Fk8 coolant reservoir

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

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.

Great Shorty Headers

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

So far, so good!

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 for the 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.

Great product & bargain

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!

Small block headers

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.

Install was easy.

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.

Fit great, will def buy again

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.

Top Shelf greatness

Received mine with the box a little damaged (purple company fault) BUT my pipe was packaged great and just like other reviews said it was in perfect condition. They packaged it great (i wasn't even worried) with no scrapes or damages at all. The flanges are beefy and thicc (no diddy) and again the welds look race durable with excellent quality. My build is coming along nicely. Top shelf quality with well tap pricing lol.

go place to get parts

good place

they are fast on there shipping good part for the money i will buy more from them thank you

Great product and company

Company went above and beyond to make sure my exhaust fit the way it should. One of the best experiences I’ve had working with a company

Upper Control Arms

I received my upper control arms yesterday and couldn’t be more impressed with them. I only bought them because of the great price and wasn’t expecting much, but when I opened them up and saw the size, quality and construction of them it blew me away. Super high quality and strength. Amazing product and would highly recommend them to everyone looking to upgrade their upper control arms.

Hi, thanks for the review and pictures, looking forward to your next purchase!

Best car parts company to date…

I’d like to start off with how fast the shipping is, within a few days my new headers and down pipe arrived. After bolting everything down sadly I missed the nut that goes over an empty valve hole, and it fell off driving. I reached out to flashark and only asked for a replacement nut, not only did they respond within the hour I had sent the email, not only did they replace the nut, I got the whole new set of headers and downpipe. Amazing service, amazing products as well (I love the headers). Definitely buying again from here.

Hi, thanks for the review and pictures! This is what we should do. We apologize for the inconvenience. We'll continue to improve our service! Looking forward to your next purchase, we will give you a discount!
