THis system sounds really good. It doesn't fart like other cat backs, it has a smooth, nicely toned humm that can get pretty loud at high rpm's. I love this product.Its not too flashy, but looks damn good on my accord.

Takes a while to warm up. After ten minutes, it really kicks in and rumbles a sweet melody. Sort of plain looking.

This system is really good, and sounds even better w/ a greddy header. My CAI from AEM makes for a good match with the Sp. All in all, it sounds great, isn't too expensive and is worth it.

Quiet, deep

maybe a bit too quiet
and hung down to low, i need to pay $40 to move it up 1.54 inches

best are mugen twin loops, cost like 1k
the second lines are greddy, apexi and tanabe
greddy and apexi better than tanabe coz tanabe sounds bad
but apexi looks better
but for the sound, greddy is the best

stock sucks, Tanabe sounds like lawn mower, do not get tanabes

Very nice sound, not very loud, intake is sometimes louder than exhaust from inside the car, anyway. Clean, simple look, although a little bit too plain, it does however hide it's real intentions from cops. Bolted on very easily, perfect fit. Nice performance gains when combined with my AEM CAI, DC Sports 4-2-1 Header, and SP Exhaust. Get loud when you acclerate really hard, but VERY deep, low and smooth, like a sex machine.

I wish the tip kinda could have been flashier, it is really really plain looking. Lost some low end, but not much. Other than that, it's pretty damn tight. The price. Man, that price is just hella expensive, it's ridiculous. But I guess I'm kinda dumb for buying it at that too.

Get it if you a low, deep smooth performance sound and decent power when combined with some other mods. It is truly a great system, one of the rare quiet ones out there on the market. Loud when you want it, quiet when you want it, whatever you want man, it can do it. Highly recommended, IMO GReddy makes THE BEST exhausts, nothing else can compare to the line-up of exhausts GReddy offers. Go GReddy, you can't go wrong with them at all.

Tanabe Racing Medalion. The Racing Medalion is an incredible system. Way too loud though, I mean like the noise got to the point where I felt bad accelerating from a stop light cause I was giving people headaches, and that was without the CAI and Headers, that sucker is loud, so is the Apexi N1.

This has an awesome deep rumble to it which is hard to imagine with a 4- banger, but believe it! It has somewhat noticable power gains, and fits the stock body wo any problem.

It was a little pricy for me but after recieving it it was definately worth the price! The power gains aren't that noticable.

Overall I love the system! Sure it was a little pricy, but like I said, it's worth the cost. I absolutely love the deep sound it produces, especially when you get on it. It is nice and throaty and quiet when you are just cruisin`. I definately recomend this system to anybody who wants an awesome sound and somewhat noticable power gains.

Stock exhaust. Almost anything is better than that! (But especially the Greddy)

-Low Deep Rumble
-Quite When Idle
-Quite on the Highway
-You can control if you want it loud or not
-Polished Stainless Steel (Very Shiny!)
-Looks OEM'ish so It won't attract those boys in blue

-Didn't feel much or any power gains

I definetly recommend this product because it looks OEM"ish" and it sounds GREAT! I love the low rumble, unlike those other RASPY exhaust systems like the Apexi N1

Looks tight, love the deep throaty sound, increased power and acceleration, looks good on the car, Greddy all the way!

nothing

The Chikara i had was WAY TOO LOUD esp. on the highway. The Greddy offers a deep throaty sound in city driving to turn heads while it's relatively ear friendly on the highways, hp gain was felt instantly, esp with my weapon r dragon intake. hopefully, a dc sports or airmass header will accompany it accordingly.

Chikara Hedman Headers muffler plus tip

The exhaust has a nice deep rumble when you work the engine. However, it's very quiet on freeway driving and barely noticeable.

Almost no additional horsepower felt.
The tip bumps my bumper during hard acceleration.

This exhaust has been around for awhile. It fits well, not perfectly, but better than some other brands out there. It doesn't hit my Si swaybar.
However, if you seek more horsepower, forget getting ANY exhaust (speaking for Civics). Get header or Cold air intake instead. If you want look and nice deep rumble, this exhaust is for you. It emits an "expensive" and torquey sound. Pretty good deal for less than $500.

RS/R is quieter and produces more horsepower, but it's no longer available in the States.
Tanabe, probably better fit, but mostly noisier.
DC Sports, similarly quiet, but poorer fit.

Great looking exhaust
Nice sound not too loud not too soft, just right~
fits perfectly

no weakness on this thing. I see that people are complaining about the price. just to make you guys jealous, i got a dual exhuast system for my 99 honda accord for $350! :)

well as i told you above i only paid $350. to save even more money, i installed it myself. well, you really have to do much research to find a place where they sell greddy cat-back exhaust for that price. i had no trouble installing this catback, it took less than 30min to take off the old one and put the new one in. It fits perfectly!! amazing! i have worked with many exhaust, by far nothing tops greddy. so even though you might get your exhaust system for $500. it is well worth the money. also, this catback will last you a long long time.

i had a flowmaster before i installed the greddy. let me tell you guys that greddy is MUCH MUCH better than flowmaster.

The Greddy SP exhaust was a small part of the performance package I put into my LS.

- Sounds great, I get compliments from people who don't like imports and say it doesn't sound annoying.
- Good low end power.
- Quality finish.

NONE, I think this is the best exhaust system for Integra's, it makes them
sound totally different than stock and not annoying.

I read other reviews of people who complain of NO power gains, well you have to do the headers ( Greddy 4-2-1 ) and other mods and you will see a significat power gains. I just raced one of my friends GSR ( with intake and headers ) and blew him off the line big time. Also surprised a few 5.0's.

-Everybody stare at this car.

Stock exhaust.

Materials are first class along with workmanship. Welds are flawless and everything fit together perfectly. The rear muffler and big megaphone tip are stainless steel. The intermediate muffler and rest of the system is constructed of corrosion resistant steel (I think ceramic-coated). This is a pretty quiet exhaust with a nice deep tone. However, when you put the pedal to the metal, the car sounds like a highly-tuned race car or jet or something really cool like that. Also came with all fasteners and gaskets.

The price. I shoved over $500 for the system but you do get what you pay.

I paid around $540 for the GReddy at Alamo Motorsports.
