Hey guys im buying a header but i cannot decide between PLM, skunk2 and Berk. My current mods are HKS Hi power single, 70mm test pipe, takeda intake, and flashpro. Which header would i make the most power off of once im tuned? I was leaning towards the berk since it has 50mm primaries and secondaries but someone told me i should get a smaller size header for better back pressure since i already have the test pipe. Thanks in advance.

 

have you looked into Ballade?

 

Requiring back pressure is a myth.

Stock is VERY good, but the Urge Unicorn header is one of the best on the market.

Other popular choices are J's Racing, and PLM is just a replica of the J's, but at a much cheaper price.

I'd advise against any sequential headers, (Ballade, Skunk 2) as I have heard you can lean out certain cylinders unknowingly due to the firing order.

With that said, there are minimal gains in the header department, you could spend your money on other things that would make a bigger / more noticeable difference such as lightweight flywheel, wheels, get an AFR or oil pressure gauge for monitoring things (I won't mod another car without a wideband, personally) or get tuned if you aren't already.

 

Save your money and just buy the PLM.

 

More like save your money and leave the stock one on. Your tune and test pipe are going to give you all your gains. Like Liquid said spend the money elsewhere since you will see larger returns.
