I've had this header for a while, and I've always wondered if it was bad. The two center pipes are much longer then the side ones. Would that result in poor performance?

 

any dyno numbers? who made it?

 

No dyno numbers. It's a generic eBay header ($90 shipped)

 

use all that money you saved to dyno it

 

Well, I do plan to go to the dyno in a few weeks, but I'd like to get the highest reading I can when I go there. I'm mostly asking if anyone knows if having short primaries on 2 cylinders and long ones on the other 2 will be bad for performance. Usually when I look at a header, they're all about the same

 

i doubt that the ebay header company researched exhaust pulse / runner length .. but you may never know?

 

put it on the dyno and find out.
