    Hey guys,

    I'm soon to get made a custom cat back system on my S3. Currently it has a 3" downpipe with a highflow cat.

    Will be going 3" all the way through, non res. I'm a little worried ill get a 'ricer'/buzzing sound without a res?

    Was thinking something like this but without the res.

    What mufflers will be suitable? Was thinking about a magnaflow muffler or something similar. Really not to sure what will be best.

    I want something similar to this.

    Check out Gops build thread... Bill made him a 3" system and used a Miltek back box.... ideal for what you want I reckon..

    I like the look of the system that Bill made for Staceys S3.

    It's actually not that Loud! It's very OEM quiet on idle and driving about. When I put my foot down, it sounds soooo good! Perfect when cruising, no drone! Perfect IMO, bill made a perfect system.
