonated Racepipe for the RX-8 incorporates only the highest quality materials and manufacturing methods.  Featuring T304 stainless mandrel bent tubing, stainless oxygen sensor fittings (one for the stock oxygen sensor and a secondary unit for the use of a Wideband O2 monitoring & datalogging system), T304 resonators and flanges. All connections are TIG welded with 308 stainless rod to ensure good weld penetration and attractive finish on the weld bead.
We’re hoping to get a handful of these systems out on the street in the next month and we’ll keep you posted as soon as they’re available to the public.

We’re also entertaining the possibility of incorporating a high flow catalyst into the system to keep emissions to a minimum.  This will be a 108mm spun metallic substrate catalyst replacing the secondary resonator.  If this is something that would interest you, let me know by dropping me an email.

New Header and Intake for 1.6 DOHC MX3s!

CorkSport has gone back to its roots so to speak. We have been working on developing new performance parts for the MX3.

One of the parts Jason has been working on is a header for the 4 cylinder MX3s, seen below.

We are working to incorporate all of the emissions fittings for the header to make this a sensor friendly upgrade.

The second part we have been developing is an intake system for the MX3 4 cylinder model. The test vehicle shown below is the 1.6 DOHC model.

The intake we have been working with is a bolt in design which incorporates all of the fittings for the crankcase and the idle air control valve.

If you are interested in these parts let us know by submitting feedback on this blog post or contacting me at derrick@corksport.com.

Update: 2010-2013 Mazda 3 Performance Parts

I know this is a bit redundant, but we’re just so excited about these new parts that we thought we’d give you an update on how things are moving along with the new 2010 Mazda 3 parts.

You remember from last blog that I got my hands on a 2010 Mazda 3. It was a 2.0L automatic, but because we had ordered a dual-exhaust rear bumper I was still able to make both a single and dual exhaust for it. You’ll also see a picture of the new SRI (Short-Ram Intake) for the 2010 Mazda 3.

First up here’s some pictures of the single-exit exhaust:

Here’s a couple shots of the dual exhaust:

Finally, here is the new SRI:

That’s all for this time, keep checking back for more updates!

First Look: 2010 Mazda 3

Welcome back!

On this edition of CSBlog we’ll be getting our first look at a 2010 Mazda 3!

We were able to get our hands on a 2010 Mazda 3 sedan to do some part fabrication and testing. The 3 that we got was equipped with the 2.0L engine and an automatic transmission. A couple of things that I noticed about the car right away were that this really is just a face lift, the undercarriage is mostly the same as earlier models. On this revision Mazda did finally make the exhaust system 2 pieces, so no more cutting the factory exhaust to remove it from the car, which is a bonus. This is a short update, but I really just wanted to show you the single exit and dual exit exhausts, and the SRI (Short-Ram Intake) that we were able to develop for it.

Couple pictures of the underside of the car:

Here’s a picture of the prototype dual exhaust I whipped up:

That’s all for now!
