Was wondering about these headers for the firebird formula i need some headers i read that the y pipe at the end where the cat goes is only 2.5 inches could i just cut the pipe off and get a bent 3inch pipe installed.


heres the link for the headers.

too long of a sig

edit: and why would you buy z28 valvesprings just to replace the heads with the worlds that can easily take a "lt1" cam's lift.

 

im not going to put the 305 heads till a year later right know i just want to get the lt1 cam in.

 

also the springs are only 23bucks.I can give that up just will have to drive normal for a week or to no flooring it.

 

Oh ok, buddy...
How many miles on the motor?

 

well friend

117,xxx

and it just braley burns oil hardley any.

 

Agreed. A little off topic here but in your sig you listed a 2000 GTP as a kill, may I ask how you managed to win that race, I've always thought GTP's were solid 15 flat cars maybe faster.

 

I really dont know about this guy. :lala:

 

So you are planning a heads/cam swap on a 100,000 plus mile motor. Right now as-is are you running a catalytic converter?

edit (notice I know how to use this button): According to you sig, you are still using a cat; take if off and see how much your car smokes. I would bet that that smoke is burning oil, and cats do a pretty good job in hinding it (first-hand experience there).

 

well i guess i forgot to take it off my sig but its been off for a while and my car dosent smoke when its on only if it sits for a week and then when you first turn it on it smokes barley then after its on for like 1 or 2 minutes it goes away and i never said that i wasnt going to rebuild the engine soon.

 

what do you mean you dont know in a good way or bad.

 

edit(notice i dont give a @#$!) has anybody used the hedman headers that dont come with the y pipe there 119.99 and then the y pipe is 99.99

 

Those are on my car right now. You dumb *** that's a new post not an edit. Good luck on your car though, I can tell with your knowledge and skills it will be kicking everybody's ***.

lol

 

hey quiefer any time you want to go just let me know.

 

just palying.Anyways how are those headers treating you are they good performance for the money have they made a difference in performance?

 

I'm happy with the headers, although they are the only ones that I have ever had on this car. In stock form the headers are good, it's the y-pipe that blows. The collectors on the y-pipe are rough as ****, and resemble nothing of smoothness. I fixed that with a high speed die grinder (powered off of compressed air). After that its the single 2.5" pipe that sucks. I took a saw-zall to that and cut off the single 2.5" pipe and threw it away. The shop bent and installed single 3" in its place. I went from a stock setup to a headers/no cat/all 3" setup all at the same time (IMO the way to do it). The headers went in pretty easily, and the collector bolts aren't that hard to get at. Surprisingly, I didn't notice a huge difference; although all I had was a worn out 305 with a Stealth manifold and holley 600 CFM double pumper carb. I bet that if I switched back to the stock setup with my current mods it would be deathly slow though...
