New CES exhaust to 6MPS

[Penguin740]

Well today I got the red bullett back from Custom Exhaust Specialist with the turbo back exhaust fitted. The only part not changed were the stock mufflers (mostly due to cost, but I may change them later).

Many thanks to the hard working boys at CES including 2XS as it was quite a mission to have the downpipe changed. All the bolts from the downpipe to the turbo were seized as the Mazda apprentice...opps sorry mechanic didn't use anti-seize on the bolts. It was also done to the o2 sensor which will need to be replaced as the thread is totally stripped.

However the end result looks like a work of art. Below are some pics 2XS kindly took while it was up on the hoist .

And after.

Initial feel of new exhaust system?

I love the power delivery. It is some much smoother and doesn't fall off a cliff at 5500. The engine seems to want to rev more too.

Power would have to be greater at all points in the curve I would think. It certainly feels faster.

The noise is no greater than standard at idle or cruising speed, which is great. No drone at all!

Then when you put your foot down it gets loud with a gutteral medium pitched sound that certainly lets you know the power is coming.

Not sure if I would call the noise pleasing but will reserve my judgement on that at this stage.

Next step is to have it dynoed to see if the pants dyno is correct.

Great work. Looking forward to the dyno result. Are they putting this into production?

Not sure, they did say it was one of the more difficult jobs they have done. The downpipe was much harder than the 3MPS, so I guess at this stage no. Though if enough people ask.....who knows.

They do have a 3MPS downpipe you can buy, and its easier to fit as its got no 4wd driveshaft etc in the way.

That's not my bench. On the right of the fan is the "Wall of shame" I can post pics of them if you like (send me a PM and I will)

We have outgrown the current workshop, so, we are moving in the new year to a bigger shop.

Looks good.

The reason you don't have drone is because you haven't changed the mufflers yet.

I had the CS system and it droned a little, but since i've swapped to the CPE oval designed muffler system, No drone and more power!

Love to see the dyno results!

[Penguin740]

Can't wait to see a dyno result either.

I will hopefully be able to make the dyno day at chiptorque on the 14th.

Impressions of the mod after a week of driving.

It feels like it has lost a little bottom end power, but the top end is definitely worth the trade off. The car definitely revs so much more freely at the top end than stock. The note of the exhaust I am getting used to and it maintains the stealth feel of the 6mps, but feel I will end up with some mufflers later down the track.
