As the title says, I am confused about the options for a good exhaust manifold.

Obviously the quality of the $1200 Jun one will be better quality than that of the Megan Racing one. But I'm not trying to build a show car..

My question is: on the stock turbo, is there really any difference in quality/performance gain in the exhaust manifolds <$500?

The same goes with reasonably priced 02 housings...

Thanks.

 

No. There is minimal difference between the cheap manifolds in performance or quality from what I have seen/heard.

Until you spend a lot of money 700-1000 dollars all the stock turbo manfolds are basically the same.

the o2 housings are all the same... sometimes on ebay youll get a junk one with bad welds, kinda luck of the draw...


as far as manifolds go the gains are all pretty close.. a manifold liek borla has long runners and offers a little more top end with a slight sacrifice in spool...

a ported stock manifold will gain a little torque and horsepower...

megan will lose a little torque gain a little power....
