Girlfriend was very happy with the early gift

Not nearly as loud as I thought it would be but for her it was perfect, not nearly as loud as it is in the video maybe that’s cat less but overall not the worst item to install and it sounds good and looks decent

These headers fit great in my 65 buick gran sport with a 6.0L LS/TKX 5 speed. I have a hydraulic clutch however the look like they would also work with the factory Z-bar linkage. My engine is hammered as far back and as low as I could get it in the chassis, hardly any header bashing was required to get them to fit. Great product especially for the price

Fantastic Quality and Value

Fantastic fit and finish. A third the price of the "name brands" and does exactly the same thing. Even includes a check valve built into the outlet hose.

Fantastic quality. Why pay more?

This tank fits my FK8 Type R perfectly! Excellent fit and finish and easy to install. Why pay 3 times as much for something else with a more recognizable "name" stamped on it? No need - get this one!

Okay for the price

Left side header has quite a few scratches in it. For the price I really can’t complain but if you want perfection this isn’t for you

Exhaust Headers For 1988-2000 Honda Civic / Crx / Del Sol SOHC D16 (D16A6/D16Z6/D16Y8)

Fit 2000 Civic LX

Removed old cat/manifold and installed with aftermarket cat from eBay. No it isn’t meant for an LX but it does fit. I also ran over a deer that someone else had hit, of course, the day after I installled it and it is all still in place and rock solid. Would buy again and recommend to others. Has been on for a few weeks.

Long Tube Exhaust Headers for 1997-2004 C5 Chevy Corvette LS1/LS6 5.7L

My C5 Flashark Headers Experience

At first no one wanted to install them because they wasn’t the high class name brand and because of the fittment. I found a shop (Johnny’s Garage) and he was up for the challenge. He pointed out a lot of flaws and by him being a welder he was able to do some modifications and fabrication. Curtain things didn’t align up such as the gaskets, the fitting of the headers that was too close to the undercarriage of the car and where the headers bolt on to the oem braket. Other than that he made it work and I was happy with the 3 day project waiting on parts… smh. I spent more than I was supposed too :( on this project because he was the only shop that wanted to take on this project. My car sounds amazing tho🫡 Thanks Flashark for your affordable price compared too others.

Exhaust Header for 2001-2005 Lexus IS300 3.0L 2JX-GE DOHC ALTEZZA XE10 JCE10 l6 2JZ-GE

Pleasantly surprised with this header

I ordered this header as a temporary replacement for a cracked "name brand" header. I'll be completely honest, due to the price I was not expecting anything great but I was surprised, it's actually pretty good.

I did have a hard time fitting the header. The two banks weren't spaced far enough apart so I did have to use a big pry bar and hammer to get bank 1 into the studs. After this, I was able to zip the bolts into the studs with no issues. The header did seem just a touch shorter than the "name brand" header I had before. Neither of these things were an issue for me, for the price it's about as great as I could have expected. Build quality seems on par with the other header I had and the O2 sensor locations are actually better (perfect IMO) on the flashshark header.
I don't expect the included gaskets to hold up forever, if I am able I will update this review next drift season.

I did wrap the header with DEI titanium heat wrap, the "polished" finish looked great before wrapping.

All In all, I bought this header for temporary use, but I'll be using it permanently because it seems like it's going to be completely fine, in fact better than a "name brand" header.

You will most likely struggle a little bit during install but for the price (which is REALLY GOOD) it is completely worth it.

I would recommend this header to a friend and I would buy another!

Catback Exhaust System For 2015-2020 Ford F150 2.7L 3.5L 5.0L 3-Inch W/ Black/Polished Muffler Tips

Richard P.

Great product for a great price.

Looking for a dual exhaust setup for my 19 F150 5.0. Researched all the HIGH dollar systems and none had the sound or look I wanted. Stumbled on a video and there it was. The dual exhaust that had the look and sound I wanted. And best of all it was 1/3 the price of the others.
A bit skeptical when all I could find was 3 reviews and videos, but took the chance. It arrived in less then a week and when I opened, I was surprised at the quality, but still skeptical about fit.
Unboxed and laid everything out and started the install. The only thing I didn't see was instructions, but being a typical dude, I don't read instructions anyway. Got it all in loosely then started tightening and adjusting. Snugged everything up and took a quick ride, came back and made sure all stayed tight and in place and was done. All said and done taking my time, took about 3 hours start to finish.
Definitely don't regret this purchase, looks and sounds great and so far no drone at any rpm.

Great kit

Installed was easy and quick. Great product and well under the price of some catch cans going for ridiculous prices! Thanks for giving us an alternative.

good product

Put this on my MK5 GTI and the turbo spools faster now. The deeper tone is addictive, and the install was straightforward with basic tools.

Works Exactly as Intended

Put this catch can on my ’21 Q60. Install was straightforward, hoses lined up perfectly. Engine feels smoother on acceleration, and I’m confident it’s preventing future carbon buildup.

Great Fit and Sound

Put these on my ’10 G37 Coupe last month. Fitment was spot-on, install went smooth, and no rattles or leaks after a few hundred miles. Noticeable bump in power and a deeper exhaust tone without too much drone.

Installed these on my ’08 G37X over the weekend, and I’m impressed. The fitment was spot-on, no weird gaps or alignment issues. Throttle response feels snappier, and there’s a nice bump in low-end torque. The sound is a bit more aggressive but still daily-driver friendly.

I installed these on my 2012 G37 Coupe. Fitment was decent—took some effort around the steering shaft but nothing crazy. Once installed, the car feels more responsive and definitely pulls harder above 4K RPM. The sound is throatier too, especially at wide open throttle. Paired with a tune, it made a noticeable difference. So far, no leaks or issues.
