Out of the last 500+ miles I haven't heard any rattles from the exhaust. In that time it has also had the chance to open up a bit and it sounds & looks (flames) even better. One of these nights I'll have to setup the camcorder again and try to catch the fiery bursts that shoot out of the tail pipes. :D

Bottom line: I highly recommend the Borla exhaust!

 

I really suggest waiting for the racingbeat exhaust and some of the other manufacturers to come out with their exhausts before you buy. Everyone seems to be jumping the gun on the borla. What is another month or 2? Let some other people get some longer term impressions and wait until you get to hear some competition. my 2 cents.

 

I have a borla for my miata- this one sounds even better- I have to upgrade!

 

if your car does break, and the dealer will have a problem, the switch it back to stock when you take it in. assuming it still looks stock and all the hangers are there...

 

it cant void warranty unless it caused the problem... its like i have new rims and then boom my engine blows up... if they said it was the rims well then they would have to prove it

 

im waiting on what GREDDY or HKS has coming... just my 2 cents...

 

Honestly... i know Borla has a great product, but how do any of you feel about what Greddy or HKS may have? i mean, is it worth it or is it the fact only Borla has something for the 8? Im all ears.. rx8 gurus, please stand up... you are all being summoned.

 

Those are a bit to loud for me, typically...dunno what they'll do for the 8 though.

 

if GReddy and HKS are promising to release a cat-back system within the next 2 months, ill wait.

 

another thing i wanted to add.......with alot of the exhaust systems for the rx8 being equal to and above $1K each, the pocketbook is very much an issue to me. i cannot really spend 1200 on an exhaust, and being as the exhaust will probably be dual, its justifiable being that expensive. if the borla can perform almost as good or just as good as the other brands, ill take borla anyday.

 

Some very professional tuners make their own exhausts, including building the actual mufflers from scratch. This can be quite expensive way to go, but you can probably develop a very unique and personalised result.

It's a budget thing. If money is even remotely an issue, skip it or go Borla. (I'm not saying the Borla option is "cheap" in quality, I'm just saying it's very well priced).

 

HKS is typically loud, but Greddy has many exhaust that are below the 95dBA California limit.

What types of materials does Greddy use in their exhaust systems? Do they offer a warranty?

 

ahh.. i would like to know as well.. that's why i was asking. Perhaps someone might have an inside scoop.. im very impressed with the Borla system, but wanted to give the others a chance to show their product. (BUT NOT TOO LONG... 'cuz the longer i wait, the closer i am to grab the Borla.. hehehe <--- good for you folks eh?)

 

Taken straight from their website.

"With laser-cut, computerized mandrel bent aluminized tubing, thick flanges, OEM style hangers, and a polished stainless-steel muffler can and tip... 3-year warranty"


The aluminized tubing is one thing that really stands out to me. The Borla exhaust is made out of stainless steel. I read a post recently that said that stainless steel retains more heat and that helps to increase flow. That sounds like a good thing to me. Plus the Borla has a "Million Mile" warranty.

 

Where can I get the Borla exhaust system in Toronto, Canada...also what is the cost in Canadian price?

I can't wait to hear the new sound on my 8 and to have it spits frame.

Has anyone confirm increase in mpg?

Thank you all!!!:D

 

I can't really compare MPG to the stock exhaust because my driving habits have temporarily changed. It seems that my right foot is connected to my ears and I love the sound of the new exhaust. So my average MPG has recently dropped from 18 to 16 with the new setup.

Don't blame the exhaust, blame my lead foot. :p

 

i dont want to jump to any conclusions.....but most dual exhaust systems offered by greddy and hks are around 800+ dollars. im assuming the rx-8 will be the same or more.

 

Those other companies wil be releasing their poducts in due time. Some after SEMA. The companies also carry some type of warrenty. Depending upon how well the RX8 does in Japan as a tunner car will have a direct effect upon the aftermarket performace market world wide. That's the bussiness end of it. The larger companies like HKS, GReddy, Apexi, etc may take alittle more time since they usually need to change things in production like tooling and they will service thier own patrons first before the US. It's a good thing that american companies are stepping up to the plate and delivering because it adds more variety and competition to the market and as a consumer, competition is good.

 

The full stainless construction of the Borla should last longer, and be lighter as well.

One thing about GReddy...their Power Extreme exhaust is almost always voted as one of the best-sounding for the RX-7 in every poll I've seen. You have to be a fan of the giant tip style though, because at least on that one, its frickin' huge.

I looked at my WRX pipes and they seem sooted too. I have to look under my other cars to see the tail pipe and was wondering if this is why the RX8 is more easily seen; I do not have to bend over to see inside the pipes.

 

Maybe because of the design of the tips makes it more visible???

 

That is what I was trying to say, thanks.

 

please post video of flames

 

The weather for the next couple of days looks kind of foul (rain/snow showers). It should clear up for the weekend. If it does I'll try to get the flames caught on video.

Has anyone else seen flames with their Borla exhausts?
