I am currently looking at some headers for sale, and the guy doesn't know if they are LS OR GSR Headers. Does anyone know the difference between DC 4-1 headers? Does someone know a way I can distinguish the difference between them? Please let me know. Thanks.

 

They will fit regardless. Same size flange

 

No they won't. The collector on the 94-01 LS is longer than the 94-99 GSR.

 

i just went throught that whole thing, the downpipe is about 1/2"-1" shorter on the gsr and the opposite on the ls. i just ended up getting some pacesetter headers and they bolted up just fine, for the value of the headers i would go with pacesetter. but it is ultimatly up to you. also i would recomend an aftermarket cat.

 

Get the carb number and look it through the bureau of automotive repair. The carb number will say exactly what model the carb number is intended for.

 

Pacesetter? :down: you'll be sorry dude. They are affordable for a reason.

 

Really, yet another thing I learned. However it will work w/ an LS/Vtec correct?


Would I have to get a different header for a B20 block?

 

Does anyone know where on the Bureau of Automotive Repair website I can lookup carb #s?

 

nvm, sorry, found it

 

no... the header does not come out of the block... the header comes out of the head... so w/e head you put on there is the one that needs to be matched to the header...

b18b + b18c1 = gsr header
same goes for type R... or 1.6 header
