please share your experience, are they reliable ?

 

Pos....cracks and fitment is so so.....spend more $$$ for a tubular manifold or just port the stocker......$.02

 

I have one and like he said cracked in 3 places. I had my buddy redo most welds and put some gussets in. there nice but they dont put enough fill on the welds. no their O2 housing are great dont know where they went wrong

 

Just do a stock ported manifold and it will be better. I have seen cars lose power from those manifolds they are ****.

 

what is done when porting stock manifold, just gasket matching it or are the runners enlarged as well ?

is there any DIY for it ?

 

Don't buy one. i regret getting one. It cracked in less than a year, got it welded and it cracked again. Now I'm using my ported stock mani. The Megan manifold is a great paper weight tho imo...

 

what about XS power, same junk as megan ?

 

That looks like it's about to crack...

Are those mani (like megan) is cheaper than ported stock mani?

 

i remember people saying that full race and shearer manifolds are good. but full race is about a grand. $$$

 

Toxicfab manifolds are ridiculous! and less than a grand... that would be my direction personally.

 

Stock ported by MAP

 

Toxicfab manifolds aren't any better than the map long runner or the fullrace manifolds, I have had both the quality is the same, I prefer the the map lr because of the ss flanges and semi polished finish for $825 best value for a top quality manifold imo, plus curt brown uses it and if it doesn't make power he won't run it.

 

Let the pic do the talking!

save money and time , just get a stock mani and get it ported. you will not regreted.

 

Just like everyone else will tell you, Megan or any of those eBay brand manifolds will crack. They seem to have the same runner design too just not all the same name.

I've read some people don't even bother with a high end manifold until you are 500hp+

Having your stock one ported and coated isn't too bad or you can find a polished heatshield to cover the... rugged look.
