so has anyone dyno'ed this header besides mmw? i know the header they designed for the 2zz is crap, performance wise. they stated it was a race header, yet it lost power up top compared to stock. theres a company in arizona called PPE that just designed a header for the 2zz that picked up about 13whp on a car without a tune. i know the mmw header looks nice but does the one for the tc perform?

this guy has a mmw setup and he got close to 30 whp w/ a cai and a axleback, and the cai and axleback's gains are almost negligible.

^Im getting mine installed within the next few weeks. I have the s/c so ill keep you guys updated.

mengsta

Cool would you mind telling me how much/ where u getin it from?

JPsTc

So it definetly pulls harder on the top end. I do miss that low end torque, but ill live. I had the injen exhaust on it and it sounded sooo rice. Took it off and put the stocky back on till I can afford the dt-s.

mengsta

That sucks so u lost low end? i thought 4-2-1 r supoesd to help low end. You on the stock midpipe right now?

milkman713

It doesnt really help it except for the fact that you get to keep more of it as opposed to a 4-1. oh and jpstc im pretty sure when you get the dt-s your gonna love it. There is no rasp and its just a little louder than stock like the trd.

mengsta

Oh ok yeah that would make sense. " It doesnt help it but the loss isnt as bad as a 4-1" right? got it. lol

JPsTc

Your loosing some of that low end because theres not as much back pressure. But its worth the gain on the top end. Oh and milkman, yea I can't wait to order, ive been hearing nothing but good things about it

mengsta

You guys have that weird sound comming prolly from the spipe connecting? sounds like little metal peices rattling, im starting to think its a leak.

prolly not a leak. just some heat shield or something rattling. check to see if your s-pipe is hitting the metal bar, or see if there's enough clearance. if not, wedge something between them, and problem fixed.

mengsta

Nuh i know its not actual metal to metal rattle,its a bit more quieter then that, and ive had my share of heatshield rattles but thats now fixed, damn tsudo. ITs cool if no1 else has this , ill check this weekend.

JPsTc

Let us know what you find, because i think i have the same noise.

TCpete

all of us do.. i know what it is.. its the spipe hitting the output shaft and also it might be the header hitting a small notch on the subframe... lol been there done that lol

mengsta

Hey pete havnt heard from u in awhile, The pipe should hopefully come by 2moro, sorry for the confusion, ive just been busy with work, girlfriend.... Oh but i got off house arest already. Well anyway this sound im getting really doenst sound like metal rattling, atleast i thought it wuld be a bit louder? or maybe it would vibrate the car a bit, But it as this distinct sound of like metal shaving off or something. especially wen i gas it from 2k rpmto like 3.5. Im starting to hate MMW headers too, shulda went Mazzuri.

mengsta

Its not leaking, U guys r right, its just a slight tapping, which is why i dint actually think it was a rattle.
