Roush quiet tails
Discussion

I'm concerned that with the Roush fitted I'll end up being over some track noise limits and I've heard there are quiet tails available. Where, how much and how do they work?
I was wondering whether a stainless sleeve, slid into each tail might do the same trick?
I have the quiet tailpipes on mine but it is still too loud for some circuits. I think last time it was tested it came out as 105db static! I was wondering whether a stainless sleeve, slid into each tail might do the same trick?
I think the back boxes may need repacking but I am not sure how feasible that is.I've just had my Roush repacked with better baffles and wadding.
At the same time it had been modified to be easily repackacked if need be.
I also have a set of quiet tail pipes, although I have not used them yet.
Last time I was static tested it was 121 dB so obviously something had to be done !
When its all back together I will get it tested with the normal pipes and quiet pipes fitted and report back !

I just had my friend remake another friends roushe exhaust to be both repackable and use the internals that my silencers are made of.... cost less than 400quid and we expect it to be fully track legal and remain so as the internals don't allow the wadding to be blown out like the stock system.
will report exact db figures at the next track day he goes on, but considering my car is a little mad and easily passes both drive bys and static I am very confident he wont need those extra tail pipes again.
BTW even with those additional tail pipes he failed track day noise tests hence the silencer mods.
edited to say I see steve beat me to it.

121db static? Yikes!At the same time it had been modified to be easily repackacked if need be.

Does anyone have any vids or sound clips of the roush exhausts on a nob? My youtube-fu is failing me...
My Urban Racing came in @105 db Oulton Park limit was 106 db (I think) got a track day booked at Castle Coombe and I have a nasty feeling. One thing I noticed was my car was no where near as lould as others screaming about. When in scrutineering I was asked what my red-line was, would a little white lie help??

Castle Coombe will be 100 dba max, redline is 6000 rpm 
when are you going Paul ?

Standard engine with standard Roush cats plus quite tail pipes = no problem at any circuit.
thats assuming you still have wadding left in your silencers... even steve's used to pass track noise tests.GTO600 said:
