Project RX-8: Midpipes and Install

[@robertkorn]

"All rotaries still running should be exempt from emissions"...This guy for president!

[@TheSlipAngle]

LOL

[@theguy1991]

My 09 R3 caught fire from a clogged cat a couple years ago lmao. Fortunately the fire was put out in time. Just the surrounding insulation was damaged. Still driving it today

[@NateRist]

Racing beat mid pipes are great, but I went with a BHR mid pipe for mine. the resonator is just swirls metal whereas the racing beat has steel wool for sound deadening. The swirled metal in the BHR pipe holds up better over time and does a great job deadening sound

[@TheEnergyDrinkGuy]

Agreed, run a BHR midpipe with the high flow cat and TurboXS catback.

[@ricepony33]

Sounds perfect as is. Nice and subtle, it’s a daily.

[@dannyd7714]

I bought a 1 owner, 9500 mile 2010 R3 in June. Was completely stock. I put the Exoticspeed R1-T catback on almost immediately. Added the racing beat dual resonated midpipe yesterday. Sound is fantastic. No drone. Quiet while cruising, but screams under WOT. car is at 10,400 miles right now.

[@TheSlipAngle]

Awesome buddy! How does it sound chugging up hills in a higher gear?

[@dannyd7714]

@@TheSlipAngle is that a trick question 😂 I generally cruise around 4000-4500 rpm so I'm usually not higher than 4th gear when I'm off the interstate. The exhaust is very docile under low load. At 4500 rpm the car pulls hills easy under partial throttle so it's not too loud. WOT is a different story. It's loud but a good loud. Not a lawnmower ebay ricer loud. It's a beautiful sound. No rasp, no drone. Cruising with my wife we can have a normal conversation with the windows down, radio plays at a normal level, it's the best of both worlds. And the Exoticspeed catback is gorgeous. The mufflers sticking out under the bumper is so pretty. Especially on the S1 if you cut out the diamonds in the rear bumper grille. Mine is S2 so it's a solid bumper.

[@joogullae3456]

So lucky man goddamn

[@Bluebeast2005]

Very nice vid! Super clean car, really digging the header/colors thanks for sharing. I'll trow my vote towards the Tanabe system, more rare, authentic, lighter and yes very nice for DD... but sadly I don't have one... yet. Keep it up!

[@trump-ob5xl]

Yo im here from tommys last video just ran thru your channel and you got some cool content man it'd be sick to see you on his videos maybe

[@TheSlipAngle]

Thanks man 👍

[@Flyingdutchy33]

In the Netherlands we don't have emission checks for rotaries. But our roads are boring and congested so I guess it still evens out.

[@TheSlipAngle]

If you have a still running rotary it should just be exempt by default :)

[@neilobusk]

Phew...Exhaustive work there.... :)

[@sebastienlefebvre9723]

Hello from montreal..ive everything from racing beat..header..resonator catha..mid pipe and 2 racing beat muffler..the sound or just amazing and not too much for police catch me....i love it..i recomand it..😁😜😲 and my check engine never came on..

[@Rellsrides]

Just FYI for future references a “bottle neck” can also serve a purpose as a Venturi and can actually speed up gas speed small engine racing experience huge gains from little things like this and there is a science just around flow

[@wookiefrost]

When does Mazda edit pt2 come out ?

[@joselperez9384]

How you keep it so clean down there?

[@eternitykings4233]

Steam cleaning

[@milliondollaboiibsb4927]

Great video love the channel I own an 05 just curious what kind of wheels you are running they are stupid clean man

[@TheSlipAngle]

Enkei Kojin

[@nIsMoALEX]

I was using the HKS HiPower when I used to have an Rx-8...light weight and not too extreme with the RB dual resonator! You can figure it out with the only video I have in my channel lol

[@TheSlipAngle]

LOL

[@andrewmiller1540]

I will say that is no good at all. I run the hks with a bhr midpipe and saying its loud is almost an understatement. I cant wait to finally install a header on it tho and see how loud it really gets haha

[@nIsMoALEX]

@@andrewmiller1540 it won't change as much as a loudness perspective but much more in tonality...it'll sound gooooood buddy! Damn I miss my 8

[@andrewmiller1540]

@@nIsMoALEX yeah I know it won't be much louder with normal driving and I can't wait to see what it will be like as I already love my exhaust. I was actually in an exhaust rev off at an event called hyperfest and Vaughn gittin was the host of it and obviously the 2jz Supra drift car hitting 2 step was crowd favorite but he actually told me after the event that I had his vote lol

[@nIsMoALEX]

@@andrewmiller1540 ahah that's cool!!! ✌️

[@howzertech2222]

I have a Tanabe Medallion Touring and a resonated midpipe on my FD, which is basically the same engine as your RX-8. I've got a couple of recent videos on my channel if you want to listen to the exhaust. It's nice and quiet during idle, cruising, and highway driving. I still get a good noise in the upper RPM range. The Tanabe Exhaust has a 3" pipe and muffler. The tip is 4" but it is reduced on the inside. I can take a video or some pictures if you want more info about it.

[@TheSlipAngle]

Thanks bud, but the 13B-REW and 13B Renesis are very different engines i.e. Peripheral vs side exist exhaust ports. Plus turbos do a great job of reducing exhaust noise on top of that :)

[@howzertech2222]

Yeah, the exhaust porting is quite different but I figured that it'd give you a sense of the noise. It's a single turbo and it's in vacuum during idle and cruising, which doesn't generate the full blown rotary "loudness."

[@princesssolace4337]

What's the problem when the weight is way down close to the road? It will aid in chassis staying flat when heavy brake is applied.

[@RazorsEdg3]

Also aids in cornering due to lowering the centre of gravity. Reduce weight from top down that's what all race engineers do on all race cars & F1.

[@Alejandro-ej2hn]

I have a megan racing mide pide with a agency power exhaust system and LS7 coil pack conversion kit

[@does_not_matter_91]

Man, did you cleaned this car from the bottom? Why is it so clean!? :D

[@DriveItRyan]

Sounds way more refined 👍👍

[@mazdarx8Greece]

One more like (400) from Greece, take care.

[@Patoaaiight]

Clean rx8 👍! I bought the one you threw away but it does not seal right it haves a leak what about with that racin beat ?? Did it seal all tha way ?? Thanks

[@TheSlipAngle]

The RB unit seals well 👍

[@does_not_matter_91]

Oh and one more question. Doesn't the smell bother you after removing catalytic? I'm thinking about removing mine, but I never smelled rotary exhaust without catalytic, and I'm kind of afraid that it will ruin the experience for me. I don't want my interior to have some terrible smell, but I assume some people online might be overdramatic.

[@arauzmotoring1741]

I’m considering a Fujitsubo exhaust for my S2. They offer the RM01A which in my roadster, can be loud but really isn’t that bad- and it really cuts down on weigh. They also have the legalistic series which may or may not be heavier than factory. Price is the only down side as they would be a good amount more $$ than the RB cat back. Edit* wow the RB mid pipe really made it sound a lot nicer compared to that Ebay unit. Any reason you skipped the Bhr ones?

[@andrewmiller1540]

Probably due to wanting 2 resonators. From what I hear, the bhr is better and will last longer which is why I went with bhr over rb

[@TheSlipAngle]

I wanted the RB pipe to have maximum sound suppression for a daily driver. I'm sure the BHR will last longer due to it's design, but I don't see how it could provide the same amount of sound suppression as the RB unit. Any muffler should be considered a wear item and will eventually wear down.

[@thehowl1689]

What are the plans for that elise seat in the background?

[@TheSlipAngle]

You'll see soon enough ;)

[@jsnismo240sx]

what are your wheel size? Looks good and sounds good.

[@TheSlipAngle]

18x9.5 +30 but I'm running with a +38 offset now and they fit perfect.

[@1sinister80]

I am installing a Turbo XS high-low cat.on my RX8. Are.these any good?

[@jayl9267]

Do you still have that mid pipe? I'm in Connecticut.

[@LethalJizzle]

Have you been using spring bolts on the rear? Just thinking that could be the cause of the crack.

[@TheSlipAngle]

I have not, but the crack was from the hanger ripping away from the exhaust. No issues at the flange.

[@chance170]

What type of midpipe did he put in?

[@NaxRydan]

Great Vid! Subscribed!

[@TheSlipAngle]

Thank you!

[@potatochobit]

does the racing beat also cause a CEL code?

[@TheSlipAngle]

Yes it does

[@domdiaferia]

Would it be possible to get the part number for that double resonator mid pipe?

[@TheSlipAngle]

It's the only RX8 resonator Racing Beat sells

[@jaredobernesser3292]

How far a drive are you from 13492 in New York. Picking up an RX-8 on Saturday and interested in your midpipe that needs a bit of weld. Might be willing to take a ride.

[@TheSlipAngle]

Google maps shows 200 miles

[@TheSlipAngle]

Sorry Jared, we were filming all day yesterday. If you are still interested in the pipe, let me know.

[@jaredobernesser3292]

Yes, still intrrested. I picked up my RX-8 Saturday. I was hoping you didn't think I was just wasting your time. I'm willing to take the ride. I drove 200 miles to pick the car up and I go to Lime Rock Park at least once a year. Give me a text or call to set up a time that works for both of us. Thanks.

[@TheSlipAngle]

No worries. I didn't think that at all. It was just a crazy busy week for me. I'll shoot ya a text.

[@Popes_Projects]

Any chance you’d be willing to ship that mid pipe? My new project is a low budget drift build, picked up a hks hi power used for cheap and was planning to just “gut” the cat but that would be perfect. I’ll gladly pay a little extra on shipping for your trouble.

[@Popes_Projects]

Oh, and great video, love the content and attention to detail 👍

[@TheSlipAngle]

I'd really prefer not to ship it. You'd probably be better off just buying a brand new one on eBay as they are only a little over 100 bucks shipped on there.

[@MrGeocyp]

had a very dronie sound before.. now it sounds nice. gj

[@frankyrx8459]

The rear part is a silencer in rx's

[@supershark9k708]

What’s one of these make with bolt ons and supporting mods ?

[@TheSlipAngle]

We'll find out soon enough. I am just waiting a few parts before we dyno it and finish the tune.

[@curtishall5910]

Where did you get your header ??

Exotic Speed

[@joaquinjorquera9528]

I lov you canal!!

[@23werex]

single exit exhaust maybe?

[@Domas64]

Too much heat and sound

[@TheSlipAngle]

I wish there was a lightweight single that was quiet but I think I am going to need as much muffler as I can to keep this daily friendly.

[@cc3775]

Have you done any cooling mods? Just picked up an RX8 with a rebuilt motor. I just put in an aftermarket aluminum radiator but temps still climb to 200 and above. Cooling fan relay mod will be here today so I’m going that help.

[@vietfattyxD]

There is something wrong then. I'm still running stock radiator and it doesn't run that hot. Did you bleed coolant correctly when adding in the new rad?

[@cc3775]

vietfattyxD As far as I know. I jacked up the front end and ran it with the cap off until it didn’t take anymore coolant and wasn’t bubbling and coolant was coming out of the throttle body. I pressure tested the cooling system and that was fine. Could the oil coolers not be cooling efficiently and causing problems also?

[@TheSlipAngle]

I am still running the entire stock cooling system as well with just routine maintenance. Have you changed the thermostat? If so, was it an OEM? Check to see if you cat is clogging. That could potentially cause the engine to run hotter.

[@cc3775]

Garage Quinn Motors haven’t changed the thermostat yet as I figured that would have been done with the rebuild. It is next in my list though. Also though the cat would be good since it just passed emissions testing but maybe that doesn’t matter?

[@andrewmiller1540]

Yeah you gotta another issue than radiator. Im still completely stock cooling(and will be until I turbo) and have never had any issues with overheating although the secandary fan will almost always stay on for a while after beating on it in the summer. Heat soak was a lot less once I flashed my ecu and out aem intake on tho

[@isaflyintype1]

a video for TPS itb tunning maybe? ;D

[@jonathanruiz3840]

Have u deleted air pump?

[@TheSlipAngle]

Yes

[@michaeldriver127]

Anyone have experience with exhaust wrap on these? I'm considering this same setup with Racing Beat resonator and OEM muffler. I'm hoping to quiet it even further by wrapping the muffler and possibly the mid pipe.

[@TheSlipAngle]

I think you'll find that with the OEM muffler it's extremely quiet

[@michaeldriver127]

@@TheSlipAngle I'm feeling you're right, and what might be gained is probably not worth the time and money. Thanks for the input!

[@christophermartin1979]

Are you going to dyno it?

I ended up with a Racingbeat. I really don't care for Magnaflow mufflers. They've always been too droney for my tastes.

[@darkmask441]

The Slip Angle I see, I had to run a magnaflow on my 09 RX8 R3, was previos cat was failing and didn’t want to pay $3000 for OEM. Sounds similar to your racingbeat. Anyway, LOVE what you done with the RX8 upgrades and exterior looks AMAZING. Your videos are very informative. Thanks man 👍✌️

If you modify the mid pip will the check engine light turn on? 🤔😜🤔🤔🤔

If you change the flow of the cat, the secondary o2 will pick up on it and report a cel in most cases.

[@MsMilios]

Guys , is Mazda an idiot company . No , isn't . Why I all of you that take you own idemitsu way have all this problems. Keep Mazda semi synthetic oil and change it every 5km . Don't mix with 2 stroke oil , mix with 4STROKE OIL with a thicker one than 5w30 and all those will never happened to you.

[@gandolff1966]

With the amount of rubbish you say, you could have fitted, removed and fitted the mid exhaust over repeatedly.

[@TRIPLE6LORD]

Is it possible to premixed with that midpipe to shoot flames?

[@TheSlipAngle]

Premix has nothing to do with shooting flames. It's unburnt fuel in the exhaust and yes, just about any catless setup will produce that under certain conditions on the Renesis.
