Flashark

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.

Unlike the picture, the muffler goes between the new pipe and the old tailpipe,or in the back of the new pipe.

With the 4" exhaust with muffler, the noise is significantly louder than stock. I was hoping for quiet, but that is not the case. You can hear the extra sound of the exhaust going down the highway.

Made my gt look great gave it the stance I was looking for a little bouncy but think I need to adjust the damper but they ride great definitely worth the price

71 c10, using original big block mounts with plates keeping everything in factory location. No frame clearance issues on top or bottom rail, plenty of room. Both sides drop in from the top, all bolt holes lined up. Only thing tight is around #3 plug, used a shorter regular socket with wobble extension instead of spark plug socket to tighten plug. I trimmed stock style boots, some smaller angled ones would really be ideal. Overall very pleased with the quality, fitment, and price. Have several eras of Chevy trucks and will definitely be using again.
