B5 S4 & RS4 Exhaust Options

[philipwalker]

Sebring are worth a look Top quality good fit good power gains
The S4 has a twin box system available
The RS4 has a single box system available
Both fit onto the original down pipes not loud, the RS4 is similar to the equivilent twin box Miltek.
They are priced at around £400, I think I have a RS4 system here.

Mine: RS4 Dps totally decatted mated to an s4 3" single milltek catback(actually with a scorpian back box becasue I used the spare parts in the shop) Not loud enough - the 3" single strangles power.

A 3" single is a very quiet exhaust, even with no cats.

A Milltek dual with stock or rs4 DPs and no precats is louder/boomyish than the 3".

You can fit an S4 catback to RS4 downpipes by using the milltek downpipe joiner pipes.

The dual exhaust we do is dual 70mm internal all the way with no cats and the option of 1 or 2 boxes, and with S4 or RS4 tailpipe option and with stock flanges or with RS6 flanges. Surprisingly the 1 box option is not too loud on idle and part throttle driving. WOT it sounds really nice! These are fitted to the 600bhp RS4 engined cars.

An RS4 with 3" downpipes and no cats and no catback is loud - really loud - There will be a video of that sometime soon...
