Hey folks, hoping others with this exhaust setup may be able to clarify something for me.... My S3 is stock apart from the Relentless/XSPower Downpipe and Sport Cat. I had noticed since picking up the car it had a fairly "tinny" noise from the exhaust coming from around the gearstick area or possibly just in front of it and it was starting to annoy me. Since my carpet is currently removed and drying out due to a water leak the noise is even more noticeable and I had always assumed it was just a leak somewhere. At the weekend I managed to get time to take a look and sure enough the clamp joining teh CAT to teh rear section was loose as hell and you could wiggle the whole lot about. I thought to myself, awesome Ill fix this and no more noise............. Nope ! I fixed the leak and although the noise is not as bad theres still a very tinny/hollow noise from it. Is this just how this downpipe and cat sounds or am I possibly missing another leak further up, perhaps the downpipe to turbo gasket ? If this is how this setup sounds then Ill be ripping it off and going back to stock setup i think as I hate cars that sound like they have a leaky exhaust !
