Best out there for the price and well-made coolant reservoir right now.

Check out my install video for details on this.

Installed these on my 2003 Civic, and the improvement in handling is incredible. The car feels more planted, and the ride is still comfortable. Great product

brightly colored, easy installation and nice ride, using for several months no complaints

I’ve been using it for the past 2 weeks and it has definitely added some horsepower to my car. It also sounds good paired with my red exhaust 👍🏼

Bought is not knowing if it was going to work on my 535i. It wasn’t a direct plug and play but nothing my fab guy couldn’t fix. Made a custom fitting to make it fit, adjusted the axle back on some places to fix some fitment issues but nothing major. Came out great, and sounds awesome.

Never heard of flashark. I read about them and found the parts for my 2500HD duramax. Price was right and the parts fit. Thank you flashark!! I told some friends about you as well!

I really didn’t need it but at this price I couldn’t resist it and it’s very similar to the other brands.

Perfect for my Ford f150 1979 4x4 351 M

They look great for the project I am working on. 48 ford f1 custom built with a SBC 350.

Installed on my LS 5.3 for my 1960 C10 build, quality looks good, fitment was good still along way from starting, but overall happy with the purchase.

My old headers developed a giant stress crack so I needed something in a pinch. These were great. The hardware was wrong, but i reused the old stuff. Not a big deal. These are really well made and quiet. Some headers have a ticking not these. Very strong-walled and sturdy.
Just an FYI 89 351w bolts are 3/8

Had my doubts. They’re pretty inexpensive. But I got tired of replacing cracked exhaust manifolds, do I thought I’d give Flashark a try.
Installed them, and they fit almost perfectly! I don’t really notice any difference at all except they’re quiter than a cracked exhaust manifold.
Then again, my truck is a 382,000 mile beater, so I don’t think I would see any sort of gains anyway!
Thank you Flashark for offering these headers at a very reasonable price.

Great product, also fits the 3sfe, overall it was great for the price and fit something it wasn’t necessarily supposed to so i’m quite pleased. Made my 1989 celica sound a lot better as well.

Fitment is great, it is a difficult task but once finished very satisfying feeling. I used the whole kit for my 03 sequoia, no issues. Loving my 4.7 more & more. Thanks flashark!

I've had these headers on my truck for a little over a month now and I have to say that these are the best shortie headers for the price. You do have to bend the factory y-pipe but other than that it's a straight bolt on. I do recommend that you make a custom y-pipe though, I just bolted my new one up and it sounds even better with a little bit more power too.
