OBX or Megan? I don't think either of them are the highest of qualities but they're affordable and if I was to choose one, which would it be?

OBX 4-2-1, 1 piece
Megan 4-1, 2 piece with resonator

Help me out guys! Thanks

 

A 4-2-1 style header will show a boost in torque (which is greatly needed on a 1.6L inline 4) while a 4-1 will show the best high RPM gain. Street car? Gor for the 4-2-1, or in muscle car terminology, tri-y headers. A 4-2-1 has a better pulse back at the exhaust valves at lower rpm due to the step in piping.

 

hmm interesting. learned something new today. thanks!

 

Theres lots of science when it comes to header design, best to read up on it and then go from there....a quick google search turned up a few links on header basics...

Welcome to NAM!!!......"Once you mod, you can't stop!!!"

 

What gain does a non-S truly realize from the addition of a header?

 

Alright cool stuff. quite educational. Thanks!

Im leaning towards the 4-2-1

 

It helps when you have a technology/science/engineering teacher freak for a class about engine repair.

 

megan didnt increase power at all with the stock cat, without it my car is rich and I am actually loosing power.

 

I see.. does anybody know anyone whos had the OBX header installed on their MC?

 

I'm pretty sure there is a HUGE thread a while back on the obx and who has it. I have heard nothing but good things from the obx minus a couple of fitment issues.

 

ah yea found a couple threads. thanks

Im now leaning even more towards the OBX.
