I'm damn happy with the performance of my 350 (after having driven a 105hp Honda for years), so for the time being, all i want is a relatively cheap way to make it sound good. Suggestions?

 

I’m not sure what good means but there are several ways to make the exhaust more loud:

a. Intake
b. Plenum spacer
c. Test pipes

 

The cheapest way to increase volume, without doing something like running open headers, is the JWT popcharger.

You can start there and see if you're satisfied...

 

Could you give brief descriptions of each, along with prices? Thanks

 

How exactly does this thing work, how WELL does it work, and what's it cost to install (the part itself is $120 apparently). Thanks!!

 

It's an air filter. I hear it is pretty straightforward to install yourself. How well does it work? You can search and find out testimonials or just believe the standard, ~3-4hp gain near the top end, not much gain around 2k-5k rpm...

How have you been here since 2004 and have no idea what a popcharger is?
