Nice construction, pretty tailpipe. Takes you out of the ricer category of exhaust systems.

Perhaps a little too quiet for some folks.

If you want a little more power from your car but don't want the fart-can herd of west nile moskitoes sound associated with ricers this is the exhaust for you.

I had mine profesionally installed after being delivered from CarDomain. ($410 shipped) The installer at Waukegan Tire (Waukegan, IL) commented that the design looked top notch, it should last a long while.

As for noise and performance, taking off was quick from idle (I have an automatic) but it sounded quieter then OEM and felt alot smoother as well.

I recomemend this product for anyone who is looking for a quiet performance exhaust, or who is just tired of replacing OEM exhaust systems every year on Hondas.

This has to be the BEST exhaust sytem EVER created. Ever freakin Honda should have came with this exhaust STOCK ! It's so FREAKING quiet and when you get on the throttle, it jsut makes a mean & DEEP GROWL. Something like a G35/350Z exhaust tone in my opionion. I also like the way it looks. Very classy and sporty compared to the loud for nothing RICE PIPES.

$402 Shipped! I purchased this product back in September 2005. My friend has the same system on his 2003 Honda Civic Si, and the sound was great. I wanted a Thermal R&D but after research discovered it would be too loud and bassy. I also have a AEM cai. Fitment was perfect, flush, and looks great, The piping sits at a good height, (if you are lowered watch for driveways and speed bumps.) the tip is just under 4" in diameter but it really completes the look of the car even in stock form. It tucks up to the notch made for the stock toothpick muffler but not so close that it is touching or melting the bumper. No rhaspy, whiny, burpy sounds whatsoever no matter sitting at cold idle or WOT at 6500rpm. It just gives a very mellow clean consistent tone throughout the powerband. Noticeable power gains from 4000 and up, most Honda people will notice as well. Low end is a big sacrifice for power with Honda's but I feel I did not lose any at all. Again, perfect system since it is quiet enough for me to drive to and from work everyday (2 hours total) and not drive myself or others crazy, still carry a conversation and listen to the radio, just a great all around system.

-nice sleeper exhaust because fot the focus it only comes with a tip not the canister -very good mid-range power and low-end torque -perfect fit not hard to install -very good welds and bends -best exhaust for the buck

-none what so ever. Perfect in every way

I bought the world sport for my focus because i wanted something quite and i wanted the low end tourque and mid range power the world sport offers. I think this is the best exhaust u can get for a focus the price was good too, 420 shipped, better then then magnaflow and even borla much quiter and still produces the same or more power. Not loud even when i put my shorty header and my off-road pipe or my cold air intake, just made the exhaust note deeper sounds like a V8 in deepness

Great sound... nice and quiet. Nice size tip, not too big

Rubs and squeaks/clunks when going over bumps. The shop that installed it said there were seating issues and needed to be heated up to bend hangers.

I have a 2000 Honda Civic SI. I've had it on for 2 months. The exhaust sound was exactly what I was looking for.. slightly louder than stock. No horsepower gains were noticed. This exhaust has big tubing and rubs on parts underneath. Sway bar link and near gas tank which produces squeaks and clunks.

price, nice quite sound with occasional deep growl, noticable increase in power

not full stainless steel.

I just got my apex world sport II exhaust installed along with OBX-R headers on my 97 civic dx. Already have AEM cold air intake. This exhaust is slightly louder than stock. I didn't want the 'fart' exhaust sound and this is the perfect alternative. I noticed quite a bit of mid range increase and excelleration is much smoother. I installed the system due to a crack exhaust manifold. It was cheaper to buy the headers, cat, and exhaust than to replace the manifold. It was well worth the money.

Very quite, better than stock. This is the exhaust that should have came with the car from the factory

I've been doing research on cat backs for over a year. I needed a quite performance muffler due to my kids and wife. I just cannot stand those LOUD anoying exhausts. I am VERY happy with the Apexi World Sport 2 Catback. The cat back looks great on my Integra LS 4 doors. Anyone needing the cat back for their LS will have to purchase the 4 door GSR exhaust and the muffler shop will have to slightly modify one of the pipes, no biggy. This exhaust is very quite at idle and also at wide open throttle. I HIGHLY recommend it. I purchased the same cat back for my cousin who has a VTEC integra. Let me tell when VTEC kicks in it is amazing on how quite the exhaust remains but yet you don't lose the power.

low to mid range power gains nice look and fit good backpressure

hangs a bit low would definatly scrape if lowered NO real exhaust note sounds like stock!!

I just installed my apex ws exhaust system today and was surprised with the mid range power gains. I was also surprised that i lost little to no low end power. Yet I was disappointed with the exhaust note or lack there of. If you're looking for total stealth this is the exhaust for you, but if you're like me and wanted an exhaust with a little sound this definatly ain't it. Score of 1-10 this gets a 4!
