Stock downpipe diameter??

[6spdterror]

As the title says....whats the diameter of the stock downpipes? Im in the market for catless DPs and trying to figure out which ones i should go with

I just put DP on my car, the stockers are about 3.5" at the turbo then the cats have to be 6" wide back to 3" then 2.5" where it connects to the mid pipes.

Your over thinking it.
I have the undercover catless DP they fit great and work great.

I'm sure the AMS DP work good aswell.
If you had the 2 put on, I don't think would be able to tell the difference.

Thanks for the input! Those are actually the 2 im considering. Undercover is local to me so if i go that route ill just have them do the install.

The undercover ones are nicer then ams and better design by far ! And their full system is bad ass and probably the loudest on the market over rpi
