    Exhaust. Info required

    Afternoon all,

    Does anyone know how much a standard S3 exhaust weighs from the Cat back? Or where to find this info out? Bar taking mine off and weighing it...

    I'm looking at getting a full custom titanium exhaust made up as a replacement, with bigger bore. I estimate it to be approx 70-75% lighter than standard.

    Any help would be great, as I want to work out the pro's and cons.

    Cheer, greg

    It made a big difference in weight going from the twin cats etc to larger freeflowing single type,space is tight for downpipe though. [img]/ubbthreads/images/graemlins/beerchug.gif[/img]Andy

    That's a bit serious is it not?

    Does the titanium exhaust give any extra performance, or are you hoping the 70% lighter in weight will be noticable?

    How much more does a custome titanium exhaust cost compared to a standard exhaust, a Milltek or a Supersprint?

    If you want weight reduction, remove you spare wheel, remove the motors for your electrically adjustable Recaro's, remove the back seat etc!

    DAMN Andy [img]/ubbthreads/images/graemlins/ooo.gif[/img] That looks serious [img]/ubbthreads/images/graemlins/grin.gif[/img] Did you have any problems with the S3 hangers? And did you have to trim the rear valance??

    [/ QUOTE ]Drill,i changed to s3 backbox heatsheild and backbox n/s mount is also S3 ,i did cut rear valance and lower bumper .Yes it is a custom front pipe and 100 cell cat made by Z-EX in cardiff,they have also done some ibiza turbo ones for my mates,this is their 5th custom vag downpipe.It also goes much better,especially midrange,with hopefully more to come with FMIC and custom revo map adjusted for mods [img]/ubbthreads/images/graemlins/dancing.gif[/img] [img]/ubbthreads/images/graemlins/beerchug.gif[/img]Andy

    Re: Exhaust. Info required

    Thx Andy [img]/ubbthreads/images/graemlins/beerchug.gif[/img] picked up my heat shield and hangers yesterday [img]/ubbthreads/images/graemlins/grin.gif[/img] Any chance of a pic of the rear valance so I have an idea how much needs cut?

    And Pete, any idea if the S3 exhaust weighs more or less than the A3 Quattro one?

    Yeah, me too, but just thought that if you had the S3 weight, you might have the TQ as well [img]/ubbthreads/images/graemlins/grin.gif[/img] Couldn't hurt to ask, right? [img]/ubbthreads/images/graemlins/cool.gif[/img]

    Thx [img]/ubbthreads/images/graemlins/beerchug.gif[/img]

    Re: Exhaust. Info required

    I used sheet metal shears,but they weren't very sharp,will use a dremel cutter to tidy up edges.Cut bumper out roughly with shears and then tidied up shape and edges with a good stanley knife.Watch your fingers and don't forget to rustproof where you trim valance.Is vortex skirt plastic or fibreglass ?Just take your time and cut out small pieces,if you try to cut too much out at once,thats when things go wrong.Measure twice ,cut once [img]/ubbthreads/images/graemlins/beerchug.gif[/img]Andy
