I dont really mind force induction but headers and downpipe and im satified and im sure ppl will give into this

 

dont waste your money, headers give you very little gain and sound terrible.

 

i think with those 2 parts is another 10-20hp

 

maybe on a V6 or V8 this is true. surely not true with a 1.8L motor.

 

ok well ii tried. im goin just for looks now.

 

I got +7 whp from a header on a 1.2L.

I never had it dynoed but I put a header on my 1.5L civic, and after that I picked up a couple tenths of a second at the strip. I know there other factors but I raced a lot before and after the header and the time gains were pretty consistent.

 

actually yea that seems accurate. well I still think it wld make atleast 10hp. Im pretty sure we can compare to how much the corolla or matrix's ( na 1.8L engines)aftermarket headers and or downpipe would make. if not then xa and 1st gen xb.

 

um let me know if you can actually feel "10" horsepower....25 yes but ten is so minuscule, cutting weight of the car and your body would be more beneficial. And again listen to 4cyl motors with a header, the sound is disgusting!

 

Ya and a header could be 10 hp closer to that 25 that you can actually feel. I would expect most people that are going to by a header will have the rest of the exhaust done, and an intake system, and whatever parts we might get in the future like an intake manifold or something. And hopefully the aftermarket header would be lighter so you can lose a little weight there too. Dont know about all cars, but my Civic sounded the same with an aftermarket header, it was all about the muffler.

 

even just swapping out the filter box for a cone for abit of gain feels a differenc. and all parts would accumulate. (cai,headers,downpipe,exhaust,pulley) and I have heard, but theres not much of a distinction to tell a diff. esp. if you have a full exhaust sytem.

 

If the motor is built anything like the 2az which I guessing it is, you will see very minimal gains from bolt ons. And if a header only makes thes exhaust sound like ____ than what's the point?

 

its not that similar to the 2az but yea diff. opinions. and the point is that minimal gains are better then nothing. Its like why do you have a name brand exhaust if your only gonna make min. hp gain? If noise is all your after. then get one off of ebay for 50bucks lol

 

i think a header might help more then everyone thinks! i dont know squat about the xD motor, but i know its Dual VVT-i and 1.8L, it really depends on how restrictive the factory units are!

also, what do you guys redline at?

 

thank you. Im pretty sure it would make a decent gain. and we also redline at 6.2k

 

good question i think its at like 6.5 or 7k.. but i noticed a big difference in power switching to a 2 1/5 inch pipe..... and noticed even more when i went back to stock and put on the dc sports exhaust...

 

i think its obvious that xD owners are interested however i know that even if i had all 5 grand in cash for a full turbo kit now i wouldn't put any money into a product thats not out yet. i agree completely with yelosub. it takes one person to commit and if the product they produce is worth buying then all interested xD owners will put forth the money. its not like we would have any other choice since no other companys make one.

i wont hold my breath tho i mean the cars in its 3rd year and still no headers who knows how long itll be before any other companies make production turbo kits.

 

i dont think there is enough xd owners interested honestly. If there was enough interest, the ball would have already started to roll. honestly the scion community are not high rollers and thats what it comes down to. There is no doubt the few who are interested would get a great kit, but there is only a handful waiting to take the plunge!

 

Youngflyer, your not an xD owner, you dont know our car or engines capabilities, and your bashing xD owners cause we are cautious.... how did you even come across this thread, and why are you posting in it?

 

im not bashing owners i was just saying that there is not enough interest and if there was, it would be rolling already. i think its safe to say, no one quite knows the potential of the Xd yet seeing as how no one has really pushed it to its limits. however other than the dual vvti, i presume the motor is built much like the 2az.

 

Well if you researched a bit, as you told someone else in this thread that they should, you would see that the motor is not built similarly and an intake manifold, header, and exhaust produces almost 30hp on our cars... but unfortunately you wouldnt know that cause you dont own an xD, nor care to modify one... so again why are you in this thread?




^^^Sounds like bashing BTW...
