Dont bash me guys lol i know this has been talked about but i would like a little better info as im a technical guy lls ive purchased a set of speed daddy headers i wanted to know is it bolt on? Would i need and fabrication? I saw some people stated that they needed to grab a zzp downpipe 3 inch i believe do i have to buy that as well? Anything else would i need? Wats the estimate time on installing these? Thanks again guys
 


Stepped band clamps 2 3" and 2 2 1/2" if I remember correctly. You can get away with only getting 2 2 1/2" band clamps if you weld the downpipe together. And probably some Ultra Copper RTV silicone.
And you cant use a ZZP downpipe with SD headers. You are thinking of the 3" ZZP flex pipe. Some people have issues with the SD Flex leaking or ticking.
 


Just need better clamps like Slick stated..get Napa easy clamps unless you find those same style cheaper elsewhere. The clamps the SD come with are crappy.
 
Thanks guys thanks for the quick responses!! just grabbed some Napa Clamps about a 1 hr ago as soon as the Headers come in they are goin on the car pics with headers installed hopefully by next weekend...
 


I know what they SDs cost.. I just got mine in the mail today... I meant how much did the clamps cost you?
 
hey if i buy these speed daddys for my 05gtp is it just the 3 inch flex pipe for 14 bucks that i need or do i need the whole 3 inch down pipe also will the 2.5 ich flex pipe work since the exhaust on header is 2.5 inches:
 
They come with a downpipe that is 3in from the rear collector down, then that has a reducer to bolt up to cat-back system.

They don't come with a cat converter so you will need to figure that part out.

The Flex pipe is 3in and if you wanted to swap it for a doubled walled flex, zzp sells them for 25 bucks????? then you just need it welded in place of the old one.
 


Is there a way going around not buying a different flex pipe ? If not ill buy that 3 inch flex pipe from zzp also don't I need a 02 extension ?
 
the sd flex leaks over time. so its your choice, replace the flex now, or do it later when its harder to get too. and you need a o2 extension.
 
I did not need the o2 extension
I tried using the sd clamps... leaky so I got band clamps.
Crossover did not align properly so had to use a thick chunk of wood to help bend it into place.
