S2 owners with single exhaust
 

Thinking about going single on my 2009 rx8. Wondering how it looks with the s2 rear bumper. Pics would be great.

HUH?

I don't know any S2 owner that has gone with a single tail pipe (how old are you? :))

IF you go single outlet you will have to fabricate a cover to go over the non used semi circle hole in back lower Bumper...let alone the main silencer reconstruct or replacement.

BTW: Welcome to the club:)

I would think it would look the same as the S1. just look at some of the pics and photoshop one side out.

I'm looking in installer the HKS single exaust cat back on my R3, I wonder how its going to fit through the original hole, will either need to cut in it or it would hang lower, well see in time, I should be installing this spring, if you still need pic Ill get you some

Thanks man im happy to be part of this forum...by the way im 25..

Thats the same exhaust i was thinking of going with. If i get it done first ill post a pic for you lol....

It should fit fine, just use some adjustable exhaust hangers. It might hang a little low but there is no "fitting it through the hole" since its more of an arch than anything else. Other people have had luck with s1 exhausts by doing it that way.

Ya I was getting some adjustable hangers for sure, I've read around that other cat-backs made for the S1 originally wont fit unless they are set lower at the rear (with the hangers) I saw pics of what they look like a they go out pretty cheap on eBay.

I don't want to hi-jack the thread, but if anyone knows what would be the best mid pipe to use, I heard that the racing beat is the smoothest, and the agency power too but gives allot of droning, and would any one recommend going strait pipe?

I get no droning at highway speeds with the ap midpipe, 65 to 90 was perfectly fine. This is with the stock exhaust mind you, which gives off a rasp/rice sound at about 4k rpm when you get on it.

The best midpipe on the market IMO is the BHR one. You also pay a premium price for it though. The Ap midpie can be had for $216 shipped still I think. I have been told the packing inside it will eventually get eaten up and the sound will change but I have not noticed it yet.

I would agree, Charles (Ray) from BHR did extensive testing to the mid-pipes on many brands, and his BHR came out on top sound and quality wise...so a good move to BHR.

There is by Part Number a difference between Series 1 and Series 2 (CAT Pipes, Manual and Auto), as is with the entire Exhaust (due also to the Rear Muffler outlets handing lower than S1)....IMO OEM CAT Pipe difference is probably due to emissions as it is considerably more $$ than S1.

Has anyone actually fitted a BHR Mid-pipe to a Series 2?

It should fit fine if its made to fit the s1 exhaust. The agency power midpipe is made for s1 and bolted up perfectly fine. I did have to go buy some new bolts for both ends though. The bolts that connect the cat to the rest of the exhaust(springy ones) were not long enough for the install.

If you still need it!

Damn your exhaust hangs low. Ever hit it going over speed bumps? Are you lowered?

No, never hit anything and no, I am not lowered, I ended up buying different exhaust hangers because with the stocks one they burned the shrouds.

I had this built at a import performance shop here in tulsa oklahoma.

Doesn't that fart-can burn your bumper?

Fart can? Really dude... No it doesn't burn the bumper. Not even a little.

wow that is all kinds of awful.

oh ya that shit looks so bad

Racing beat
 

why do you want a single exit exhaust so much? Is less weight your goal? my personal opinion is that dual exhaust looks better. If you want the single exit look the HKS high power is good. or you can get somthing like these guys that have posted already. I went with the Racing Beat exhaust and its great!

there are 3 groups here:

1. the ones trying to save every ounce of weight and performance
2. the ones who want it for the sound
3. the ones who want it for the looks

based on the pics i can tell you that no one succesfully accomplished #1, and only 1 person accomplished #3 ... can't comment on #2

they all look like fucking garbage! Single exhaust do not look good on an S2 especially on a R3

Mine saved 14 pounds compared to the stock. It's barely louder than stock, which was an important requirement because this is a daily driver. It's basically what Isley won...how many national championships with? Sure, I could replace it with a turn-down for the ultimate weight savings, but there's no way I'd drive it on the street like that.

sure you saved weight, but you failed to address the other half of what i said ... it would be interesting to see how all of those bends are affecting your exhaust flow.

Here is my single exhaust

Paimon: by "all of those bends" do you mean the two bends that follow the path of the stock muffler system? I'm not too worried about them. Maybe they look tighter to you in the photo than they really are. They're both mandrel-bent 2.5" diameter pipe.

Yea it might be the pic, it makes it look like you have almost a 180 bend going to the muffler

Here's mine. I've used photoshop to close up the unused tip cutout, but that's how I'm going to have it shortly.

How long have you had the exhaust install CustomMSP? The tip seems really close to the shroud and looks like it will eventually burn it possibly.

Just a day, and it already has.

Hey CustomMSP, what did you do to fill in the missing shroud? Also, My Turbo XS exhaust is probably about as close to the shroud as yours and I have barely any burning after 6+ months. But your exhaust probably gets hotter since it's a single exit.

That's just a photoshop. I'm going to go to body shop and ask them to work some magic using the images above. Shouldn't be too difficult for them.

You can buy some cheap hangers at autozone that are longer than the stock ones and work very well. If you autox or anything of that nature you should probably go with the stiff poly hangers but the cheap ones have worked great for me. I think I've had my hi-power for about a month now with no melting and no scraping on anything.

I appreciate the heads up. I actually already am using longer hangers, 3 on each side. It's not recommended to drop the muffler too much as that places the whole catback at a large offset which might cause undue stress on the rest of the exhaust system.

It only dropped it about an inch or so I think, but it was enough to make it so it didn't burn. I didn't notice any stress on it from twisting when I put it on. I think it is at almost the same angle it would be on an s1.

That's good.

Well put and yes that R3 has a fart can.

Id say who cares for looks. Function over form. Go single, lose the weight. 2 gains instead of one

I'm think of picking up the Apexi hybrid megaphone dual tip catback system. Does anyone have any knowledge on this exhaust system, fitting, sounds or quality?

Thanks

Seeing as that is a dual tip exhaust, nobody in the single tip exhaust thread has that system. Sorry bro. :smoker:

Also, you made me use my first post to this forum to say that. *Sigh*....I blame the internet for my actions.

I broke down and acquired a used HKS Hi-Power. I have modified it to fit and I am quite happy with both the sound and weight savings. Pics when it stops raining.

The used HKS I bought didn't have the adjustable tip so I made my own out of some 4" piping cut on a 30 degree slant. With the stock midpipe, it sounds incredible and doesn't have enough drone to bother me on my commute. I took a video, but the camera mount rattled and ruined the otherwise excellent sound. I will fix it and take another as soon as I can.

i hate to revive an old thread. but ive owned the HKS hipower exhaust twice. honestly it does look a little goofy on the car that should have twin pipes but it serves its purpose pretty well. it sounds alot better than most exhaust systems out there and is a bit more affordable. and on the S2 it most definitly will save you a decent amount of weight. the only exhaust systems out there that i believe sound better are the HKS legamax twin pipe, or the RE-amemiya dolphin tail. also the Greddy sp2, but im not sure if they make that anymore (dont quote me on that, i could be wrong) but all 3 of those are in the 1000-1200$ range.

all in all, if can get one/want one, get it. you wont regret it. plus it should help you save for a good midpipe if you were so inclined in the future.

2009 rx8 r3
 

Has anyone used the Race Roots single exhaust system. Is it any good? Any problems with it? I know it's been around for a while now but I'd like a bit more sound from my exhaust... I know exhausts don't make much more power for the rx8's so with that being said does anyone have information????

Lucky you.

I actually own it on an R3, and i had the original one on my S1. the sound is good. not throaty like borla, sound like F1 at high rpm.

The one that i had on the R3 is single side with back exit tip. this i HIGHLY RECOMMEND.

the downward tip sounds awesome at low speed, but you will have to have earplugs for highway driving.

You also may need to cut or bend the heat shield to clear some hanging area if they didn't change it.

Finally got ahold of race roots and they said their not making them right noway. .. so that leaves me with HKS single exhaust what does everyone think I found a few video clips sounds good to me, where's a good place to order performance parts from found a place called lightning tuning$477 + 9.00 shipping ... but also found others around the 560 mark plus like 30 shipping and all that ... also does the R3 use a different exhaust set up the videos I found of stock exhaust sound a bit quieter then what mine sounds like I guess it could be the camera ... Maybe

Current exhaust sound
 

https://youtu.be/HbXAqe6BQSg my 2009 rx8 r3 :) don't judge getting used to this whole youtube thing lol

I love my HKS. I took some video like I said I would, but the camera mount rattled badly and ruined the sound quality. I have gotten nothing but compliments on the sound and every time I start my car and get to hear that sweet noise I thank myself for going through the trouble to install that thing. There is no HKS Hi-power which will bolt up and fit correctly. Yes you can attach it, but the piping hangs down and the tip doesn't sit right at all. I bought mine used in order to save enough money to modify it to fit. I started by cutting the axle-back flanges off and replacing them with a v-band. This allowed me to use longer hangers on the muffler, but the stock hanger on the pipe. This lined up the exit well enough, but mine came with no tip and I had to make my own.

Like I said man. The hks is a pretty bomb exhaust. I love the sound it makes although I rarely get to hear it since I put I'm my midpipe (non resonated racing beat midpipe). That crap is LOUD. Just like I put in my last post. If you have the money and the means hop on it. You will not regret it. You can it off Amazon nowadays too if I remember right. And no, before you search, the s2 exhaust setup is exactly the same as the s1. The only difference is that you will need longer rubber hangers for the tip not to melt your plastic shrouds.
