just called thousand oaks mazda they said both can be ordered now. 70 for intake and around 600 for borla exhaust. They said this wont affect warranty either. They said they have a rx8 with borla exhaust on it already on the lot.

Does this sound right

Only if they can provide copies of dynojet runs to show any change in HP or torque. Otherwise it's just lots of sound and fury...

Will that Borla exhaust make your car sound like a pissed off bumble bee?

LOL, that is funny!

Do they sell those online? If they do, what is the website?

I hate that sound that some exhaust make....LOL!

I have a Borla Exhaust on my PGT and it sounds VERY good. Its got a muscular growl at low RPM and then gets more like a higher pitched F1 engine up top

For the WRX at least the Borla is one of the louder exhausts, also I'm guessing it's simply and axelback or catback so no noticable HP gains. Keep in mind some cars don't react well to intakes, and it will sometimes lower HP, the WRX is that way because it will cause the car to run rich. Since some expect the RX-8 is running rich already I would hold off for some dyno results before getting any type of intake on your cars.

what's wrong with the original exhaust? how much is the borla, how much more will it give you, and do you think the added HP is worth the added "growl" when the car runs very quietly for the power it produces?

just curious...

thousand oak mazda 1 805 371 5555 service dept. I dont know website. They said hp is 5 to 10.

for one thing, it's huge and heavy if not also overly restrictive (y'know how quiet it is?? that's 'cause it absorbs a whole lotta energy out of the exhaust gasses... not conducive to highest performance).

I have a GReddy catback on my Probe GT 94 - I liked the sound and performance of it alot. I would however be very cautious about anything yet for the RX-8 A free flowing intake and exhaust may make more HP on the top end at the expense of torque.


The Probe (and maybe our RX8 also) have the variable intake runner - Longer more restrictive intake for low rpm torque, and shorter route for high rpm HP.

If anything - I would love a mod that gave extra torque, even at the expense of some HP if needed.

A chip on the other hand for the RX8 to recover the detuning I would jump as asap.

so where is the info for this "items?" it is only words, there isnothing at the borla's oficial website that states an existing piece for the 8 ... post some links!

yes,please post some links or if borla reads this i want more info.im going to save my 500 check card from mazda to get a proven catback system as long as 5 or more hp come with it.

sorry no links, I just called thousand oaks mazda and spoke with scott in service becuase another thread said they had info on exhaust and intake

actually on my Probe the Borla produced more Hp AND more torque.

They used the correct size piping rather then some companies just throwing on a 3" or 3.5" for bragging rights which usually lowers torque because its too large. Borla always seems to do their homework before releasing something.

I just replaced the exhaust on my Mazda MX5 (Miata) with a Borla. The Borla is slightly wider, lighter and has better flow than the stock exhaust. It's also louder, but not so loud you can't hear the stereo. Combined with a Cold Air Intake it's definately given a good boost to performance, although the CAI contributed most to the performance gain. Only problem I've been told with Boral, is they don't use resonators (although not sure about the RX8 one), so you might get a bit of resonance when cruising at certain RPM.

again.. as i said to the "turbo kit has landed" thread, this has become a bla, bla, bla thing as well, if these items existed it would be in the website of each company.. but surely enought there no such thing and no other links.. FACTS gentlemen, FACTS can i buy this thing NOW if i wanted to? if the answer is no, then THERE IS NOTHING OUT THERE lets get it straight. enought of the "i saw" , "i heard/read" bs .. my 2 cents..

I want all this stuff too---I'm just trying to get any info or leads I can

i dont know what to buy first

i say go with exhaust first :)

Im going to get the b&b exhaust.

Me too exhaust first... since most people develop muffler first inc. Japan models. We will see more results before a clear favourite to be made.

Dynoing is problem for some people so it is difficult to interpret and compare. Go for big companies like HKS, Amuse, Blitz or my fav RE Amemiya (this is my top choice at present)

Exhaust 1st...just what I've always done though...

There is no point in trying to take more air in if you can't get it out any faster. Do the exhaust first.

Exhaust first. Still not sure who's tho.....

I knew you would say that Hymee

Well I didn't go all the way to Alabama to meet the guy for nothing! Hehehe

exhaust I suggest, cant go wrong there...

go with the intake foist! just said that to be different

Exhaust first makes sense... i just bought the whole package that Rotary performance had to offer. AWSOME heres a sound clip of the GReddy (http://www.rx7.com/RPGReddyRX8exhaust/soundmovieclips.html)

I have the RP midpipe and Greddy Catback also, and man is this beast freaking loud. I am going to get a highflow cat just to quiet it down a bit. It is really really loud. Um just my opinion of course, but I define loud as I can hear it alot while cruising and listening to music, and that is with the windows up.

I have just installed the rotary extreme intake, but don't have any exhaust yet. I think it doesn't matter which one you install first if you going to get both.

I think that you would get greater enjoyment out of getting the exhaust first. More $$$, yes, but you get to see those tips and hear that rumble everytime you get in the car. I am very happy with my RX8Store Exhaust. Great price and sounds awesome.

My own opinion - I would do exhaust first.

My other opinion - I wouldn't touch the intake for the time being.

Cheers,
Hymee.

$600 is A LOT for a Domestically produced mediocre exhaust system. Borla is made in USA and that price is a lot over the price of a true JDM Exhaust system + shipping.

I got my GReddy SP Exhaust System for $500 !!! With everything straight from Trust Japan ! Never ever buy anything from dealerships unless you have no other alternatives.

You don't think the tips on the greddy sp are too big aren't they like 110 x 120 mm whiel the piping is only 65mm. How much HP does that give you?

One more question. If you get the turbo kit that trust has for the rx-8...will the 65mm piping be enought for it? or would you need to get a different exhaust fo rthe added power of a turbo?

We all have true JDM exhaust systems on our cars already.

Of course, that's using the term "JDM" in it's proper, original usage, which means original equipment supplied by the vehicle manufacturer on the Japanese market version of the automobile. Since our North American RX-8s have the same identical exhaust system as the Japan market RX-8s, the exhaust is definitively JDM.

Now if you want to use the lame, corrupted usage of the term "JDM" to mean anything produced by a Japanese aftermarket company, then... whatever. It's NOT JDM, it's Japanese aftermarket. Just because it's made in Japan doesn't make it automatically JDM.
