What size custom exhaust on a 2.8 with intake?

[4A Play]

Im having a local shop bend up a catback and they told me that their flat rate for a custom Mandrel bent with a magnaflow would be $300 plus tax.

But they refused to make any suggestions because they dont want to be liable for anything.

I have a K&N and thats pretty much all I plan to do with it.

Ideas?

i'd say 2.5 piping with a magnaflow 14816. Thats just my preference but thats a hell of a deal. Any details on where this shop is. Might be worth me taking a drive

Well Im getting a little bit of a discount, My brother has gotten into the habit of finding great deals on Nissan 350z's, having work done to them, and then promptly drifting them into trees.

Just-Right muffler on old 222 in New Smithville or Kempton PA has done about 3 full exhaust systems for him so far lol.

2.5" piping all the way through to dual 2.5" outlets

wow $300 for a mandrel bent catback? that's really cheap. i paid that for a crush bent catback.

I have a 2.8 and honestly, I wouldn't get 2.5" piping. Stock size is 2.25" and unless you supercharged it, there really isn't a point of changing the dia of the pipe. plus, the inlet on the magnaflow 14816 muffler is 2.25" I would trust the audi engineers with their choice on 2.25" pipe. I did and it turned out great. Got a custom catback with 2.25" pipe a small straight through inline resonator and the magnaflow 14816 muffler and i couldn't be happier.
