ok, I'm showing my ignorance here. I looked at the charts, and while I could make them out somewhat, I'm looking for more of a nartative on the headers. A break down on Pros, cons, and would love to find an overall winner, something that woun't sound too bad with a TRD exhaust (temp muffler, couldn't beat the price).

Ideally I'm looking for recomendations for a header/exhaust combo, got a lot of OT coming in this month, and need to feed my upgrade addiction.

Any feedback is most appreciated

 

bump, i wanna keep this thread going with more info!

Im thinking of going with the Alphawerks header/ ZPI S-pipe and magnaflow catback

 

have you guys considered testing the strup header? I'm looking into it.

 

Were all the headers tested 4-1 or was there any 4-2-1? From the pic, looks like all 4-1. Just double checking...

 

is the DC header now 4-2-1?

 

As far as I know, the DC is 4-2-1. The header itself is a 4-2, then it becomes 1 when it meets the s-pipe. If you look at the end of the header you will see that the pipe is divided in 2. I'm not sure though...

 

...and 4-2-1 is better right?

 

With 4-2-1 you are supposed to find power gains at lower RPM (probably between 3 to 4,000 rpms). 4-1 should show more gains at higher RPMs (I would say above 5,000.

Which one is better is all according to what you are looking for. If you want to race, you probably want a 4-1. If you want to improve your daily performance, 4-2-1 should be a better choice.

I chose the 4-1 becase the tC has good performance at low RPM and is kind of dead at higher RPM. The Megan header brought it alive a little bit after 5,500. If you have the $, you should go with the AW.

I'm no expert, so I don't mind if anyone jumps in to correct if I'm wrong

 

mmw header test!!! please...

 

video clips/ sound clips!!! please!!!

 

Great post to help people decide!

 

i have mmw headers but i have not clue how good it is. but personal reason i hate their service i would put the money somewhere else. MMW them self can't even dyno their own stuff. so they offer discount to people to dyno it for them they stink and engine damper sucks go with the ingalls i learned a lesson.

 

ttt

 

i have a friend selling an alphawerks header for a good price if anyone is interested i know its rare and its like brand new 1k miles well see =D need some funds

 

im intrested pm price;;

 

Just so everyone knows, the DC header is a 4-1 header, not a 4-2-1 style header.

 

I have megan header with stock pipe... I would post a sound clip, but I have nooooooo clue how to do it. It sounds so ricey anyways...

 

cool test!! thanks!

 

Wow oldass thread, but hmmmmm lets get an update. Where are you GSC??? I want a test on the MMW

 

GSC doesn't have a tC anymore. They mainly work on subbies and Mitsus now.
