Will this setup work?
 

Ok I think I am going to put in my order today for my exhuast components and I want to make sure everything is going to work.

setup: RB downpipe, presilencer, corksport catback.

My questions:
1) Will all these components simply bolt-up to each other? If I get, say, the RB gasket for pre-silencer to stock catback, will this work with the corksport catback as well?

2) Do you recommend I get the RB headers now as well...since I'm going to be changing it all anyways? WIll it save me trouble this way?

3) What is a presilencer...just a muffler where the cat goes? Will this give my car a nicer exhuast note? Cause it's pretty expensive, so is it worth it?

Any other tips and suggestion are appreciated!

why not just get the whole racing beat setup? It's tuned to work properly with itself

ditto - mazdatrix sells a full exhaust system. ie - everything you need for a direct replacement and you can op for the cheaper dynomax mufflers if you prefer.

and yes, changing everything at once would be way less of a hassle.
