Some exaust questions

I am planing on putting an exaust on my 2000 chevy blazer 4dr 4x4. I am pretty sure I am going with the Super 40 Series since it gives the rumble sound I am looking for. I have a few questions though:

1. What is the in and out size of my stock system so I can find the right size muffler to buy.

2. Should I just buy the Super 40 Series muffler like on ebay, or should I get all the piping also?

3. I see that some people run 1 single pipe into the muffler and dual out, wont this not create enough back pressue for the engine and make it run different?

1. 2.25" offset inlet/center outlet..........
2. just buy it at the muffler shop, it'll be about the same price......
3. you can't run duals on a 2000 4x4 without lifting it or removing reese hitch and spare tire....duals just aren't in the cards for stock height...

If you do a cat-back system there is no problem with back pressure since it is the diameter of the exhaust manifold/downpipe/catylitic converter that will determine backpressure in an exhaust system. You should be fine but I would upgrage the piping to a min. of 2.5" mandrel bend or 3" pressure bend pipes. The only real area that will cause a problem with your method is the area of pipe behind the muffler that goes "up-n-over" the rear axle, most of the other piping in front of the muffler and behind the converter can be pressure bends since they are not that drastic.

RE: Some exaust questions

I took a look at the muffler today and saw that the stock muffler is at least 3 feet long if not more. From the pictures the Flowmaster Super 40 Series is only like a foot and a half. So what do I have to do to take up the space that will be missing?
