why dont you do it yourself? it only took me an hour and 9 minutes.... its very simple. so why waste the money? and yes im stock for now going to work on the ms dual can exhaust.

 

well it took me a little bit more than an hour to install (part of an afternoon ). I did use some liquid wrench on some of the bolts and after i started it the first time, i had smoke coming from the tail pipes and from the engine bay. Now it's smoke free and running like a charm...

I took my car to the dealership yesterday for the engine recall and they didnt say anything about the RP supercat. They just asked me why installed a new one....my car passed with no problems...they just replaced some spark plugs and reflashed it.

 

After talking to a Chris at RP, all confidence is back! Although I had a little tough time finding a muffler shop to install it for me (since I'm in CA and they are worried about liability and legal issues), I am now a happy camper! With the RB exhaust, I can barely tell the difference in sound, that is until it's full throttled. Due to the linear power curve, there wasn't a big difference in feel, but I noticed the the RPM and speed got up much quicker than before! And the bonus was after test run on the highway, I pulled into a parking lot, and I was able to shoot 3 inch flames a few times...

I did get one thing that worried me though....after getting on it pretty hard for a few minutes, the CEL came on blinking a couple of times before going away. Is this anything to be concerned about? Any advice would help. Thanks.

 

yeah. this is definitely a great mod. and thanks takahashi for the info about the dealer. now all i need is my freaken MS exhaust.... =(. hey zglide, on my old 04 rx8 when i floor it really hard in 4th on the freeway my CEL comes on at about 7000rpm (from what i can remember) and does not let me pass that point.... and than it goes away, if thats any help to you?

 

Ummmm...shooting flames? I don't like the sound of that. It's not a straight race pipe (which would be normal) - there's a cat in there. Sounds like the cat got torched a bit.

I'm no expert but that just doesn't sound good to me.

 

shooting flames is normal. mazda tuned the rx-8 to dump fuel into the exhaust to cool down the cat. if your exhaust is hot enough, unburned fuel that hits it will catch fire and when it has enough air and blow flames out the exhaust.

Uh oh.....did I do something wrong? Does the CEL I got for a few seconds have anything to do with the flames? I've read others on this forum got flames out with just a Borla exhaust and no other mods. Is this something I need to prevent?

 

uh.... look up one post.

 

Hey thanks must have been typing same time as you!

 

heh. Timestamps are a wonderful thing.

 

ZGlide: I don't think you should be getting CELs. I got a CEL but I 'thought' mine was related to my pulleys.

 

still cel free here....

 

Yeah but why did it come on? It's been 3 days and everything else is fine except that night why I got on it really hard. Is it something I need to be concerned about or is it just hte mixture was off since it's a new cat? Thanks for any help....

 

Thats happened to me before too, I think its just a coincidence that it happened when you put the cat on. It more than likely is just a random misfire and if it were something to be concerned about it would have stayed on. If it does happen again though, I would check your spark plug wires and make sure they are tight, and then if you are in to doing stuff yourself I would pull the plugs and see how they look, you might need to replace one or more. But I wouldn't put too much thought into it, it really is nothing to lose sleep over.

 

Hey thanks Red...I think I'll just do that and sleep soundly.

 

Installed my on Saturday.. I got no CEL at all so I am happy about that. Also I don't think it's banging against the brace so that good.

The install was a bit of a pain. I almost gave up breaking the nuts on the header connection but after some super human effort I got them. Getting the hanger out of the rubber piece was a pain as well.

Sound is too loud for my linking to be honest. At 4K-RPM it's not bad but it's very loud at 3.5K-RPM, that seems odd too me. I am going to get a professional to take a look to be sure that I have no leaks. If there are no leaks then I'll be adding a resonator or going back to stock.

 

Wow, I've never heard of the 8 shooting flames without a race pipe.

Anyone think damage will result from trying to shoot flames with the hi flow?

 

You are suffering the same thing I am. Is it like a buzzy sound at about 4k? I added a resonator and it didn't make that go away, it only deadened the sound at WOT, which is actually where it sounds best. What I did notice though is that after a few days the sound isn't quite so bad. Also, are you running an aftermarket exhaust? If so, which one? I have the HKS exhaust, and another guy in my car club has the racing beat one, and his doesn't really have the buzzy sound like mine does.

 

I have the stock exhaust. Others have said that with stock exhaust it sounds almost like the stock cat. Not the case for me (Assuming there are no leaks).

Good to know that a resonator is not going to help much. I won't even try that now.

 

agent008 if you decide to sell let me know..

 

If I remmber correctly I checked several exhaust at Seven Stock.

Most of them were cheap thin pcs. of metal. That could be why your getting the vibration from.

Racing Beat is very thick and heavy. It will never rust or vibrate like competitors.

 

Not sure if it's too late or not... but I'm in. I sent them an email already so I guess I'll find out if it's still available not too long from now.

 

Have you ever seen the HKS exhaust before? It is much higher quality than the Racing Beat. Have you ever heard the HKS before? It is alot louder than the Racing Beat. It is fully polished stainless up to the cat, it has the thick rolled edges just like the Racing Beat, but, it doesn't bronze over time. Maybe you should check the pictures in my profile to see for yourself.

 

my friend bought a RB exhaust... I think the guys an idiot... I bought an Agency Power exhaust... I think I'm a haus

 

two questions..... should my stock exhaust be rattling more and more as i drive with the RP?(checked the bolts all tight) and would any of you choose the HKS legamax or the MS dual can for the rp? i'm still debating.... =/
