The exhaust manifold is the first component of your vehicle’s exhaust system, bolted directly to the engine block. It collects exhaust gases from the engine and expels them through the exhaust pipe. By upgrading to Flashark exhaust manifold, you’ll experience enhanced engine performance, including increased horsepower, torque, and improved throttle response. The optimized exhaust flow also reduces engine load, leading to better fuel efficiency, while the more aggressive exhaust note adds a sporty touch to your driving experience.

It’s important to note that the Exhaust Header is a performance upgrade to the Exhaust Manifold. While the exhaust manifold channels exhaust gases from the engine into a single pipe, an exhaust header offers improved performance by using separate pipes for each cylinder. This design reduces backpressure and improves exhaust flow, resulting in better horsepower and torque, especially for high-performance applications.

2017-2021 Honda Civic Type R Aluminum Coolant Reservoir (Degas)

Civic type R Coolant tank

Works perfectly for the FL5. I just needed something that wouldn't crack under pressure on track. It has very good construction and all of the points and hoses line up. I took it straight to the track and it held up fine. And it's priced way under the premier name brand tanks. No need to spend $3-400 on one. 5/5 would recommend.

1991-2001 Nissan 200Sx / Sentra / NX Infiniti G20 2.0L Exhaust Header

Nizam M.

2001 nissan sentra SR20DE

Firstly let me say that I was very skeptical of ordering from this company.. Every one I asked said they have never heard of Flashshark.. But I took a chance and it paid off.. The product was well made ,came with all the required hardware. I only had but 1 minor problem with one of the holes on the header not lining up but a drill fixed that in a minute.. The product was delivered in a timely manner and I was updated on every step of the way.. So if you're a skeptic like me ,don't be .Give Flashshark a try..

High Flow 3-Inch Downpipe Exhaust for 1999-2006 Audi S3 & TT 1.8T Turbo

GEORGE D.

2004 Volkswagen beetle with Audi TT 225 drive train

I would like to get the best review I can, but I don't think mine will apply to most.
The product looks great. I have a 2004 Volkswagen beetle that has a complete running gear out from underneath an Audi TT. So this product didn't fit perfectly, but was very little modification it fit fine. Save me a lot of hassle from having to make it my self.

05 tc headers

Arrived several days early, great quality. Didn't come with the bottom gasket which was ok since mine old one was good, and threads were wrong. easy install. Sounds amazing. I would recommend a good muffler, it is a little raspy

Header and cross pipe 1997 Jeep Wangler 2.5

This header was almost perfect had to drill the first foward hole out a little larger to fit the bolt other than that it bolted on with easy. Use a long extension for the fifth bolt from the front. The cross pipe lined up beautifully. From start to finish was 3 hours.

Thank you for the attention to detail.

Exhaust Up-Pipe for 2003-2014 Subaru Impreza 2005-2009 Subaru Legacy 2.0L

Exactly as pictured

Comes with new nuts and gasket. Bolts right up. 0 fitment issues. I heat wrapped mine. I suggest you do the same.

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.
