« on: September 25, 2007, 09:13:25 PM »
broke my exhaust so instead of spending 100 bucks to fix it i figured id spend 200 and just buy a header and build my own system. wondering how this header is and what size pipe i should run for the exhaust

2" or 21/4" if you have a lot of bends.

Mine has worked well. Hes right with the pipe,  mines got 2.5" to a flowmaster and 2" out and I'm sure it effects my torque in a big way and several other issues.  But on the plus side it sounds awesome and can set off car alarms as I mull through the gears!!!! ;D 8)

Yes, I tried a piece of 1 7/8" and was too small,was a major difference going to 2", you can mess with cam timing next for low end power. buy a pully or do the chevy key trick, cut a degree key in half and put it on the crank shaft.

ever mess with small block chevy's? take a woodruff key for a small block that has the top half shifted over to one side, depending on wich way you put it on the crank and how much shift you buy, try summit or jegs ect. and you have to cut it down in size to fit your much smaller crank shaft to move the bottom pully over just a little to change your cam timing, there is a two to one ratio with this so it does not move it as much as moving the top cam pully, if you do not understand it now you need to talk to some one localy that knows about engines a little bit more to see if that is what you want to do, mine is a big toy so it does not matter what I do to mine but maybe yours is your only rig and it has to get you to work or where ever,LOL  have fun p.m. me if you have anymore q's.

Loved my DT headers, never bothered with the heat risers though. Figured it would lessen warm temp power. I used a glass pack Cherrybomb and 2 1/4" It had a pretty good ricer sound that I never loved.  Used a 2 1/4 cat if you were really focused break up the honey comb catalyst but it won't fool the tail probe should you move or your local laws change.

As to you're question about the 1.6 16valve wiring Trail Tuff makes a plug and go harness. But its not cheap. It may be cheaper to do that 4.3  ;D I have a Thorley header and it works well through a 3 chamber Flowmaster and high performance cat. Its smog legal in the Peoples Republik of Kalifornia too.

Have you seen how much a junked catalytic converter goes for as scrap?. to give you an Idea, someone on this forum I used to go on(tercel4wd.com) sold 2 very rusty tercel catalytic converters on ebay for $285. Its no wonder thieves are stealing them. The same goes for copper.
