Exhaust questions? Welding, mufflers, tips.

[muddpile]

I have the exhaust run about a foot behind the cab, but from there on I need to complete my system. It is dual 2", and I need mufflers and tips, and an exit location. The truck is a LWB with the stock sport rear bumper. Is there a standard exit location, or a standard tip style that everyone uses? The truck has a blazer tank back there, so that has to be taken into consideration as well. Here's some other issues:

-Mufflers: I want a louder low rumble. The truck has a mild cam and ramhorns. Does anyone use Hooker Aerochambers, or are Flowmaster 40's the standard issue? I've also considered Flo Pros.

-Tips: Where they exit and what they look like. Pics would help.

-Welding: What do I weld and what do I clamp? I was planning on welding everything, but is it a good idea to clamp the mufflers? I usually do the whole exhaust when the mufflers are done, so removing the clamps won't be necessary.

-Welding: I will be using a gas MIG welder, but what thickness of wire do I use? The same .023 or whatever that I used for the bodywork?

Thanks!
