A4 tfsi stainless steel system and tail pipe size

[Ali2.0tfsi]

hi guys

Going next week to get a stainless steel cat back system fitted

Just wanted to ask what size tail pipe do people recommend?

Thanks

What diffuser do you have on the back? Try and get ones that fill the cutout best?

I have the sline diffuser hole in each side.

Pretty sure you can squeeze 4" tips in the cutouts, 3.5" gives it a bit more OEM look imho. It's really just a case of personal preference.

If it's a custom system you're getting they'll probably be able to show you the best options
