Thread: Significant gains from headers over power log?

headers flow better. its a no brainer.

im personally not 100% sold on the ultimate gains of headers over a plog/downpipe setup, but so far every header car dyno'd makes more power per mod.

No. The old timers use to just have PLOG, DP, ported mani's. There's a reason everyone went to headers, especially since they're are a fraction of the cost of what use to be available ($900 TOG's anyone?)

I know headers flow better but does anyone know of any actual dyno results with a plog+Dp setup...I already have a DP so just getting a Plog wouldn't be putting my out to much money...I want to go with a cam eventually just trying to figure how much power the Plog and Dp leave on the table compared to headers...btw I can find tons of vids on youtube but they all have headers

I think the horsepower gains are honestly about the same...to an extent. Lets say 2 typical bolt on 3.4 setup GTPs ( not a serious build) one has a plog/downpipe setup the other with headers. the plog downpipe one might put something like 230whp while the header one may put 230-232whp.Its not much difference hp wise however once you get into bigger more serious builds then the gains from headers would be larger more then likely. But otherwise flow is key.

Id trust a PLOG more to be honest. Im one of those "old timers"

Ill bet KR will be lower with headers everytime. In my mind thats the ultimate goal

The best option is do what you can afford, f**k breaking the bank.

for some people its just that the header install sucks, if you don't have access to a lift

A lift for headers? a set of ramps does the trick!

Sell the d-pipe on ebay and get headers

sd headers= same price

a lift makes it easier though i would assume ramps will work yea but lift is alot easier

Yeah when I bought the DP I wanted to go SD headers but having to weld in a new flex and bang on my firewall didn't seem ideal to me...now I am thinking that someday I would like to get a NIC cam but not anytime soon...just trying to gauge how much power I would leave on the table with plog dp if I end up going with the cam...also since I have 150+ into my dp I wouldn't really be much farther ahead by selling and getting headers price wise

What would you consider a serious build?

And?

A big cam,ported heads, ported everything, intercooled, bigger tb, all that good stuff thats def worthy of headers over any exhaust manifold setup.
