I'm wanting to put a header on my scion. On case it matters my current mods are strut bar TRD Short Ram intake and my exhaust is just a glass pack.. Yes haha little performance but for $180 sounds great. Anyway I was wanting to put a header on and if I do that do I have to get like a custom exhaust, mid pipe and stuff? Thanks for the replies!

 

you don't have to, but it would be optimal for better airflow imo

 

the bigger the piping (to a certain extent) the better the airflow will be, so anything other than stock will be fine. It all depends on what you are wanting out of your car, I would say just go with an exhaust first as the headers tend to give off a noise that not much owners like.

 

/\ yep, headers will give off a raspy sound that gets kind of annoying sometimes. It can be somewhat fixed by welding in a larger resonator to your midpipe though, which I plan to do when I can scratch up some extra pennies

 

Number one, you don't have a muffler, only a glass pack and you think you gained performance? I find this hard to believe because on an N/A for cylinder motor it need that back pressure to give it that pep. If you started with a stock TC, took the axle back portion of the exhaust off (muffler), then raced around, you would notice that not only does it sound like crap, but it will feel like it has half the power. I only know this because when I had my N/A set up on, stock header, invidia midpipe, I took my TRD axle back off in my driveway because I was planning on installing my ptuning exhaust, then my buddy called me to bring it a couple of towns over to his shop with a lift, so I drove over there very spiritually with just the midpipe and it was gutless, when I put the ptuning exhaust on, I had my power back. It made such a difference that even my girlfriend said she could feel it.

Number two: what kind of intake is that?

Number three: if you really want to add a header, you can. And my choice would be the DEZOD Green header. Everyone says we get rasp with a header on our 2AZFE motors. Well, I think Dezod pretty much squashed that. Now you can have an American made, crafted, and designed header, that uses a catalytic converter (high flow), and will eliminate rasp. And by the way, they're on sale right now on their website. I hope this helps. Keep modding!

 

I'm running a full Megan setup on my tc and its pretty damn obnoxious. I leave my silencer in at all times though, so I sound like a kazoo. But it's a totally noticeable gain in power. Still slow... But not AS slow.
