Wow. Now let me tell you the obvious problems about your post. Not once did i say they helped power wise because hoenstly they dont help enough to notice. The spider did because mine was pretty bad but it just brought it back to where it shoulda been in the first place. I was just stating that other than those 2 things my engine is stocker then stock. And being that those are aftermarket mods they, by definition, are not stock. I know they arent squat for helping powerwise. My truck is closly related to the OP's truck being both l31 ecsb half tons so i figured i would share my experience with him since he was asking about headers. I shared my honest experience before he spent his hard earned money on things that dont have a noticable effect on a stock motor. Now if you do some other power mods at the same time you may notice a little on the butt dyno. Now, Mr.Knowitall, if they can get back to the subject of the thread instead of you telling everyone why theyre wrong thatd be great.
There is nothing you can show or tell me to make me think that any of these 99% stock l31 have any noticable power increases from headers.
Weve been over this like 3 times already. THEY ARE DIFFERENT SIZE. We both know that. Im saying the smaller one is still more than adequete for a stock l31. i understand why you would need larger piping, you have a ramjet cam, head work, and 1.6 roller rockers, i have read the thread, but yours is gonna be moving alot more air then stock. I, on the other hand, have absolutly no use for larger piping. It wouldnt gain me a single hp because i have a 99% stock engine.
