Does anyone have the BCS cat back WRC system on their S3 8v?
What’s the noise like on cold start up? Is it OEM or louder?
Also does anyone have the BCS anti drone pipe with their flaps open all the time? Is there any drone?
Thanks all in advance
I have always been under the impression my S3 8v pre FL (2015) had a cambelt and I’m lead to believe the interval for changing these is every 5 years or 60k.
After a little Google I’ve found various posts stating my engine is chain driven and doesn’t need replacing for the life of the...
From what I understand Unicorn create the pops/bang from some sort of thermal wizardry which prevents the cat from being damaged. Whereas Revo and MRC create the pops/bangs via a different route (possibly ignition timing/fueling) which unless you have decat will have a detrimental effect...
I’ve literally just read through this entire thread tonight (it took some time) but it was well worth it :) - fantastic car and great posts.
Since going Stage 1 up to the current day, how many miles have you covered? Have you ran into any faults?
I know Revo are a incredible company and put...
I’m going to assume the more expensive one will include the sports cat too. I’d personally go for the cheaper option and just get a cat back system from them and if you want it to be loud then opt for the WRC system if you just want it sporty opt for the SPORT system. Both feature zero drone...
After trying various exhaust brands and never being happy, too droney, too quiet etc. I’m looking at going for a BCS Cat back - lots of noise when you boot it and quiet when driving normally.
Has anyone got one on here? What are they like long term?
Is it worth going to their shop...
I’ve recently had my stock S3 exhaust refitted and can’t help notice the tips appear to hang a lot lower than they did originally - is this just in my head because I’m used to aftermarket exhausts filling the gaps more or do I have a problem?
Thank you :)
I will be selling it yes, along with all my mods as I’m putting the car back to stock.
I kept all my OEM parts so a swap won’t help but I will be selling.
My car is having the standard exhaust and detune done Thursday and after then I’ll start removing parts/bolt ons
I’m not sure if Audi have changed their stance on this but it’s has been a well documented fact (examples easily found on this site) where Audi will only replace haldex oil they won’t actually clean the filter element where as an Indy will clean the filter element.
My car is coming up for its first service since I’ve owned it (currently full Audi service history) it’s due it’s interim service which as we all know is basically an oil and oil filter change.
I plan to use the stealership for servicing just until the warranty runs out (2021). I will of...
After a recent cat removal, I have noticed an awful rattle/noise around 2k. It feels like the whole dash board and centre console are rattling. I’ve put my hand on the roof lining and can feel it vibrating there.
Is this normal after a decat? Will it settle down after a while or has something...
I’ve recently changed exhausts systems and although it sounds amazing on WOT, the DSG noise and overrun is extremely muted. This is possibly down to the big centre resonater that comes with it.
I originally had a resonated Cobra cat back and that was loud with plenty of DSG noise...
