Headers Question

True but doesn't PTUNING allow you to retain your headers? Not trying to be a smart ass or anything but that's the only one at the top of my head I can think of. They're pretty damn expensive though lol

That's correct. I think the WORKS turbo kits also allow you to retain your header.

Well there's 2 options for the OP to look at, if he/she ever wants to go turbo route lol. But hey there also supercharger options as well(;

HAHA good point! Ptuning I would look at but not the WORKS kit.

So as not to derail this thread too much:

I picked a UEL header because the rumble makes me happy. I'm not building a race car, so I don't care that EL headers produce more power in the high revs. OP, you should listen to video clips of various exhausts and see what sound you like best.

I like the Open flash and Borla UEL sounds. JDL is too but just find it too pricey. I know the quality is way better, but like I said, I`m not looking to make the max power, I`m not trying to out accelerate another car to make a pass in T6. I want to make the car sound good to my ears and just free up some power at the same time.

It's not EL vs UEL for where the power is made, it's 4-1 vs 4-2-1. A 4-2-1 header will have better midrange gains, while a 4-1 will have better top end gains. That all assumes it's probably designed, and not just cobbled together with no thought to runner diameter, steps and runner length.

Personally I want no part of a header that is designed to give unequal backpressure, scavenging and heat to half the engine vs the other.

All of the well designed EL headers (ACE for instance, or P&L, JDL, HKS, etc) that I've seen on here with custom tunes fix the torque dip. Also regarless of UEL vs EL, both designs show modest gains in the upper RPM range - certainly there, but nothing earth shattering for either configuration.

When it comes to 'lesser' (cheaper) headers, you'll see variance all over the place. I've seen cheap UEL and EL headers both fail to fix the torque dip. I've also seen poorly tuned 'good' headers fail to fix the torque dip.

In the end, just save your money and get a turbo kit that includes a header

Would Tomei EL or UEL be considered good?

Tomei is a solid brand. Can't go wrong with them. Keep in mind the tubbing walls are thin.

Honestly I'm not sure - it's a complicated thing, as a good tune for that specific header is important. Just look at the recent thread where the guy gutted the cat on his stock header and re-tuned. What makes a good header is way over my head - I just rely on aggregate dyno results of people who have tested various headers. The Tomei headers certainly look nice, maybe in the same league as the openflash headers, but I haven't seen any dyno results (with good custom tunes) to compare.

You got to look at your end game.

Pick a sound
UEL - boxer rumble
EL - normal 4 cylinder sound

UEL - generally better gains in low/midrange, sacrifices a few hp top end
EL - not so good low/midrange but few more HP top end

Tomei, JDL, openflash Gruppe-s ect are your average priced headers

and plenty of flash & go or canned tunes available from ecutek and OFT guys for these


Then you have P-tuning and Nameless and ACE the higher priced headers


ACE header is probably the pick of the bunch as it combines benefits power/torque) of the normal EL/UEL header (it an EL header so no boxer rumble though). The ACE produces good gains entire rpm range.

Rub is its expensive and you will need a custom tune to get the max benefit as I dont think anyone is offering flash & go or canned tunes for ace header (or P-tuning or nameless)


If your just street driving and staying NA then probably just get a UEL header and a flash and go or off the shelf tune from ecutek or OFT guys

If you going turbo then most kits will require you to run a different exhaust manifold (header) to connect up to turbo, some can use original header but very few.

supercharger kits you can use your original header. , nameless might be an issue for some kits due to its design.

I'm still learning about my car and I'm not sure what I'm looking to purchase next, so if headers seem more beneficial than a test pipe, I'm all in. Thank you in advance to all who help.

Personally I prefer the EL sound.
Both types will help increase power, but it's really the tune that makes the biggest difference. I wouldn't expect big gains with only an exhaust. Don't be fooled into thinking otherwise.

Like some of the dudes say - consider future plans too... Turbo? Then don't do a header now. SC, then sure. NA, then sure.

Have fun and post pics of what you do in the end?!

Nameless .. if you think of Cossworth's as Nameless (there are some changes though), then it has canned Cossworth's tune.

This answered every question i still had remaining regarding headers haha
