I haven't looked for any mod products, but I did gut the pipe. Not much louder and a little more power. The trk is a brute ( LE ). It is what it is and to lighten it up much would prob be cost prohibitive unless you've got your heart set on it. The GEN LE with the MX3 radio is actually pretty cost effective. I got mine for $530 out the door. No complaints so far, other than a boring day idling 7 tanks thru it. Take your time and break it in their way. You'll prob see a max temp of 100 or less during your idle brk in.
