Welds aren't too bad, fitment is pretty close (mine hangs a little lower off the back bumper than I expected). Gaskets that came with the exhaust didn't look too impressive but I hit them with some copper gasket spray and threw them on anyway. Got a nice throaty tone because of the rest of my setup. Notice a couple flanges were slightly warped so I hit them with a belt sander to flatten them out again and don't have any leaks at all. Good product for the money overall.

Very easy to install with just a couple hours of labor under the car. I've never performed exhaust/muffler work but found this product very easy to work with. The kit included everything one needs to do the job. Although it might be worth it to purchase an extra one or two rubber hangars in case you need to cut one of the old ones off (for ease of installation). The sound of this was a pleasant low pitch that is not overbearing when in the vehicle. I would highly recommend this for anyone who needs to replace the OEM parts.

I purchased this item and took six (6) months for me to install due to life's issues. The muffler had some of the insides come loose after five (5) months use and sounds like trash when I drive. Contacted the company and they said I had 30 days to return it and a 90 day warranty. If the warranty is this bad, the product is also. I would NOT recommend purchasing this muffler, as you will be replacing it within a year like I did!

I have had this on my Integra since November. Car had some issues so it sat majority of winter. And have engine issues as well so it could partly be to blame. I love the sound, has the deeper tone that actually sounds like it should. Not that wine you hear with "fart cans" what I call when the just slap the end piece on and not a catback! It fit really well, had it installed by a mechanic. Rattles a lot in the middle section, don't know if this is common but I also have engine issues so it could be the reason. Haven't tried the silence yet although I was pulled over by a Michigan state cop, said it was loud but never said it was a warning so I left it alone. It does get very loud during higher RPM but sounds great, especially in tunnels or close proximity walls. Being I am in Michigan with winter it did loose the chrome finish pretty quickly with winter. Overall good price, if you could would go for better quality. Bought this cheap because just needed an exhaust for the car.

I purchased the catback to replace my old rusted OEM exhaust that had exhaust leak. The installation is pretty straight forward. Make sure to align up the three bolt flange. If the bolts don't align properly then rotate it to make it fit. Also I had issues with vibration sound like metal to metal contact. I found that the hanger on the muffler section was leaning on the muffler hanger on the vehicle. Spec-D need to revisit the hanger location/design on the muffler section. I just cut my hanger off on my muffler section and no metal to metal contact vibration sound. The exhaust doesn't sound bad with silencer like some of these fart cans. Overall, the product is not bad. I wouldn't put this on my toy Integra. But thumbs up for daily driver LS auto with exhaust rehab needed.

Great! Great! Great!Sounds great- no cat, 421 header, large glasspack resonator where cat should be = no drone, can talk in the car but at WOT it roars, not farts, and at idle, it's so low of a tone it sounds like more displacement than my Supra... I'm very pleased. Build Great! The can is a little cheaper looking with seams and the resonator really could be backed up with another glasspack as I did (responsible volume, less drone in car, better tone) but otherwise it's flawless. Grade 8 bolts and graphte gaskets included. Not a scratch, arrived by deadline in DNA box.10/10 recommend if you're not gonna spend $600+ on an HKS or GREDDY lol

Bolted on as it should. I Put the car on jackstands and had this catback, a Magnaflow Direct Fit high Flow Catalytic Converter & a Spec D header installed in under 2hrs with basic hand tools. -1998 Integra LSCar has a nice Deep rumble from idle up to ~4500RPM and than it sounds like your typical all Motor B18 (silencer removed, sounds worse with it in IMO)

I’ve had this catback exhaust on for about a year. Not bad for the price. I hate how the silencer looks but it’s ridiculously loud without it, it’s impossible to have a conversion in the car without the silencer. Fitment could be a lot better, can slightly tilts down towards the back and a part of the can touches the bottom of my bumper so it’ll probably melt it away eventually, black drip on the can is melted bumper in the picture. I live in So Cal So rust isn’t an issue but parts of the can is starting to get tarnished as seen in the outer lining of the can in the picture. I have 4.5 inch tips on my other cars so this tip is a little small for my taste. When it comes down to it exhaust systems really don’t give you very much power gains unless you’re turbo or have a European car, it’s more for looks and this exhaust definitely doesn’t give you much gains but then again neither would a $500-$800 exhaust system. I would probably not buy again since I personally don’t like the way it looks, with the slight can tilt and tip size but then for the price I really can’t complain too much.

Fit great on a 01 GSR. The resonator has to be flipped when installing. Sounds good for the price as well.

Installed on a 95 integra lowered 2.5inches and the exhaust is almost touching the ground, be prepared to scrape very often!

Fits alright. Had to flip the resonator the first flange was upside down. Hangs a bit lower than the stock exhaust so scrapes sometimes. But for the price it's a pretty good system.
