Headers or plog/3"dp?

[GMCARS4LIFE]

Which would be better for a 3.4 setup?

If your planning on going any further I'd say headers, but on the other hand for what headers cost now a days just get the headers anyway.

just go with some speed daddy headers they are 220 for a set only things u will need is some copper rtv and some better clamps DO NOT GET OBX HEADERS!

 

[TorqueAutoMotiv]

id go with headers due to cost and the fact they let you mod further if wanted

 

[GMCARS4LIFE]

Thanks for the input guys. Would this be a good setup headers, cai, tuned pcm, 3.4 pulley, 180t-stat and 104s

 

[GMCARS4LIFE]

Also this may sound dumb, but can you use a 3"dp with ssac headers

 

[Poil336]

you don't need to get a downpipe with headers. the same part of the exhaust gets replaced

^^what this guy said..headers come with dp's. I would say if the furthest you're going to mod the car is a 3.4 then get a plog/downpipe for low end torque and you can always find them dirt cheap in classifieds, but any smaller of a pulley you'll want headers for sure.

Get speed daddy headers. Headers are always the better option unless you plan on going turbo.

Unless you wanna cam and go I/C'd

and those help exhaust flow how?

Hurr? I'd like an explanation of this, too.

 

[matt5112]

They dont.

But they still let you run a smaller pulley and go faster.

But headers are the best idea, just not necessary. Think Cali.

with speed daddys, can i keep my stock cat? or would i have to cut and weld it into the dp?

 

[blueguy]

Your call chief on that one. I'd get a 3" Cat and slip it in there if I were worried about emissions...if not they come with a 3" test pipe
