haven't tried this myself but they say you are supposed to tune the exhaust for on the spray cause this is where your going to be running when you race.

 

[Everett Goff]

cats got your damn tongues

 

[RayL]

id run atleast 2". Depending on how big maybe bigger.

 

[Coops]

If you're making a lot of hp and spraying the fuck out of it I would go 2 1/8....

 

[Eric David Bru]

Can you put too large of headers on a nitrous engine??

2" 383sbc

 

[WRIGHTRACING]

2" 383sbc

I am guessing these are custom headers cause the ones from hooker are small.

 

[kyman]

Nope not custom. They measure 2". Don't think they are hooker either?

No, I don't believe so.....ultimately with a full on nitrous engine the port runner becomes the restriction.

stahl and hedmon make fendewell headers for the S10 . I have stahl 1 7/8 now

 

[pt race engines]

2" 3 1/2 collector 364" class car record holder.... imo bigger engine= bigger header......... david

 

[John Lowe]

2 - 2 1/8''-2 1/4" w/4" collector 23deg 434sbc ( Lemons built my headers)

 

[Everett Goff]

2 - 2 1/8''-2 1/4" w/4" collector 23deg 434sbc ( Lemons built my headers)

HOW MUCH DO THEY RUN

 

[Mike Beck]

I have 2" primaries from Lemons. Didn't have room for a 4" collector, only room for a 3 1/2". Seem fine for me.

 

[DARKHORSE254]

i have wondered about sizing as well, have 1 7/8 x 3.5 now...gonna try 2x 2 1/8 x 4 on my 382 nitouis sbf. What about the tune up...would it change any?
