What Kind Of Gains With Headers?

[09kx250f567]

I have a 03 sss with a flowmaster catback and K&N intake. I want to get more power from it but dont want to spend alot. What should I get to make it faster? shorty headers? what gains would I get from a custom tune?

Shorty headers are not worth the money since they do not really provide any performance gains........get a custom tune and a 160* thermostat and you will see a big difference.

shorties are a waste, get LTs if anything... tune is worth every penny (live or dyno being even better then mail order).

 

but id even like to know how much the 160* stat would help?

ditch the flowmaster, get LT's, 160 stat, tune . . . . . you will feel a great improvement

custom tune. def go with long tube headers if any. and idk why everyone hates flowmater. i see no problem with them, i guess they say the chambers are restrictive. i dont think it effects performance. i dont have flowmaster but i bet i flow more air then most others with chambered mufflers. leave it, its prob loud! lol

the lower operating temp allows your tuner to pull a few more degrees of timing

really. . . . . .you dont say

durrr.... i swear im retarded sometimes. now if gas would squeak back to under $3/gal I would consider running 93... business has been to slow for me lately to try and afford 93 fill ups.

were do i get a 160* thermostat?

[black00chev]

do a cam, you'll get more HP gains that way and it will be cheaper than long tubes, IMO

Seriously, it's only about 4-5 dollars difference per fill up. Every vehicle I own either runs 105 octane or 93.

 

As for the headers, people have tested before and after with shorty's on the dyno and they do make a difference. With alot of tuning long tubes are worth about 25-30hp and shorty's are worth about 10-15hp. I'm with Justin, go for the cam first.

Do the cam! As soon as my warranty is up im throwing on a lingenfelter stage 3.

[09kx250f567]

can someone post a link to were to get the cams or more info on it. Im only 17 so im kinda new to all this. I fill my tank with 87octane what would 93 do for me?
