If i buy a racing beat header, does that replace my stock exhaust manifold - in the picture it looks like it seperates into 2 pipes, so both connect to the block and completely relace the manifold...? Will my racing beat exhaust still fit on?

Yes it replace the the stock manifold exhuast entirely.

Mobius

oh and your other exhuast parts shold still fit. I think the rear cat will be al that's left, because a header replaces the first two precats

it replaces your exhaust maifold and your pre-cat(s)

You will need to fabricate a small section of tubing to fit betweeen the header and your stock main cat, or you can but the pre-silencer and run without the cats completely. The Header pre-silencer combo will bolt up to any cat back exhaust, but a header alone will not bolt to the catalytic converter.

i agree completely... look at our sigs....

yeah it will replace your pre-cats and if you got the presilencer it will elimanate your main cat. after all that you should be able to throw flames

I recently got a straight pipe to replace my main cat. I am thinking of RB headers next because my precats have an exhaust leak. Will this bolt directly to the pipe I just had made to replace main cat or will straight pipe need to be lengthened? I have stock catback. Thanks.

it'll probably need to be lengthend. I'd just have them make another one that fits correctly. At the temps in that region you don't need the extra breaks in the aluminum coating on the pipes. (rusts faster at every weld)

You guys with presilencers... Have any of you run straight pipes? I'm curious as to the power difference and sound quieting of that piece. I have straight pipes and its really loud. Does the presilencer help without killing any power?
