Looking for actual feedback between these 2 exhaust systems : RB vs Tanabe Touring Medallion - which is louder ? Pretty much narrowed to these 2. Not sure if the RB dual or single tip differ drastically in Db level.
For sure the midpipe scenarios (cat/reso/straight) alters tone so post accordingly. Better yet if some of you are on single turbo. Goal is a beefier throaty sound rather than a high pitched tin sound when on the pedal. TIA
Have not heard the tanabe but I can't imagine anything quieter than the RB other than stock. It has a nice clean tone, which is why I pick this exhaust for every FD I've ever had.
I've had this exhaust with cats and no cats, currently with a straight midpipe, no resonators. It is still a nice clean sound (no raspiness or chainsaw sound) but louder than with a cat. You can really hear the rotary engine sound rather than just a loud exhaust.
I accidentally set off the decibel meter at Laguna Seca at full throttle up turn 5 at 94db.
It's a quality piece that looks nice and subtle too.
I recognize your username over at SF. It's been awhile ! Thanks for the input. I figured in the end, getting a straight midpipe on one of these systems is prob the way to go so the option of adding a reso/cat is there to fine tune the note. Like you said no rasp or chainsaw
I just bought a new Tanabe Medalion Touring last night to replace my RB dual tip which has lost some packing and is louder than I'd like. I decided to purchase after discussing exhausts with a few other forum members. I will document it in my build thread when it arrives!
I did have another like new RB dual tip I decided not to use and sold because I don't like the way it drones on the highway.
The original Greddy SP is also quieter than the RB duals as I have tested both back to back on the same car with a DB meter. At 1000 rpm idle the RB was 4-5 DBs louder. On a single car with resonated Bonez midpipe the SP was in the low 90s and the RB in the mid to upper 90s.
Stock car with only a 3" downpipe and rest factory catback and cat measures around 76 DBs.
HKS Hi-Power from Ebay with full 3" exhaust and non-sequential measures around 107 at 1000 rpms.
I know some of this info is irrelevant to your question but figured it is good info to have. I need to make a thread after compiling more data. When it is cars I own I can set the idle to 1000 rpms to have an apples to apples comparison but can't really ask local FD owners to adjust idle for me to test.

Thanks for chiming in on this, helpful. I actually read a thread on a build you did not long ago and touched on exhaust note and why the SP selection. I can up the DB (at WOT) on this current build of mine as I don't daily or long drive it but don't want the rasp
Feel free to text me again to chat. My old RB is for sale if you're interested.
My midpipe is a custom 3" job with a bottle style Vibrant resonator.
Nice. Do you think it's a bit too quiet with your current MP/Reso with new Tanabe ? Or straight MP with Tanabe would be ideal ?

Love the oval canisters on the FD's though
I have both exhausts and I prefer the Tanabe over the RB. I think it’s quieter than the RB or very close. The part about the Tanabe I like most is it doesn’t drone like the Racing beat at highway rpms. You will notice the Tanabe has a very large muffler and nice build quality. I highly recommend it. It’s also a 3” exhaust and has a nice deep tone. You can hear some sound clips of it on an FD on YouTube. It’s also very affordable and true stainless steel
I also had had a Greddy SP on my first FD and wish they still made that exhaust. I think the Tanabe is as close to the SP as you can get anymore.
No Tanabe experience. Had the Greddy SP and now the RB DT. Both with a Bonez downpipe and Cat with stock twins. Was happy with both sound wise. Both sound great under throttle and at idle. Suspect the SP flowed marginally better just from the type of construction, however the butt-dyno didn't change. The Greddy did drone during highway cruising, but not the case with the RB DT. And personally I like the looks of the RB DT much better. Both are really well constructed with excellent materials.
Unfortunately, the Tanabe is about $600 Canadian. Our dollar is terrible but I've heard the sound clips and I would definitely pick one up but our Canadian dollar sucks.
I ordered my Tanabe on Sunday, 7/1/18, and it arrived before 11:00 AM on Tuesday, 7/3/18! I immediately unboxed it and mounted on the car in a whole of about 30 minutes, the only weird thing was the size of the hardware that came with it which was useless to me but I assume was specified to fit the factory catalytic converter. The catback fit very well with no rubbing and seemed to be of good quality. Without a scale and working by "feel" it is lighter than my old RB dual tip, the construction looked to be of quality but it is definitely less robust than the RB. The flange is not as thick and the piping is thinner, the muffler and exhaust tip did have gussets as you can see in my pics below. One of the things I like the most about this exhaust is the construction of the tip, it is "thick" in size and looks very nice. The word "medalion" is etched onto each side of the tip in a similar fashion as the RB exhausts.
I have not driven with it yet but I love the way it sounds so far. The idle is low and deep and while it wakes up when free revving it maintains the low tone and has no harsh raspy sound. I can converse behind the car without shouting and the sounds of the exhaust under the hood are actually louder than the muffler when standing at the rear corner of the car.
The Tanabe TM exhaust is definitely quieter than the RB duals. Not by much, but maybe 10% less (subjectively)? I have an EFR 7670 application, w 3.5" downpipe & Vibrant UHF cat welded in place of the Bonez high flow cat for the midpipe.
The bigger thing for me, though, was that the RB catback had a bit of a drone at slight cruising RPMs once I went single w the above setup. I was initially hesitant going to a single tip exhaust due to potential unwanted attn. But the droning tone, albeit slight, was enough to push me to the Tanabe exhaust in hopes of an overall quieter setup.
Very pleased I went this direction in the end; quieter & wout any droning. And the bigger single tip has actually grown on me. May eventually go one step further w a resonator or similar combo at the midpipe to get the car down to near stock-level decibels. Still investigating this option.

Do you have any dyno or 1/4 mile numbers with this setup?
I too have the Tanabe... and I absolutely love it.
No droning on the highway, really wakes up on WOT... Clean looks too.
All stainless, so it stays looking good.
Excellent fitment...
I'm on stock turbos, no cats, just open exhaust through this system.
Maybe I'll get a video soon to share.
Here is a sound clip I did at night a few months ago on old
motor. About 17 psi. Straight thru midpipe. Single turbo GT35R with WG plumbed back in. Tanabe Medallion Cat back.
I also have a Tanabe Medalion Touring. I installed it with the stock cats and it was extremely quiet, quieter than the single exit RB i used to have. Then I got a RB stainless resonated midpipe and the pair still doesn't drone, fairly quiet but wakes up on WOT.
I will be tuning this summer at some point with mine. Porter motor and EFR8374 to about 16 psi. Will see what the Dyno says
I was curious of the 7670 numbers. Im likely going EFR again with this white FD and may drop down to the 7670 so I can keep stock fuel(1300 secondaries) and keep it very simple. I would just really like to see 370-390 at 16-17psi but not sure that turbo has it in it.

1cleancym just finished getting his stock motor with a 7670 IWG tuned. He has a sheet you can check out.
