Loslam Posted May 25, 2012 Report Share Posted May 25, 2012 At some point this summer I'm gonna do a cam, shorty headers, another tune, and redo exhaust with new cats and h pipe. I'm trying to not sink a lot of money into it. I know the 'you get what you pay for' rule of thumb but sometimes it has its grey areas. Name brand headers are pretty expensive over knock offs, so I was wondering if these from ebay are decent or not? Minor fitting or issues I think wouldn't cause a problem since I'll be redoing the exhaust header-back anyway.

b-dubs89 Posted May 26, 2012 Report Share Posted May 26, 2012 don't know alot about headers but i would be willing to give those a try , i think if you buy those headers you may want to spend some money on good gaskets and some locking fasteners . it sounds like header bolts can be tuff to keep tight . they like to rattle out or loosen up Quote Link to comment Share on other sites More sharing options...
badasschevy Posted May 27, 2012 Report Share Posted May 27, 2012 i would look into a mid length or full length header,the biggest issue with these trucks is the 1 7/8" down pipes off the manifolds. i tried shorties on mine and noticied a little better performance. i now have doug thorely tri-y's,with 2.5" downpipes into a universal y-pipe(2.5" in/3" single out) into a highflow cat with a 14" magnaflow muffler with it dumped right after the cab. the performance now is quite noticable down low(torque).

Thanks for the advice. I would agree with you on long tubes but money is kinda tight these days, and I have to start saving up for my college meals come this fall lol. Still deciding at this point, but if there are any issues in terms of fitting just about anything will be fixed with a welder. I already have true duals but there are so many leaks it sounds pretty bad at idle. Just gonna redo 2.5 duals all the way back and new hi-flow cats Any knowledge on cams and how much lift I can have with the vortec?

xh3mpx Posted May 30, 2012 Report Share Posted May 30, 2012 (edited) I'd fork out a little more cash and get Hedman Or Hooker headers.. You'll have less problems with them.. Edited May 30, 2012 by xh3mpx Quote Link to comment Share on other sites More sharing options...

87chevyboi Posted June 3, 2012 Report Share Posted June 3, 2012 ive never heard of those headers, but the rule of thumb in my book with headers is if it breathes better than stock then it has to be better lol i feel u though ive build alot of motors well about 4 or 5 and ive ran name brand headers and non name brand headers but the only things that you'll see in difference is on some of the cheaper headers the dyno numbers will he lower but not everyone has a bad hp drop. check em online Quote My build aka Snow White whats wrong with fat chicks? they are like mopeds, as long as your friends dont see you riding it, they are a blast! hahah I am dumb as a stump. I live in the south and we are all dumb here. Link to comment Share on other sites More sharing options...
