I fitted my dual tip to a fully unsilenced decatted, 3" dp single tub, and tbh I didn\'t like it :(
It had that very distinctive, very harsh tone of a rotary where you could hear the \'edge\' of every pulse - almost a bit tinny and raspy :(
I\'ve now had a good friend weld in 2 x 3" bore, 5"x12" straight through silencers, and it\'s back to how I like it - it sounds lovely! Almost all the harshness has gone and it\'s taken on a deep rumble, but is still most definitely a rotary! And that\'s all before it\'s coked up as well. Once it\'s got some miles under it, and I\'ve wrapped it all, it should become even nicer :cool:

interesting si. I have a straight through decat to go on with mine when im ready  to have it mapped so dont know what it will sound like yet. Maybe the single sounds different

It was odd, though in fairness it wasn\'t just the welds that had rusted the entire front "face" of the silencer was rotten right through. I don\'t know how old it was or anything, so maybe it was simply that it was an early one from before they used stailness 100%, or a one-off fault from the factory or a rogue batch of stainless, dunno. I\'ve never met or heard of similar happening to anyone else since, so I don\'t think it\'s a common quality problem.

Figures :rolleyes:

No the only one dude, one of the inners of the dual exit fell out of mine, if you look at the 1st pic DrDan posted you can see the 2 inner pieces i mean.  
A guy in a civic noticed it had fallen out and way trying to catch me up to tell me, and there was me thinking he wanted to race and booted it, took him a few mins to catch up and get my attention.
:Laugh LOL

ok cheers. Guess the porting will make it sound different. Mine basically sounds the same as stock atm.

SiH,
 
I see what you mean about the sound now... it does sound a bit odd.
If I get a moment I\'ll try and record the sound of mine...
