good to see a fellow k5er in here if your truck is mainly stock i dont see any header doing more than another would for you i have flowtechs and they work fine for me i have true dual exhaust with flowmasters 40 series and 2 1/2 pipes and that works fine for me also yes go to dual exhaust single exhaust just doesnt look right well hope i helped <IMG SRC="smilies/bounce2.gif" border="0">

Flowmasters are the way to go for sure..And Dual exhaust is a must for breathing..
Don't know about good headers of quality for under 200... spend an extra 100 and get a set of Doug Thorley's..
Good headers for low end torque which is what you need on a 4X4....

drnut · 08-23-2001, 09:18 PM

Dough Thorly headers i have heard are the best for low end torque. If your engine is not really modified i would run dual with 2" pipe. I ran 2 1/2" pipe and i ended up with less h.p. and torque due to not enough back pressure in the exhaust system. What ever you end up with buy quality headers with a really thick flange (where they bolt to the block) and i would also recommend either some sort of coating (Jet), stainless steel, or nickle headers. The painted ones rust really quick. Good luck

Doug Thorley's - Spend the extra 50-70 to get the quality product.

SlyDog · 08-23-2001, 10:58 PM

If you are running a stock motor or not going to turn above 5K I wouldnt spend the $ on headers. I dont think you are going to gain any torque, as a matter of fact I think you will loose some with headers.
Can any one of you guys say you felt a difference on the bottom end going to headers? Good or bad?

reddwarf · 08-24-2001, 07:59 PM

If you really mean 200 rpm, I'm not sure, I don't even think mine will run under 400, but...I have seen a dyno sheet comparing Tri-Y headers with 4:1 headers. Below about 1500 rpm, the 4:1 actually made more torque than the Try-Y's(Doug Thorleys are Try-Y).

You do want the smallest primaries you can get (1.5") with long 2.5" collectors and probably a single 2" Flowmaster or similar performance muffler.

Brutpwr · 08-24-2001, 10:07 PM

200 RPM? I'd have Headers by Ed make a custom
set with 1 3/8" long 40" or so equal length primaries into dual 2" exhaust. Otherwise just get the Doug Thorley's preferably Jet Hot coated and use dual 2.5" pipes. Forget the Flowmasters and spend the money on the Edelbrock mufflers (put them as far back in the exhaust towards the rear axle as possible and use a 2.5" H-pipe up near the transfercase. All my friends and I swear by the Edelbrocks (we all have used Flowmasters). In fact I still have one 2.5" Flowmaster 2 chamber to get rid of...

OHHH! <IMG SRC="smilies/rolleyes.gif" border="0"> <IMG SRC="smilies/laughing.gif" border="0">

Go with Flowtech Afterburners. Great header, good bottom end, good fit with no leaks. Under 150 bucks.

drnut · 08-25-2001, 08:11 PM

WOW.. $200.00 is not going to get you much in the header department execept some cheap shit ones. I would save the money and use it for gears or something that would net you more horsepower for the dollar compared to headers. Good luck

SlyDog · 08-25-2001, 11:44 PM

I would do that except my whole exhaust is wasted and the gears wouldnt do shit if i couldnt drive it <IMG SRC="smilies/biggrin.gif" border="0">

reddwarf · 08-26-2001, 07:32 AM

Have been running the Afterburners for about a year now. They still look like they did at 1 month or so, and I have blown one collector gasket, but no leaks around the exhaust ports.
I like them <IMG SRC="smilies/cool.gif" border="0">
