Which Racing Beat header are you guys using? I noticed there were more than one for the Gen 2's.

No trouble w/ emissions in OR, either...



Nemesis: The RB header are specific to; year, turbo/nonturbo, and street/racing, you really can't miss...

You will have to get the Street head, not the race. It has the BUNG..hehe, I said BUNG...

for the O2 sensor. You need that slick..unless you are running an aftermarket ECU, or are

Carb'd.. And Emmissions? HAHA..right..like I pass that ****...we dont have that Tree hugging

hippy **** here.

I passes emissions in NJ with a header and a hi flo cat.

most wouldnt put a high flow cat on, I should have been more specific I guess.

Thanks for the insightful information. Maybe I should rephrase my question. What are the main differences between the streetable header and the road race header? The streetable header looks longer, what are the performance and sonic differences? Are there sensor outlets on the streetable header that are not on the road race header? Which of the two do you guys use? Why?



Thanks.

Yes, I already told you..Streetable has an O2 bung, roadrace doesn't...you can WELD one

onto the race header if you wanted to...and he difference looks wise, is that the street has

collector...race has 2 outlets.

Ok, so running strait pipes from the headers is definatly out of the question.. i guess i'll just have to wait and see what a set of racing beat headers and borla mufflers sound like. Prolly nice.. i hope. Later guys i'll be around
