Which headers are the best?
 

Hey guys, I am new the car scene and I just wanted to know which headers are best for performance for our cars? Which give the more hp gains? and would i have to buy the same diameter piping as my aftermarket exhaust? i have a tsudo exhaust. I want to buy some with my next paycheck with the hopes it will give me a little more hp and with the hope my car will sound better

Exhaust section, lots dynos and discussion and opinions there.

No such a thing as the Best parts .. especially when you're going to be adding more than one since nobody has done the infinite (nearly) combinations of all the various parts + tune each set up
I personally am looking forward to what seems like a whole years of R&D from nameless made for us in terms of header .. it looks interesting :)

There haven't been many before and after dynos showing gain from header alone. I had a friend get his car tuned with TRD intake and stock exhaust and then swapped in a JDL header over pipe and catted front pipe and retuned at iirc +27 whp at peak. I have retuned his car since and picked up a few more. I have yet to see more "proven gains" as most are stock vs header + tune.

@Rev Works .....what else is there to say

I loved my Revworks header when I had it. I also used to have the Tsudo exhaust as well.

@jaime3, Moved to Engine/Exhaust section.

For the most power I'd look at the new JDL EL v2 HKS and Nameless... They are all over 1k.

For cheaper power I'd look at PPE Revworks and OFH

I'm been looking at headers a lot lately and it really depends how much you want to spend and what you are looking for. With a tune + header combo the JDLs are great and expecting the Nameless to be above them performance wise. If you are going to try and stay on stock tune there are only so many options that will net you any gains while not throwing cels. I have narrowed my list to JDL, Nameless, and the OFT combo (tablet + header) for what I'm looking for I'll have to get a tune with my header and the OFT combo seems like the best bang for the buck considering the combo costs as much as just the header from JDL or Nameless

The Borla UEL headers have been the most popular for us in terms of quantity of orders for that part number, and so far I haven't heard any complaints, it's all good news from my customers on that, so I'd probably go for that one.

We've got another install for one I think tomorrow, or the following day, so we should have videos coming shortly after that.

It depends on what you are looking for. From the dynos i have seen the UEL headers with a tune flatten the torque dip out and give a bit of a boost through out the range.

The EL headers are a bit different in that they can be tuned to give a boost at different rpms. Ones like the FA20Club and P&L with a tune actually give you a torque bump where the dip normally is but up top are similar to the UELs. The JDL and SuperSprint ELs seem to give you more of a boost up the top end but you'll still have a torque dip (altho a reduced one) in the low to mid range.

What ever you choose you really need a tune to make the most of the headers.

whats the differrence between equal and unequal?

If you aren't planning on going FI, then the difference between EL and UEL are very minimal. Just choose which you think sounds better! The best EL headers are definitely Nameless, once they come out with it. Both the UEL and EL from JDL are great and their headers show some really good power gains. If you are on a budget and want some headers OFH are not a bad choice either.

No difference between el and uel if staying NA?

Put down the crack pipe.

Uel is for sound. It's a compromise. It might give gains, but a well calculated EL header is always better.

If you're buying headers based on sound, you should probably just play a cd through your stereo of race engines.
