XForce E/L headers Experiences
People, I need advice or some experience from those who have fitted xforce E/L headers to their cars, [B]I am considering this only on the advice that you don't loose the boxer noise with the headers mentioned above[/B], but I don't understand as everything I have ever heard is that e/l headers kill the boxer noise. I have had an XForce TBE fitted on the car for 2 years now and am very happy with it, so quality is not in question, I just don't want to spend coin on something that may rob me of that which I love, Boxer joy!
Cheers. |
To keep the boxer rumble you need unequal length. They give you more low end torque too. Buying a subi I love the noise, so I wanted to keep it. Sacrificing something like the boxer rumble for a bit more top end HP wasn't worth it IMO

Ask Slap Dash, I think he has them on his car.
Yes, you will lose the rumble but you will also get a few more horses. It is a personal preference really. I am definitely getting them next. using the Perth-WRX mobile app |
Equal length for power/efficiency, unequal length for rumble.
Personally I don't mind either for sound, but if you love the boxer rumble, keep unequal length headers. using the Perth-WRX mobile app |
I have equal length and still have rumble at idle...
|
Alike to Astralex I still have a Boxer rumble (Not as loud & obnoxious as Unequal tho.) Xforce's new design apparently is rated a Semi Equal length. I also have the benefits in terms of power/efficiency per said above :D, Not needed but I would also recommend ceramic coating them :D
|
There are un-equal extractors available if u want to gain a few ponies and keep the rumble. I'll be going Tomei when I get around to it.
|
I've got equal, sounds like a Honda.
|
Thanks for the comments guys, interesting to hear that the new xforce gear is regarded as semi equal, is this why there is the claim that you retain the rummble? do Xforce do UEL headers? I should have mentioned my WRX is a bugeye so mainly just need to get rid of the stock up pipe but was told leakage was a problem when fitting aftermarket uppie to stock manifold!
|
David, I'd rather pay the extra for Tomei as I have personally installed and used their other bits and was a joy to fit. Cant say Ive had the same pleasure with non JDM aftermarket bits.
It is a good idea to get rid of the stock up pipe in a bugeye, get one with a flex joint to avoid fitting dramas. |

Good to know if claims are true (don't have reason to doubt Rob) If anyone is interested the Tomei headers gave a consistent power increase across the rev range with a max of 10atwkw improvement with no other tuning required. It was done on a 257 motor with other mods already installed. The test was done in and old ff&r mag I had a few years ago.

Can also vouch that they're the same product, have had both Tomei and the Kando/Ultrex ones in my hands and they are identical aside from the badge. Have the Kando/Kinugawa ones on mine, no issues fitting and no issues have developed. Got a set plus ceramic coating for what a set of Tomei ones would have cost.

Easy enough to fit yourself if you have access to a hoist?

SSI factory in Taiwan make the Tomei and Kando ones, I know as I've personally dealt with the factory when I was selling them via group buys. Only difference in the Tomei branded ones and the SSI/Kando ones is the Tomei name plate and the Tomei/SSI brand stamp on the flanges, the rest is identical. :icon_thum So you'd be paying extra for just those 2 things. |
Cheers all, Great advice!

I have E/L headers and do not have the rumble.
