I just installed my headers and noticed no gain in horsepower. I just got it dynoed today and noticed a loss in power and torque. Is this possible? I am so depressed. I am selling my headers for $200. Who wants them?

your headers, might be leaking, get them retorqued. some of the CL-S folks had this problem.

I don't think they're broken. I don't really notice much of a difference at all with mine. I do feel a loss of low end torque. Maybe above 5500 rpm's there's a little more power, but I CANNOT justify the price to anyone looking to get them. Way too much money for what you get...

But they do look cool

Sorry guys, I thought I was pretty obvious by claiming that there was no power gain and the fact that I was getting rid of them for $200.

Ok, shame on me.... My BaD!!!

mr tl

if you dont notice a power gain they were most likely not installed properly. supposedly torqueing them plays a big role

everyone says they feel a difference with the intake, the headers give about double the power of an intake. and unlike the intake, the headers show gains all across the power band. in a few months im going to decide between headers and rims

i know there was a dyno chart a while ago

you will probably notfeel that much on a non type s model your probably get an increase of maybe 15 to 18 hp

I'd notice AND be happy with 15-18hp.

AcuraTL

Yes, there's definitely an increase in power. The faster you go, the more gain there is. I have a 99TL and in 3rd gear from 80mph to 110mph, it flies. Much better passing speed. I usually leave it in 4th gear when I pass people on the freeway.

You are correct. A header increases the exhaust gas flow speed out of the engine by reducing the back pressure. A side effect of this is that there is a definite lost in low end torque. However if the header is functioning (tuned) properly, there will be a gain in high end horsepower. The engine rpm will also climb up faster.

You will also need to change your exhaust pipes and mufflers to get and feel the best effect with headers.

Nate

I'll post my observations soon!

Guest

I highly highly doubt that you'd ever get that much power gain out of headers. Companies always make those outrageous claims, but when you put it on the dyno you really see what you're getting. Don't buy headers expecting that kind of power, or you'll be disappointed.

Is there a real difference with the headers..can some one tell me the truth?..I want to get them after my body kits but I read yes and no...

StylinTLS

Haha...Imma say this again. Hi-Flo cat ppl. It's about 200 more of a pain to install. But you'll definitely feel more. I'm sure headers and hi-flo would give you even more but for those on a budget hi-flo is the way to go.

AcuraTL

Yes, you can tell a difference...especially after 3500rpm.

typeR

...I DONT UNDERSTAND!!! why so many people talk out of there ass specially when there's so much info available on this site...i can show you right now 5 independant different state dyno charts that show a minumum of the 30 HP to typeS j blocks wanna bet howa bout the price of the headers???dissapoint that!!!! ...

dont disbelieve everything you read...also notice that at around 6300 theres a 35ftlb gain in torque thats nice

Ask in the CL fourm everyone will be all over it since it give 30hp to the type S.

I was being honest about not being at all impressed with the performance after the H/E/I install. It is barely noticable even at high rps's.

I also agree that there may be something wrong with the way they were installed. Although they were done at an Acura dealer, it doesn't mean it's correct. I am having them checked out during my 15K service. I am 85% sure that's going to be at Park Ave Acura, it's a hike for me, but sounds like it's worth the trip.

(Plus the 15K mile service is $199 there and it's $435 at Greenwich Acura

Hey hey, come on now... I was only playing around. Cut a brother some slack, i just go the headers this week.

By the way, a local service/repair shop quoted me $95 to install my headers, do you guys think it is worth it? I don't know about them. I think I would feel better if I paid $220 at the dealership, because of warranty and other issues related to service if there was to be problem.

I'm seriously considering getting a Comptech header for my 2000 TL. I'm well aware of the various dyno plots where people post quantitative gains, but I'm looking for qualitative gains.

1. Do you FEEL the difference? And if so, how big of a difference?

2. Do you think the gains justify the price... i.e. if you had it to do over again, would you still order it?

3. Does anyone have any dyno plots from an otherwise stock TL/CL (non Type S) before/after the header installation?

Any insight is appreciated!

i only paid 75$ for my 15k service

very nice, i must say.

WOW, then I'll shut up. I've never seen that much of a gain from headers. That is amazing....are you sure that isn't a fluke?!?

I think is a no brainer Park Ave Acura is less than half the price and you get Jens to work on your car. I think its worth it even if you have to drive a couple of hours.

typeR

...not when everybody has the same fluke the only reson ill give you a break is cause it is reall unheard of to get those kinds of gains from headers but it happens on the type S which i have so ill take it

Whew...thanks man!

Ok, after my day trip today, I can say that headers DO make a difference. I drove 475 miles today and I averaged around 90-95 MPH through the whole trip. I can say that there is a very big difference after 85 MPH. That is nice if you drive like I do, but if my headers are installed properly, the loss of low end power overrules the gain of top-end power and I still say they weren't worth the money. The dyno may say a big increase in HP, but it's MUCH better on paper than on the road.

The exhaust on the other hand was worth every penny... not in performance, but in looks and sound. It sounds much more aggressive and looks REALLY good (I don't have a body kit).

typeR

what kinda of exhaust???if you have a leak anywhere or to free flowing an exhaust you coould of lost low end torque only a dyno will tell

Acura3200

We'll see after my 15K service if everything is correct. I'm not having my car dyno'd. I just really don't care that much. I bought them, they're installed and if I'm told they're correct, then so be it.
