Exhaust: JIC Full Ti
Header/Y-Pipe?: Megan header/Toyomoto Y-pipe
Rating:9.5
-Loudness: 7-8
-Quality: 10
-Overall:9
Comments: Love this exhaust! Sold it but, the thing weighs about 6lbs only!(JIC exhaust) Was really quiet when I had just the axel back and sounded very close to the HKS Hyper/Carbon-Ti but, had the header/y-pipe and custom b-pipe installed and had a much greater effect in the noise levels. Has drones around 70-80mph.


This is a perfect example for those of who wants or is getting a exhaust system...gives you an idea of what you need that fits your needs! +rep to lilboi for making this thread! I am leaning towards a APEXi WS2, HKS Ti-Limited, or a Tanabe Hyper Medallion! Thanks guys for the input!


Exhaust: JIC 505S Ti (full titanium)

Header/Y-Pipe?: N/A

Loudness: 5-6 (has a distinct sound compared to mild/stainless steel exhaust systems. takes about 15-20 minutes of driving to reach its full sound potential. sounds best and very rich around 3k RPMs & also sounds wicked higher in the powerband. other than that is it surprisingly quiet despite its lack of a resonator. no droning or fartcan bullshit.)

Quality: 10 (impeccably perfect welds, full titanium, & high-end hardware. slightly shorter than the stock exhaust. 60mm piping.)

Overall: 10 (JIC absolutely makes the best exhaust systems & components out there...just be prepared to pay for it)

Comments: I only buy exhausts from JIC. I had custom 2.75" stainless piping on my swapped Civic Hatch and a stainless universal JIC muffler...it sounded crazy. Now this system. And once I get my V160 in my IS I'll be going for a SRT turbo. When that happens I already have a titanium JIC universal muffler to pair with larger custom piping. :approve:
Is there really only 3 of us on this site with this exhaust??

Intake:TU snorkel mod, K&N drop in, lid for airbox removed, PLP intake pipe(same as Joe-z)
Motor:Stock
Header/ypipe:stock
B-pipe: custom stainless straight pipe(no resonators)
Rear section: JIC full Ti

Quality:10/10 as mentioned welds are BEAUTIFUL, its all titanium & weighs a hair over 8lbs for the rear section totally assembled.

Sound(albeit subjective) 7-8/10(not as unique sounding as my previous greddy evo2, tame @ idle, but once it warms up you can tell it's not your run of the mill stainless fart-can back there likely from thin walled Ti piping vs. thicker steel)

Loudness(also subjective): 5-6/10 quieter than the evo2, less of a growl & more of a purr, no rasp without the silencer, with the silencer it's damn near stock sounding. was very surprised since the JIC doesn't have a resonator & is an overall smaller muffler

I recently was building my IS for boost but after a few complications I put that on hold and went the bolt on route.
Intake:Aem short ram
Motor:Arp headstuds,Cometic streetpro headgasket,Head has been milled w/valves cleaned up and reseated
Headers/Ypipe:Xerd
Exhaust:Megan N/A catback
As far as sound it has a deep tone but in the higher RPM range it gets a little loud/raspy for my taste but still maintains a nice throaty sound vs the whiny sound I was accustomed to when I had a civic years ago.I haven't tried with the silencer yet so maybe that would help but I figure it won't matter in a month cause I'm going to finally put my turbo kit on instead of looking at it in my bedroom.

I just got the greddy ti-c exhaust catback. very nice sounding, not really ricy at all. Cool look to it with the burnt tip. I recommend it to anyone!

Exhaust: SRS Type R-1 Catback
Header and down pipe: OBX

Took a chance on SRS after being disappointed with 5zigen Fireball Exhaust.
This is a much deeper and throatier sound, and I get compliments all the time.
Does not sound ricey, though it does drone a little around 3000 rpm.

Later on, I installed OBX headers and the car got stupid loud. Luckily, the SRS exhaust came with a silencer, which I now have on.

Great value. I bought it for $180, but now the price has gone up to $260 on Ebay

Lots of different models over this thread. Curious to see where all those models are now. When searching for an exhaust at this moment all that can be found over the net (still don't have access to for sale section on this board).

Tanabe hyper medallion touring
Tanabe medalion concept G
Apexi ws2
Yonaka
Manzo

can't wait to see what's available on the used platform because all I find at the moment are new 95% of the time and they are quite expensive

The Manzo catback is a nice, cost-effective product. It has a decent sound when you're on the throttle, but stock is barely louder than idle. Quality is decent, though I noticed the chrome finish yellowing a little bit after only a few months. :/

Yonaka is just your run-of-the-mill cheap replica brand. Apexi and Tanabe sound nice, though Tanabe is $500+ last time I looked.

Yeah while browsing through this thread I've listened to all videos and soudnclip that were still available on YouTube (some were deleted by the time this thread evolved), and I think Yonaka will NOT be my choice.... There was a video showing difference between stock and Yonaka in every situation (revving in neutral, acceleration from 0, acceleration while driving (from the inside of the cabin), etc and you can't even tell there is an exhaust on that car.

I've personnaly heard the Tanabe Medallion some times ago when trying to exchange my previous Tacoma X-Runner for an Is300 (4 years ago) and I liked it, not loud at all but still noticeable. However as you mention those exhaust new are quite expensive... with canadian money value being low recently they retail over 7-800$ + shipping on eBay (and this is the cheapest when comparing to Apexi ws2, HKS TI and some others.

I'll wait to get 50 posts to see if there's something interesting available on the market forum..... but I think that I'm probably not the only one looking for one so chances are thin to get a used one even here.... might try the JDM shop on the next weeks, maybe I'll be lucky enough to find an altezza aftermarket exhaust

May I recommend taking a listen to (youtube) and considering a Magnaflow straight through muffler.
Model 14851 is a polished muffler with a 4" tip and their most aggressive sound. (competition series) Under $185.00.
Model 14829 is the same as above but is far quieter. (street series) Under $185.00
Model 11235 has no tip and a satin finish. Add your OEM tip or buy one. Under $90.00

All of the above have a 2.25" in and out.

A'PEXi N1 Catback Exhaust

Exhaust: A'PEXi N1 Catback
Header/Y-Pipe?: Stock Header and y-pipe
Rating: 8
-Loudness: 7
-Quality: 8
-Overall: 8
Comments: Low rumble at idle, when cruising there is no drone, at WOT it doesn't sound raspy at all, very aggressive, and deep all throughout the RPM's. It is kind of expensive sitting at 480$ on thmotorsports but it is worth getting. If you are looking for something a bit more loud i recommend getting this catback plus an aftermarket header and y-pipe. The only CON I have is that part of the exhaust is hitting my right rear lower control arm which can be heard hitting it when starting from a stop, nothing adjusting the rubber hangers can't fix though. Definitely recommend this catback though. Will post sound clip up soon.

I bought an HKS Hi-Power muffler a while ago, and I'd say...
Tone: 7
Loudness: 4-5
Drone: 5
Quality: 8

The muffler sounds very good, in a refined sense, but it is not loud enough to notice any difference in idle.
I'm going to experiment with a larger mid-pipe section and see if I can get a good idle tone.
But past that, it sounds really great for someone wanting a little more sound on the highway.
Definately allows you to hear yourself from inside the cabin, but only barely.

I love my magna flow 2.5" exhaust. almost as quiet as stock exhaust with megan header and y-pipe. great for flow and top end power!

Nice. I was looking at buying one, but they are expensive. ~ $700+

Where did you order yours from?

Autohance.com I ordered it from there because they had a magnaflow 10% off coupon code and I believe it will be around at least for another two months. It was one of the first links typing it in on google and clicking shopping. I justified the expensive price tag due to the build quality and diameter of piping matching directly up to the output of my y-pipe. Used a stock civic K24A exhaust gasket from autozone to seal the y-pipe to magnaflow connection, so now i even have a honda part on my build :)

Finally, some information on that system
It's honestly great, the fitment was better than my HKS even. I've went through 5 exhausts since i purchased this car just because I was looking for the right sound. The last exhaust I had was the stock one with my megan y-pipe and header, and it was still a little loud, but not attracting cops. It just wasn't holding power up top with my built engine and I knew even the HKS exhaust was choking the engine's power. Once I went with this 2.5" exhaust, i realized I made the right choice. It sounds as quiet as the stock exhaust with the Megan header and Y and it is the same inner diameter as the megan Y-pipe so my exhaust is finally all the same diameter and it is wonderful for the engines power, I have never felt the top end with my engine build (cams, valves, all internal supporting parts), because I was choking it with such a small exhaust diameter. The megan Y at the merge and the Magnaflow exhaust both have a 2.37" inner diameter, and I feel with my intake modifications, and my engine internal setup, this exhaust truly unlocked the power, and powerband i desired. I could not be happier with the way i engineered this build to all just flow together perfectly. I'm convinced on the stock ecu this build is making over 230whp, with my automatic transmission. The only reason I refuse to tune it is because it is running 12:1 @ wide open throttle with all my mods, and I believe if i leaned it out anymore there would be know way to tell if one or two cylinders would be running too lean (which would be very likely due to our intake manifold and intake ports design), I would rather run a tad rich and have her safe than melt a piston. Sorry for the long descriptive essay of a post, but basically this exhaust with a good header and 2.5" y-pipe along with a built race engine is the key to unlocking power in this car. The reason so many people aren't over the 210whp mark is because their exhaust piping diameter isn't large enough to flow the power. A stock honda civic si uses the same diameter piping as this exhaust, that should explain enough as to how much power can flow through our puny, stock exhaust piping.

Question on the 2004 Sport Design Exhaust

Hey everyone,

Thanks for starting this one up.

Curious to know, (I can only speak on the year and model I own) for the 2004 IS300 Sport Design - it was noted that there was a "Sport Design" exhaust.

I know from other friends that own a stock mid-2000s IS (Non-Sport Design), that the exhaust on my car is in-fact different.

On the surface, it almost looks exactly like the RMM Exhaust I've seen Online- however (Other than eyeballing it) I simply have no idea of really telling.

Can anyone lend some insight as to the stock "Sport Design" exhaust that was offered by Lexus? Were they any additional horsepower gains? Tonal differences? etc...

I have a new Apexi N1 inbound and would be happy to take some video to share for sound comparison.
- I actually love the sound of the stock exhaust but am wanting something slightly more aggressive sounding.

Thanks in advance! :D
