Exhaut tip/big muffler ?'s
Hey all, I am putting a new exhuast on my S4 base pretty soon (Mods are new rebuild, intake, RB RR header that will be collected, S5 intake manifold, ALuminum Flywheel and some other stuff). But with my Road Race header, which will be collected to 2.5in piping and will be using A Borla XR-1 Sportsman as my muffler, might have a presilencer on there as well. But I was wonering if there would be any benifits of using a larger tip and the end of the muffler, or using a can type of muffler like the N1. Will these just be louder?

You will want to put one of the RB Presilencer's on, so that the 5th and 6th ports still open up, or else you will have to wire them open, and sacrifice low end power.

All a large tips are for is looks and maybe some kind of a sound difference, but I can't emagine that it would make it sound better since it would just resonate a little bit. That is my 1 cent.

No, but you do need back pressure to open the six ports on an S5 intake. And the presilencer gives you more back pressure. And that pipe is not for the 5th and 6th ports it is for emmisions.

You are incorrect. You dont need backpressure from the exhaust to open the 5th and 6th ports on s5 cars. The air pump is what opens them on s5 cars. The s4 cars are what use the back pressure from the exhaust to open the ports.
