exhaust tube sizes
the stock size is 2.75 inches isnt it? how much power are you guys running before you up to 3 inches? i want to add headers but i dont really want to put on mufflers (although i may put in an X pipe) i will be adding a very healthy cam along with the headres and a bunch of other goodies and im curious if i can just leave the resonator and 2.75 inch pipe and replace the factory H pipe with an X pipe if i will have enough backpressure.

exhaust size
Ive been told that you shouldnt go to 3 inch untill your up around 500 hsp. Im up around 480 right now running hookers and 3 inch pipes back to flowmasters and its pretty loud, I dont think I would run straight 3 inch pipes with out mufflers ,especially if you like your neighbors

A 2 1/2" pipe will flow ~560cfm, so duals will flow ~1,120cfm. Also the system should flow about 2.2cfm/1chp.
So a dual 2 1/2" system should flow to ~510chp before you start to lose power to a restrictive exhaust system. Similarly, a 3" dual system should flow to over 730chp.

Here is a link to chambered muffler eliminators that Eckler's sells.

Hope this helps.
I have been thinking about getting some, but would like to hear from someone how they sound. My guess is they sound pretty good.
