Downside having the Tomei is that you would have a significantly lower output should the car be supercharged. It's not going to flow as much as 2.5" will.

The runners are not 2.38", only the collector to the overpipe is. Both EL and UEL runners are same diameter, and collectors are same diameter.
Stock and Tomei runners are 1.68", JDL are 1.75".
Stock collector 2.02", Tomei collector 2.38", JDL collector 2.5"

So you think I'll get more low/mid end torque with Tomei vs JDL but sacrifice some top-end power?

I read your post. That's why I asked if it would be a BIG difference in the top end...

the tomei are 4-2-1 while the jdl are 4-1 so you have to take that into account also

The Tomei UEL is a 4-1 no?

the uel is 4-1 while the el is 4-2-1. i was referring to the el as comparing to the jdl

Will work on this. The dyno charts I believe are on their site but the sound clips will have to wait til these arrive here.

I was just wanting the torque numbers

and of course sound

NyC Zn6 · 07-11-2014, 09:17 AM

Anyone know the eta on these headers? Would love torque figures on UEL if any vendor knows.

Killianti · 07-11-2014, 09:23 AM

They should be released on the 25th. If you preorder, it will probably be shipped on that day.

akahenry · 07-13-2014, 07:22 AM

AS SOON AS THERE ARE SOUND CLIPS OF THE TOMEI UEL, I WILL BUY ONE FROM A VENDOR. UGH. I NEED RUMBLE IN MY LIFE AGAIN.

calmtigers · 07-14-2014, 06:23 AM

I guess Tomei japan won't be releasing any sound clips or more numbers? It'll be up to those in the first wave I guess

excited for the 25th!!
