2006 Ram Megacab Headers

Amazing service and amazing headers such good quality and the the support is fast and extremely helpful definitely deserves 5 stars

Nice system 2006 Silverado

Fit is decent, needs a little modification nothing major, would recommend using butt joint connectors instead of u clamps, as some of the connections aren't quite tight enough but overall real happy with them!

We apreciate your photo feedback and review! Thank you for your support!

Great fit, after two cracked cast manifolds this was a nice upgrade.

Does it's Job

This fit perfectly and went in with no problem. I did have to get three bolts to connect to the existing rear tail pipe as the pressure fit bolts where connected to the DPF. Some models appear to be connected to the rear tail pipe flange. No biggie, happy with how it turned out! I got the model with a muffler as I wanted to minimize the noise.

63 Falcon Sprint upgrade

This was a perfect upgrade for my 1963 Ford Falcon that I’ve owned for 53 years. It functions and looks GREAT! Thank you

Gorgeous car!!


I was hesitant to purchase such an inexpensive delete kit mostly because of internet reviews of other cheaper priced kits and fitment issues associated with them. Well, I had no issues at all with this kit fitting my Duramax LLY. The only modification I made was to use a gasket on the intake side instead of the supplied O-ring. This is a great product at a great price.


Excellent quality, fits perfect and got it way sooner than I expected. Finishing everything up now extremely please my LMM needed it BAD!

6.6 Duramax delete kit

The product worked great, They were out of stock in my color and couldn't 2 day mail it to me so that refunded my shipping cost.. They were very easy to work with very good customer service

Cummins EGR delete

Kit worked great, everything lined up just as it should and no leaks. Only problem i had was the countersunk hex key bolts for the EGR valve didn't fit into the block off plate, just had to grind them down a bit to get them to sit down inside the plate. I would recommend this to anyone though. For the price you cant beat it! And super fast shipping!

Very good

Thank you for your message. I'm glad you have such a comment. I hope you can come again.


No instructions were in the box. Made install a little tricky

Nice for price

For the price, it's okay. I do recommend it.

Egr delete

The egr delete fit nice. Had a problem with the hose and clamp would leak. Ended up replacing hose and clamps. But nice kit.

Ordered for LLY but dose not fit 2006 LLY haven't had time to return and get correct kit shipping was pretty quick for the original order

Hi, if you want to exchange the wrong kit, please contact service@flasharkracing.com

Spacers exactly what I was looking for.

Only negative I have to say is I wish the studs were a 1/2inch shorter or a side note that you need deeper lug nuts. Other than that they are great.


Fit Great easy to install Great product!

Easy installation

Took a minute to get but was easy to install will need a hose clamp didn't come with one. So far so good

Great downpipe

Great price, good quality, fast shipping. Can't ask for more.

Great product, fast shipping

Great Improvement!!!

This is one of the best things I’ve done for my 6.7 Cummins! I got about a 15-20% increase in fuel mileage and my engine runs about 15 degrees cooler. The parts are quality and look good but the instructions weren’t all that great. I had to watch a YouTube video on how to install this kit. Be aware that you will get an engine light after you are done. As far as I know you have to buy a delete tuner to clear the light or just put black tape over it like I did! Lol! Overall it is a great product and a nice improvement to my pickup and I would recommend to anyone.
