long tube or shorty headers??

[wood]

Been researching headers lately and I know now get ceramic or stainless steel. But Do I buy shorty headers or long tube headers. Is there really a big hp difference.

Longtubes for sure. Lots of threads on this. Shorty won't really do anything the stock shorty headers flow decent already so longtubes other wise its a waste of money.

Got it. Thanks.

Honestly it depends on your goals, shortys are good cause they add a few hp and are easier to install and cheaper, and if the trans ever has to come out (common in these cars) then the longtubes have to be removed where the shortys don't

It's up to you, but if you get shortys you'll probably wish you would of got longtubes

For the horsepower difference I would go Longtubes over shorty. Plus how often do you need to take out your trans

Well depends if ur past 50k could be any day then clutch around 80-100k maybe more depends how you drive

My buddy went 12.5s with
Shorty headers
UD pullies
Tune
JLT 2
Throttle body
4.30 gears
So shortys can't suck that bad, it depends what you want you know, if your going for horsepower and racing longtubes all day but if you want a little more power and louder exhaust just get shortys

Longtubes for the win and if you are going to be doing anything but having a little fun in the car don't waste money on coating. Just go with the stainless.

I installed my ceramic coated longtubes and assisted in a stainless steel Shorty header install.... they both require damn near same amount of labor... I did not notice an increase of power on his Shorty headers... the sound changed a Tad... but not much... the reason 3v make more power then 2v is because of the intake and exhaust system... the OEM exhaust manifolds are damn near identical to aftermarket Shorties... that's why you won't see much of an improvement in anything... I was not happy w the lack of "gains" my long tubes gave me... I do believe it has a lot to do w my email tune... if I were you I'd pick up some stainless steel obx or American racing long tubes... go through eBay a few guys local to me are running em an have had zero issues... fyi make sure you pick up a can of copper coat... it will seal the headers to the gaskets and the gaskets to the motor... out of the 5 people including my self that recently installed headers 3 of us used copper coat the other two did not... they had leaks right off the bat and had to make adjustments... we did not

On my 07 I did LTs,high flow cats and H with CAI and 93 tune all at the same time and it was like a kick in the seat of the pants. Night and day difference.

It's the tune you feel because of the throttle response,

And silversky the reason you don't feel the header improvement is cause its all top end, I pull like 4 car lengths on my buddy's gt but he will start pulling back up top end, not enough but you can tell its there

That 12.5, the 4.30 gears had a lot to do with the time.

No.....it was the 4.10s lol.

I feel it down low with lts. The car dam near pulls the wheels now.

The Shorties do produce a LOT of power. Less than the Long tubes across the board but they DEFINITELY do more than 'not much', In the last thread discussing this I put up a half dozens dyno comparison SHOWING shorties get significant gains. So for the price, they may be worth the sacrifice of HP. If you aren't installing yourself, shorties WILL be cheaper to install.

See above. The LT is NOT all top end.

Headers

That is the link to the post with the dynos showing both headers get great gains and while the LT DOES get MORE up top it is NOT only up top. It gains across the entire band.

So how much do you think shorties will gain in hp

What are the supporting mods?

If you put on a Cai and shorties with a x pipe and a tune.

[Silversky545]

Op if you want true tech help join another forum... this forum is for making fun of all the " what cai should I get?" Threads....

I hate to play this game because dyno gains are only as good as their dyno but you can expect 10-15whp through out the range +/- 5. I would have to equate that to a .15 or .20 in the 1/4.

It is all personal preference.

Thanks for all the info.
