Ok i am brand new on the site i am about to put LONG TUBE headers on my 2002 silverado 1500 put i just do not know what to do after the headers i was thinking about Straight pipes to 10 Series but then i worry about losing power i want the most power out of it plz help

 

is it lifted that you can put straight pipes? most on here use an aftermarket y pipe with a single 3 muffler but all depends on budget, engine size and mods....

 

Yea it has a 3" lift with 33x12.50 16 i have no
Cats into 44s now i have a cold air intake throttle body spacer superchip cortex and like some small stuff like msd wires and better spark plugs but im really looking for some power with the long tubes will i get that? And what muffler of flowmaster but still loud

 

Loud but good sounding

 

Put a spintech muffler on there, y pipe and get rid of the super chips and have a real tuner tune it ie blackbear, Wheatley, pcmforless

 

That thing will be loud. I would do Y to a single 3" muffler (I prefer Magnaflow)

+1 on getting a real tune

 

+1 on the tune and get rid of the throttle body spacer while you are at it.

if long tubes fall out of your budget you could always grab a 07+ intake manifold and a nice 90mm throttle body for around 500 and you will really feel a difference there as well

 

I have to replace my intake manifold now sso i should buy a 07 for mine and is the throttle body spacer hurting me? And i do plan on getting a black bear tune after headers and yall must not like flowmaster lol

 

Do i have to do any custom stuff to put the 07+ intake in my truck

 

you have to buy a corvette fuel filter for the fuel lines to connect or you can modify your stock round rails to fit over the intake. the spacer is not hurting you but its not doing you any favors. unless you plan to drill and tap a nitrous nozzle in it.
