summit headers

[BRAAPPP420]

i just ordered a set of the summit shorty headers for my 94 chevy silverado..will these headers make my truck sound different?

itll sound a little bit deeper but will result in about a .005% performance gain, shorties are realy a waste of money, longtubes cost only a little more and give wayy better gains and sound

When i installed shorties on my 90 with a tbi 350, i felt increased throttle responce and it pulled a little bit harder at a low rpm, nothing crazy but it was noticeable. it sounded exactly the same.

yea, i mean they are okay with high flow cats, they help the slightest bit on obs, but do absolutely nothing and shouldve never even been manufactured for nbs and nnbs

from what i hear, the stock manifolds on the nbs and nnbs trucks are basicaly cast iron shorties and they flow just as good as most aftermarket stuff.

are they long tubes or short? If short, you should have went with ebay ones, they bolt right in place of manifolds or you can get the flat flange kind. It's cheaper or the same price as summit black painted ones too.
