Thanks, Jam

 

it will make your car louder and gain some HP... with a reflash + headers you'll gain more

 

if money isnt a problem get the Impuls

 

okey thanks but what is reflash?

what is impuls and what it do? can u show me a link of it please

 

Wow, def a new guy to the car scene. Ok, reflash is changing or "flashing" your car's computer that controls the engine management. This is done to adjust the air/fuel ratio along with various other things.

Impuls is a company that makes aftermarket parts/accessories for cars and is one of many. Go to www.froogle.com and type in G37 "insert part you're looking for here" and browse. I also suggest you browse the following sections just reading and learning things about your car and what's available for it.

Here are some links to sites that carry parts for the G37:

and course there's searching through eBay

 

Has anyone beside the manufacturer actually quantified the added gains from headers? I ask because the car already has tubular headers from the factory. People can then decide if they are worth it.

 

Good question. Anybody? Bueller Bueller?

 

I've heard in the past that the stockies flow pretty decent and the aftermarket ones are just not a good bang for the buck. I haven't done this personally so I can't verify that.

 

Do a search, there are guys running headers with a tune and showing 20+ HP

 

neverbonestock is the only one I know off..

c@ciq got them shipped but not sure he installed them

 

How about AZG37 that sold them a long time ago, and the guy that did the reflash with technosquare making 350 hp to the wheels

 

I've got the stillen headers installed... those, and CAI and Cat back have combined to make my car pull harder and sound more aggressive, especially at WOT.

Next week (I hope) the HFC's, Wheels, and springs will be put on (and a spoiler).

I haven't dyno'd my car, but it's something I'd like to do down the road when I get a tune or install the cobb AP and try the 2+ map, since it was designed for the airflow mods I've done.

So to answer your question, I can hear 'em, feel 'em, but I ain't got any numbers on 'em When I'm done with everything, I'll get some pix/vids up.

 

have a look at this dcook

I took at look at that link, which was pg.2, not sure what you're getting at Sam. Are you saying headers are worthless or good? Page 1 however opens with:

" ...My review No gains from headers and loss of Torque. Final report. " and a graph.

So must be that's what you're referring to...?

Either way, don't matter now! I'm not going to uninstall them! If headers don't do anything, then the increase in power I feel must be from the CAI or the exhaust, or a little bit from each. Who knows dude. My goals are simple and modest in the grand scheme of things: throw on some bolt-ons, some wheels and springs, tint, and maybe a cobb and be done with it!! In a few more weeks my goals will be met, and I'll be grinning from ear to ear .

My car will probably never meet a track, but you'll see me smoking people on the Merrit Pkwy lol. Knowing me, I wouldn't bother with a track unless I had FI - not that the car's not capable, but that's just me.

 

Please dont waist your money on the cobb
