Frequently Asked Questions: FLASHARK 2016-2021 Honda Civic 1.5L Turbo Catback Exhaust
Q1: What is the best aftermarket exhaust system to buy for a Honda Civic 1.5T?
A1: If you want the perfect balance of power, deep sound, and affordability, the FLASHARK Honda Civic catback exhaust 2016-2021 1.5L Turbo w/ N1 Tip is a top contender. Unlike cheap slip-on mufflers, our full T-304 stainless steel system features mandrel-bent piping to eliminate backpressure, giving you proven 10-15 HP gains and a refined, aggressive tone without the annoying highway drone.
Q2: Will this fit my specific car? I have a 2017 Honda Civic EX Sedan.
A2: Yes! This Honda Civic sedan exhaust is specifically designed as a direct bolt-on for the 2016-2021 Honda Civic 1.5T Sedan models, including the EX, EX-L, and Touring trims. Whether you need a 2016 Civic exhaust or a 2021 Honda Civic exhaust, if it's a 1.5L Turbo Sedan, this is an exact fit.
Q3: Will this fit a 2016 Honda Civic 2.0 exhaust system or the Hatchback models?
A3: No. This specific Honda Civic full exhaust system is engineered exclusively for the 1.5L Turbo Sedan. It will not properly route under the 2.0L naturally aspirated engines (like the LX or Sport 2.0L) or fit the Honda Civic hatchback exhaust system due to different chassis lengths and bumper layouts.
Q4: How does this sound compared to a Honda Civic straight pipe?
A4: A Honda Civic straight pipe on a 1.5L Turbo often sounds raspy, overly loud, and creates terrible cabin drone. Our catback exhaust Honda Civic setup uses a tuned N1 Style Muffler to filter out harsh high frequencies. You get a deep, mature, and aggressive growl when you step on the gas, but it remains smooth and manageable during daily commuting.
Q5: What is the average cost to install a cat-back exhaust on a Honda Civic?
A5: The cost to install cat-back exhaust on Honda Civic at a professional shop usually ranges from $150 to $300, depending on your location. However, our Flashark exhaust features a 100% direct bolt-on design with no welding or cutting required. Many of our customers with basic garage tools save that money and install it themselves in about 1-2 hours.
Q6: Should I just buy a 2017 Honda Civic muffler or upgrade to this full catback system?
A6: Upgrading just a 2017 Honda Civic muffler will only change the sound slightly, but it leaves the restrictive factory mid-pipe in place. By installing a true aftermarket cat back exhaust system, you are replacing the piping from the catalytic converter all the way back. This is required if you actually want the 10-15 horsepower increase, better fuel efficiency, and improved throttle response.
Q7: Will this Honda Civic cat back exhaust system improve my gas mileage?
A7: Yes! By removing restrictive factory bends, this exhaust system for Honda Civic allows the engine to expel exhaust gases more efficiently. Under normal driving conditions, many drivers report a 5-10% improvement in fuel efficiency. More power and better MPG!
Q8: Does this kit include everything I need for installation?
A8: Absolutely. As one of the premier Honda Civic exhaust kits on the market, your package includes the high-quality stainless steel piping, the N1 muffler, and all necessary TIG-welded CNC machine flanges and hardware needed for a leak-free installation.

A10: Definitely! If you are searching "can you show me a photo of them," simply scroll up to our product image gallery. We have detailed undercarriage shots, installation effects, and close-ups of the beautiful 3.8" N1 tip perfectly filling the rear bumper cutout.
Q11: Will this 2016-2021 Honda Civic catback exhaust cause a Check Engine Light (CEL)?
A11: No. Because this is a cat back exhaust civic upgrade, it installs *after* your factory catalytic converters and oxygen sensors. It will not mess with your vehicle's emissions readings or cause any dashboard warning lights.
