top speed header

[snYpz]

^ thanks Aaron.
But dang what a disappointment. Engine response was awesome after the install. The only drawback is the rattle sound that occurs with increased throttle....arghhh!!

Could it be that he didnt replace it with a double braided flex pipe?? Or maybe should I give it a few weeks for the parts to adapt?

I will record the sound if possible later tonight

EDIT --> Could not record the sound. I will give them a call to see whether it could be the flex pipe. Car is alot more responsive tho

i have the same sound as well.
the guy at work shop told me there isnt any leak. i think u just need use to it.
i decide change to injen intake and see if there is any different.
but i feel the car become slower after i put topspeed on.
am i feel wrong or it is normal.
the car doesnt have much response at low range.
also, the guy told me, maybe i need replace the cat and intake as well.
so, right now, i just try to use to it.

changing to injen CAI will cause you to lose low end power---> lose of low end throttle but you should be able to feel the difference but not as much.

and you will need to wear in headers and let the ecu adjust to it.

so, do i still change to injen or not?
cuz i heard injen intake gives better air flow, but im not sure what happened when work with topspeed header?
so, what my will looks like when i done my injen + topspeed?
do i need go to dyno and adjust my ecu?
cuz im not sure i will stay with topspeed forever, i may change back to stock or other brand later.

I have comptech icebox, topspeed headers and magnaflow cat...

The sound isnt like the whistle that most ppl with dc and topspeed headers complain about. The person who installed my parts will have another look sometime next week to look for weaknesses in the weld and play around with the flex pipe.
Performance wise, there was definitely better response down low but the "leaf-rattle" like noise is my only complaint at the moment.

Injen u will lose some power down low but the sound from the injen at higher revs might camouflage the sound from ur headers.

thats weird when i changed to SRI i felt like i lost low power...

did you make a CAI pipe to your SRI?
that could be why and was just heatsoaked.

Cause when i just had pure SRI with nothing feeding to it i found that it struggled in extreme weather like how we have now 30deg above.

Another thing that can help the SRI is the box it up as the engine bay heat would be restricted from the pod. <--- yet to do
Also alot of people like the CAI sound compared to the SRI as SRI sound really rough like a rocket. CAI sounds really smooth with a slight blow off sound from sucking in air.

nope i just had stock air thingo then i bought SRI off net and got it installed, and now i feel like it has a loss of response in the lower revs.. like if i WOT there is like a lag before it gets up :S i'll try get a video, it might be cause i have an auto/semiauto

just curious what brand also?

hmmmm a bit strange finding it lag though.

yeah i know i thought normally u get this problem with CAI not SRI.. maybe they messed up something with installation

Will give you better flow and mid/high end torque, and the headers should give you low/mid range.
No you don't need to tune, the Euro ECU will relearn the better airflow.

could it be your filter your using? which reduces air flow?

[johnprocter]

its the same filter in the photo why would that reduce air flow?!?
