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.
