RoadsterGarage MX-5 Sound clips

Today, I managed to get some sound clips of the MX-5 with the new exhaust setup.

Excuse the quality of the videos, and my lack of knowledge on how to edit them!

Yes, I still need to purchase the embedding option, all in good time.

Props to John H for helping out.

It’s Alive!

That right guys, the MX-5 is alive!

I received an SMS 1 hour before I finished work today, it was from Anth, ” the car is almost ready to go”, so excited the remaining hour felt like forever.

Anyway, 4 o’clock finally arrived, and I was out the door, and on the way to Dahtone Racing.

So, I haven’t seen the car in a few days, and I was pleasantly surprised to see how the progress went.

Anth said to me, “we’ll start the car tonight” my eyes literally glowed, the amount of excitement I had was unbelievable.

We had a few hiccups to before that perfect crank of the key, it started!, but was running in limp mode “Oh shit!” I thought, what could it be?

Turns out somethings going on with the Piggyback, it seems to respond on the reds, but when the engine is running it doesn’t respond. So for now we bypassed it to see how it ran … Perfect!

The sound emitted from the exhaust was amazing, it’s extremely loud, yet beautifully crisp thanks to that incredible RS*R muffler. The N power headers really beef up the tone of the car too.

Anthony wanted to make sure the gearbox wasn’t a “dud”, so he went through all the gears and it all went smoothly.

There are a few little bits and pieces left, which will all be completed tomorrow. I can’t wait!

This is how the engine bay currently looks, if I do end up getting the Bomex bumper, I will probably make a duct for the Flow Stack to the passenger side inlet.

Till Tomorrow guys!

RSR In Its Final Stages!

Well the past few days have been pretty epic! Adan came past yesterday and we finalised the mounts and got everything welded.

We then used some Septone engine enamel flat black and sprayed the whole setup. The Results are below.

The complete exhaust all painted. Notice the de-cat has the standard cat shield on it.

Bolted onto the car for the last time, yes we kept the RS*R badge and mounted back in a similar place from factory.

We kept the standard badge and remounted it into a similar position as what it came out of the factory.

It sounds great, and gave a vast performance increase … I really couldn’t be happier.

To have a listen, check out RoadsterGarage on YouTube, or click the link the below. I will try to get a better video up ASAP.

Next I will be completing my intake setup, so stick around!

The New Exhaust

This weekend, Adan and I started working on the custom exhaust.

The specs are as follows,

2.5 inch mid pipe with no cat, 2.25 axel back into the RSR muffler

We decided to make a flange for the De-cat pipe, like the early NA’s. This would be easier to placing a Cat in this section rather than chopping and rewelding the mid pipe.

Adan was rather surprised on the simplicity of the MX-5’s exhaust, And everything so far was gone rather smoothly.

Here is Adan getting to work on making  the De-cat pipe.

At this stage, we have tacked the whole exhaust, it’s now ready to be welded.
Here are a few pictures of where it sits on the car.

And finally, a comparison to stock, the new exhaust ended up being almost half a metre shorter!, you can see it’s also a lot straighter than factory.

Next weekend, it should be all welded and mounted on to the car.

Not too bad for a front yard job eh?

Wild Weekend!

Midday, Saturday the 9th … I set out on a journey to Jannali, to pick up that RSR exhaust that I won on Ebay.

40 degree heat and no aircon dont fare too well I must say, but it was all worth it when i layed my eyes on this beautiful work of japanese engineering.

Exchanged words with the PO, and went on my way back to the Liverpool region.

 My main concern was that the exhaust was designed for the stock rear bumper. Considering i have a Mazdaspeed A-spec rear lip, I was pretty sure the positioning would be off … and I wasn’t wrong, But hey, I wasn’t planning to use the same setup anyway.

Anyway, lets take a look at the condition of the RSR.

As you can see, the rear of the piping has been rusting for a while

No Biggie! we are scrapping the piping anyway.

The muffler is still extremely shinny, which is great!

I took off the stock exhaust and compared it to the RSR setup.

Another thing i noticed was that the silencer was welded on to the exhaust, I was worried that it may have rusted itself in somehow.

It was difficult to remove, but it has now come out thankfully.

Heres a picture of the badging on the pipework, I will be relocating this on to the top of the muffler.

And finally, a few pictures of the exhaust mounted.

I’m not happy with how the exhaust sits, but it doesn’t matter much as Adan and I will be designing a much less restrictive exhaust.

Argh Ess Argh!

As some may know, a rather rare piece popped on AU Ebay last week … An RSR exhaust, what makes this even more interesting is that it came off an NB.

I spotted it when the auction first began, then i forgot about it … until yesterday. I had another look, and I remember hearing the awesome sound the RSR creates on my friends NA, and I thought, that this has my name all over it!

 Never, have I seen an RSR listed on Ebay Australia, so I had to bid.
There was someone else chasing down this RSR exhaust, as the bidding was going back and forth all the way till listing ended, Tonight at 7:44pm AEST, and I won by a nail-biting 58 cents.

I’ll be getting my grubby mitts on this piece in a week or two hopefully.
