Factory Exhaust Question

[Turbo Keith]

This is just something I have been wondering about , How far would the stock exhaust take you time wise ? 11 ' s or even faster ? and I'm asking the ? because I have factory exhaust with an electric dump and hate the damn set up , The car is tuned with the dump open and I just don't like it . So I'm planning on Santa bringing a new 3 " exhaust but with my set up as you can read below , So what should I expect to gain going with a new set up vs my stock exhaust ? And its in great shape and love the way it sounds . Thank you Guys for the feed back , Keith

I would say low 12's.. with stock cam & ta49 I would think your 3" dp to straight test pipe into 2.5 inch pypes system would be optimal for you, be a nice upgrade over the stock 2.25" yet save some weight over a 3" system.. Not sure if your relatively low rpm power band would require 3"?
Just my school of thought could be wrong..
