Ok, well I just bought an 88 mustang lx and found this wonderful place to ask for advice. So, here I go. For some background I found this car in the mountains of NC and bought it for $900. It has 66k original miles and is in really good shape. Typical aged paint job and worn interior. I am just curious what I can do to squeeze a little extra horse power out of it without doing too many mods? I can't really afford to convert to turbo at this time. Really just looking for simple things I can do. This is my first mustang but I am an OK mechanic. First thing I did was remove the air filter silencer and remove my AC belt. AC has been dead a long time. I put some new plugs in it and put a K&N air filter. This has made it much more responsive already. Are there any other easy mods like this I can do? I am also going to replace the exhaust, that thing is rusted to pieces. What should I think about replacing the exhaust, I would like it to have a nice sound also, not like a ricer. Anyway, thanks in advance. If I can figure out how I will link to some pics soon, in case anyone is interested.
