Compare in Hp gain, Sound, Looks and Performance.. This will help alot of people to decide where to go....

I'd like the Greddy to say TRUST.. the name sounds cool.. TRUST :) Besides, I liked the low rumble of the Trust exhaust system I've had in the past. Quiet when it needs to be quiet, loud rumble when you want to rev it up.

Would like to see a dyno on the new one on an 8 though... hmm anyone with stats for these two exhausts?

I heard that the Borla gives you more hp, is that true?? do someone know that for sure??

here is this Video and Sound of the BB http://www.bbexhaust.com/av/rx8.html

the B&B exhaust is nice...sounds good..makes a little more power than the borla...but more expensive...B&B also offers a straight through test pipe replacement for the cats...huff over at vivid dynoed about 12hp or something close to that over stock..

well i find out the BB is 699, so is not that bad...:)

The quality and finish of the Greedy is far greater than the Borla. The Borla looks like if they got a "Flowmaster" muffler and adaptered it to the RX-8.

well is 50-50 so now whos the winner..:)

I'd say if your car is a show car then B&B, Greddy, or RX-8 store will be the better choice. They come entirely polished, whereas the Borla does not. If you are not going to be putting your car in shows where people will be looking under your car, etc. then choices become a bit more difficult.

Performance wise... from what I can tell they all vary only a little... so no matter which you go with you'll win here.

The Greddy looks good in the pics and TRUST is good stuff. But those tips look a little too big for me. Reports are that there haven't been any plastic melting problems from the larger tip size, but I wonder if it will become an issue if anyone goes to Canzoomer's stage 2 (increased exhaust temp). For some the look of tips that size is a bit of a turn off. Will this tip size fit ok with all bodykits?

Since I've never owned a Porsche, so I know nothing about B&B... but Huff seems straight and the pipes look good in all the pics. The tips are big here, but from the pics it doesn't like it will raise the same concerns as the Greddy.

Borla... having been a long time Stang fan and owner (father and son thing) I know the name Borla. It has been used often and had great reviews from various muscle car magazines. The reports here have been excellent for it. Downs... well a lot of people (at least on this board) are going to have it. Maybe you want to be different...

RX-8 store wasn't mentioned yet. No dyno figures yet, but they seem to be good. From the pics looks are good and after seeing pics in this thread... http://www.rx8club.com/showthread.php?s=&threadid=18569&perpage=15&pagenumber=2 I'd say that it's pretty sharp...

Results.... I'd like to hear all of these side by side or hear from someone who's heard 2 or 3 different ones. I lean towards Borla or RX-8 store, but I'd vote for the lowest sounding of the group.

Welp, I have heard the Greddy, and the HKS live. To me the greddy sounds a bit nicer and I am happy with it. After I get the stage 1 I will update on the tips/plastic issue, but so far it hasnt been one at all. The tips are large enough (and they have a minor opening in the rear to allow air in) that they dont heat up to any serious degree. of course that will change, but then it might be worth investing in the exhaust finishers.

well Japan 8

that was a real good rewiew you did thanks for that, RX-8 store and B&B is my last pick so here we go...:)

I'll throw out the RX8Store as my choice. As if you didn't see that one coming. :)

RX-JImenez - I think that everyone will be a tad biased towards the exhaust that they have purchased; which I'm sure that you already know. Some people will buy an exhaust just based on name recognition alone regardless of price and that's their choice and there is absolutely nothing wrong with that. Others will purchase the first one that they come it contact with because they are able to actually see, hear, and touch it.

I am extremely happy thusfar with the choice that I made and when you finally make your choice, regardless of which one that it is, I know that you'll be happy also. I would tend to bet that there isn't one person (or maybe one) out there that has purchased an aftermarket exhaust that they want to return because they're not happy. Best of luck.

I say GReddy... best $500 spent! Plus GReddy is a reputable company with a degree of quality that I demand, and my standards are quite high. Noticable performance gain, looks decent, and sounds great... Sweet spot around 4-5k RPMs... when the other ports open up. Just my opinion, HKS is asking too much, but u cant go wrong with HKS.

You should also look at the Rotary Extreme exhaust, it looks to be the best flowing design of all so far. But I'm very happy with my Borla too.

The reason why Borla is not fit and finished like the other exhaust because they said its useless and would jack up the price, this is why borla is cheaper than the other exhaust

Is there one exhaust that seems to fit better than others? Which one uses more of the original holes and what-nots from the factory exhaust. I want a good exhaust without alot of crazy modification and rig-ups.

I'll second that!

I am leaning toward Borla though

They all slip in pretty good. The greddy tips fill the exhaust holes in the rear bumper more, and I like that.

Silvertrigger and Jeff - Like Genom said, they all will slide into the current configurations with no additional modifications. Most are bolt and go. Some folks are doing it themselves in the matter of couple hours at most.

All of the aftermarket exhausts for the RX8 are carrying a 3.5" to 4" tips and they all seem to fit equally as well.

Well, with that questioned answered, here's another one. I've read where some people are getting the exhaust finishers to protect the plastic around the exhaust from increased heat. Do most of the exhausts produce that kind of heat, or is it only when combined with something like a CZ1. So, if I'm getting exhaust only, should I get the finishers as a precaution?

like success07 said...
i am kinda biased towards GReddy, i have liked the way their exhausts sound in the past. BUT I am looking for other opinions.

Does anyone have the greddy so they can take pictures and a sound clip? that would be appreciated.

SilverT - IMO, I'd pass on the exhaust finishers. I have them and I convinced that I wasted $200+. You can't see them unless you're at just the right angle and they're a pain to clean with the aftermarket exhaust because of the bigger tips.

Shocka - Do a search and something will show up. I've heard it, so I know its out there.

The exhaust isn't hotter with the Borla or Greddy but the larger tips put the heat much closer to the plastic. I have the exhaust finishers (yes they are harder to clean with the aftermarket exhaust) but I took them off to clean once and ran the car -- I could smell the plastic getting hot without the exhaust finisher in place -- I am going to keep mine on.

is there an alternative to avoid the heat confronting the plastic besides adding the exhaust finishers?

should i install the borla exhaust a bit higher?

I am sure others have the Borla (or Greddy) without the finishers and have not reported a problem.

You can't install it any higher -- the aftermarket exhaust tips leave little room for adjustment.

If you are planning on getting a CZ Stage 1 or Stage 2, I would suggest just getting the finishers -- CZ has reported higher exhaust temps that stock -- I think he melted the plastic around his stock exhaust while testing his unit.

Im still leaning twords the B&B if you look at their dyno graphs they are so impressive to say the least. The sound is awsome perhaps a little too loud though and the HP and tqyou gain at 5-7k is just extrmely good. As for the looks it couldnt get any better IMHO. If Vivids goal was to gain the trust of the RX8 community by being seen as a passionate no bullshiat type of fellow willing to provide awsome customer service I think hes succeeded with me.

I dont like Greddy much since my RSX and what other owners there had to go through. The Greddy exhaust does sound nice on the clips I just think the tips look a little too big for my taste.

The Borla I dont really like at all after I saw the one at the auto show. The way the exhaust is made there is a rounded part in the tip that collects lots of exhaust soot and it looks relaly nasty even at the auto show. The sound I must say is very nice there is no way to dispute that. The price is awsome as well. When they made the borla for the RSX It was the first one out as well maybe thats the market of the Borla exhaust the eager beavers. It made good hp and looked very decent indeed. So this is very consistint with this exhaust as well.

Hks I have no experience with really.

The RE Exhaust looks awsome and sounds great. But we still know too little about this I feel.

Racing Beat looks good .....thats about it really I wish we had more info on it. Im still waiting on them before i get the B&B. Only because every other 7 owner ive talked to even Miata owners tell me wait for Racing Beat. So here I wait. Whats really awesome about racing beat in my opnion is they have a very awsome history built upon the rotary. They have been there the whole time seen the changes and I assume can see where things are going. So I just cant count them out. I just hope the marketing angle does not interfere with the goal of power.

RX8 store would be my third choice because of the sound the pics ive seen look great.

In the end I believe the best exhaust will come from those with a passion for what they are doing. Sometimes

Oh crap I missed the whole point!

On that note Id get the Borla if it was out of the two It sounds so nice and the Tips dont seem as large as the greddy and Mr Borla does show that he cares about his products that means a good deal to me even if he was just going through the motions.

oh ok, im not planning on intalling the CZ stage 1 until i complete my first oil change. I'll probably order a pair and install them, thanks

I have the greddy.. and i love it.. Its much lighter than stock but i didnt weigh it.. but i noticed it was much lighter..

Its not to loud but also when you want to hear it you can...
finish is nice! Ive been running it with the COBB AP and the exhaust temps have yet to melt my plastic.. even on 2 hour trip.. or even dogging it hard.. had it for 2 years now and its GREAT!

it has a Cool golden color wthat goes well with my WWP if you want pics i can show you how it looks just PM me and i can email.. i dont have any sound clips

haha.....over four years later the thread is revived

wow this is fairly close to the biggest revival ever... although i recall someone reviving a thread from like 5-6years ago once.. only a couple posts by the first few members... all gone now too.

dont waste ur money on exhaust finishers theyre just show theres a thread about them.i have the greddy sp2 it is lighter than stock and the tips are bigger but you do get use to them and no it doesnt melt your rear bumper i have had mine on for about 5 months now and no problem what so ever
