Apparently this one doesn't understand the concept of a metaphor.

I said A car, not YOUR car...Lincoln towncar, F150, Kia...take your pick. We're talking about power differences that don't show up until you have WELL over $20k invested in power mods, it's not something you're going to see at or anywhere near stock or stage 2 power levels.

EL EXTENDS the shorter runners to be just as long as the longer ones. People keep saying that this somehow lowers temperatures. Use your own logic.

That's what I have always heard as well. I don't know why ppl say that but after removing my oem headers and replacing them with my tomei headers I could see how they might have some impact. Maybe not on egt if anything just increased flow. It was interesting to see how quickly the two exhausts came together (oem) so quickly out of the head. If I didn't have a job a wife and a new baby maybe I would have time to research such things.

Oh ok so there is no solid evidence that EL headers are better in regards to lower cylinder temps. Cool thanks for clearing that up

Except, I wouldn't be so worried about a well made header cracking so much. My AP header flanges were like 1" deep inside the runners.
Any specific reason the KillerB headers are much more expensive?

Anyone have a clue what brand these might be? Im guessing they're knock offs due to the fact that they're unmarked, one piece, and some dude sold them to me for $50... If they're crap then at least I didn't lose out on a boat load of money

well first observation is that weld at the very tight looking U bend for the short side, and no adjustment. Hopefully it bolts up! Since it was so cheap it wont be much of a loss if it doesnt work out. Hopefully you dont get it installed pay ~400 dollars for a tune and then it cracks a month later.


i searched ebay and some vendors and dont see anything with that same design. the closes i could come up with was this http://www.ebay.com/itm/4-5-Muffler-...1e9abf&vxp=mtr but its different.

So i just realized good luck snaking the up pipe through there if its all one piece. might be more trouble than its worth imo.

Yea like I said, if they don't work out then it's a nice ornament for the man cave... Btw I did a bit of looking around myself and the closest match I could find was an amazon set for $200 an they're supposedly mfg'd by BP... Only baby Jesus knows, the only way to find out is tear the old girl apart and slap them bad boys on there

I think he was referring to the $50 dollar header and not invidia.

I just got GTspec EL headers and tuned them and let me say, wow what I bang for buck, it's all smoothed out and a very nice power bump it also doesn't die off like it used to, I got power all the way to redline. And it still sounds like a Subaru! On the outside anyways, inside the car it sounds more like an Evo. But I let my friend drive it and it rumbles all the way down the road, it's just not as obnoxious anymore

$50 is a hell of a deal. They are $250 headers lol.

defiantly not Megan's, Flex pipe is smaller and the bends on the piping is slightly different.

So, for 500whp setups or smaller, aftermarket EL or UEL doesn't really make a difference other than sound. I'd only go with the grimmspeed setup if you're worried about cracking a tubular header, because it's going to have about half the gains of either aftermarket UEL or EL.
+1 on wanting to see these plots. Granted, maybe the overall max gain is not extraordinary, but I'd be more interested in overall area under the lines. That is really what matters. Do you gain more area under the curve? The merits of EL design are clear and should yield gains.
